To celebrate Heritage Audio's 15th anniversary, Heritage Audio released a limited “Black Edition” of the Baby RAM. The Baby RAM has been the ultimate passive-monitoring system for the past 6 years, delivering the most transparent signal with the best stereo imaging of any other passive designs available! A Baby RAM is the ultimate controller for total transparency — a zero-compromise signal path, paired with a simplified control set ensures your monitors receive the cleanest, purest signal possible without unnecessary complications. The Baby RAM proudly features a 4-gang, 24 step rotary switch for volume as opposed to cheaper stereo potentiometers, which means the precision of your stereo signal is perfect on every position as well as offering a subtenth of a dB precision on every single attenuation position! Baby RAM also has no insertion loss, meaning that there’s no extra coloration, signal loss or degradation at any settings. Even though the Baby RAM packs a zero-compromise circuit design, it couldn’t be any easier to use with 2 pairs of stereo inputs and outputs — both balanced and ground free (unbalanced compatible) on gold-plated TRS 1/4¨ jacks. Mute, Dim, Mono, and Volume monitoring controls make the Baby RAM a breeze to work with. And with its passive design, it also means you have no concerns with bad power supplies, as no electrical current is needed! The Baby RAM is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners.

The TUBESTRIP combines 4 essential top-notch processors into one convenient 3-unit high, 7,6 kg, the ultimate all-tube recording channel. Packed with the best selection of tubes available, custom-made transformers and inductors you can certainly expect a very exciting and evocative sound that will bring recordings to life. The TUBESTRIP has the tools, the character and the intelligence to take Vocals, drums, guitars, bass, keys, room mics, acoustic instruments… exactly where they need to go. One unit. One signal path. Four processors working as one coherent instrument, each one drawn from Heritage Audio's deep engineering knowledge and from some of their most popular designs. THE PREAMP: MORPH The input section of the TUBESTRIP is a transformer-coupled tube-based amplifier offering up to 60dB of voltage gain and unrivalled flexibility when it comes to initially shaping the signal. The clever MORPH section allows users to select and blend between different modes, essentially offering a wide range of distinct preamp personalities. It can help emphasize warmth and smoothness in Triode mode or add more bite and attitude to the signal when using Pentode. In UL (UltraLinear) mode, the unit provides characteristics that fall between the two other options. With enough headroom, it can effortlessly manage any signal, whether from a microphone, LINE level, or DI for instruments. Additionally, an output attenuator positioned directly after the preamp section allows for any necessary adjustments before the signal proceeds to subsequent processors or recording devices. THE EQ: TYPE 69 The inductor-based EQ section, inspired by an innovative and legendary English design from the late 1960s, enables users to sweeten, soften, enhance, or focus any sound to meet precise requirements. Its clever layout provides the tools to efficiently sculpt the signal for both creative and technical needs. TUBESTRIP includes two tube compressors for total level and energy control and shaping. VARI-MU COMPRESSOR The first one is the Vari-Mu compressor and it steps up to handle any and all dynamic control that may be needed. This is based off of the Heritage Audio LANG P.Lane design and great for thickening signals and giving them that extra excitement, incredibly maintaining transients and letting the signal breathe, even under heavy compression. For more flexibility the order between the EQ section and the Vari-Mu compressor can be switched. OPTICAL COMPRESSOR The optical compressor is setup with short attack and release times for smoothing out any take and avoid any unwanted peaks as well as provide that classic, lush density that suits vocals so very well. It can also be turned into very organic and natural sounding de-esser with exact frequency adjustment for transparent and musical sibilance control to cover all singers. The OUTPUT section provides an attenuator covering the range of -14 to +6dB to perfectly adjust the output level for the following signal chain.

The MIX BUDDY redefines what a mixer can be, offering the first-ever instrument-focused design with an unprecedented 19 inputs and 8 outputs. Unlike conventional mixers built for microphones and line-level sources, this unit is engineered from the ground up for instruments, delivering unparalleled clarity and tonal integrity. At its core, the MIX BUDDY features two distinct gain input types—Hi Gain and Unity—both built around the legendary Toshiba 2SK JFET series. They ensure that every signal, from passive basses to modern synths, retains its natural character without noise introduced by generic mixer designs. The Hi Gain inputs add a touch of musical saturation, while the Unity inputs provide pristine, transparent amplification, making it the ideal solution for both acoustic and electronic sources. Flexibility is at the heart of the MIX BUDDY’s design, with features that streamline workflows for studio and stage alike. The MONO + THRU function allows any instrument to be sent to an amplifier or external processor while remaining in the mix, enabling parallel processing without complex setups. The built-in mic preamp, combined with the AUX effects loop, unlocks creative possibilities by allowing vocals to be processed through guitar pedals like chorus, delay, reverb, or distortion directly within the mix. The PRE mode transforms the effects loop into a true parallel processor, a feature typically found in high-end studio setups, now accessible in a compact desktop unit. With two master outputs—one transformer-balanced for warmth and one transformerless for pure transparency—the MIX BUDDY adapts to any environment, whether recording, performing, or monitoring. Built with Heritage Audio’s commitment to uncompromising signal quality, the MIX BUDDY is more than a mixer; it’s a creative command center. The stereo FX loop integrates hardware effects seamlessly, while the independent headphone amplifier ensures precise monitoring. From home studios to live stages, this unit consolidates the functionality of multiple devices into one, eliminating workarounds and delivering professional-grade results. The MIX BUDDY offers musicians and producers a tool that finally meets the demands of modern instrument mixing.

The RAM 1000 Desktop Monitoring System is the perfect option for self-recording musicians and mid-sized studios. Designed with the modern musician/producer in mind, it includes a few new features to keep studios up to date. Bluetooth reception has become just about essential in any modern-day studio environment and is easily used here. Allowing to play along with the mixes and rehearse them until the musician is content... then with a simple push of a button the recording session can be started and audio send on to the DAW interface to record the track. Couldn’t be easier. The RAM 1000 is easy to navigate and things are kept simple to make sure they don´t interfere with creativity. Operation is intuitive with 3 selectable input buttons to the left and 2 output buttons to the right with a huge, beautiful Marconi type knob dead center for volume control. All inputs and outputs are simultaneously selectable. The addition of the ubiquitous MUTE, DIM and MONO keep those options within reach. There has also been a high-quality headphone output included for critical listening decisions that only headphone monitor can offer. Bluetooth has basically become a standard within studios around the world in the last few years. The RAM 1000 provides a selectable Bluetooth input which supports all the latest CODEC options to insure the highest quality transmission possible As an extra, INPUT 1 can be switched directly to OUTPUT 1 for recording an instrument to an audio device.

The OST-6 V2.0 500 series enclosure is designed for racking any and all 500-series modules and devices, including ‘double wide’ modules and even the most demanding class-A and vacuum tube designs. The OST-6 V2.0 enclosure features Heritage Audio’s On Slot Technology, providing maximum protection, filtering, and isolation to each channel. While most 500-series enclosures on the market have a relatively simple power supply design essentially feeding every channel in parallel, each channel of the OST-6 V2.0 enclosure has its own power supply, individually regulated and isolated from the rest. This ensures that every 500-series module installed will perform at its peak potential, and that no ‘ power hungry’ or even a faulty module will compromise the performance of another. In addition to reducing interference, many 500-series devices actually exhibit lower self-noise and better performance when racked in the OST-6 V2.0 enclosure, specially mic preamps. A new and exciting feature in the V2.0 model is the Link feature, allowing each channel to be linked over to the next at the push of a button (via back panel), no patch cables required! As with all Heritage Audio products; the 500 Series OST-6 V2.0 enclosures are built utilizing the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners.

The i73® PRO Edge is the first ever USB-C interface with two built-in pure Class A 73 style preamps. It aims to provide musicians, producers and audio engineers with an easy path to that cherished analog experience that have inspired music creation since the early 70’s. The i73® PRO Edge incorporates the same Class A transformer-balanced circuitry as the Heritage Audio classic 73 style preamps and provides all that classic mojo and vibe straight from the i73® PRO Edge to the computer. As with any of Heritage Audio’s 73 style preamps, a three way input is with true studio quality implemented: A hearty MIC preamp with up to 70dBs of gain, an electric guitar/bass input with a fast, dynamic JFET DI and a clean LINE input. The i73® PRO Edge provides two additional LINE inputs and allows to connect eight additional analogue channels via ADAT in/out. But a 73 style Class A preamp is only the gate to get to the Full Analog Experience. A low latency monitoring mixing console has been developed from the ground up with an independent configurable mix for two different speakers set and two headphones cues within the Heritage Audio MIXER running inside the i73® PRO Edge. An integrated DSP allows realtime processing within Heritage Audio’s MIXER with an ever growing comprehensive set of tools modeled after Heritage Audio’s own outboard and private gear collection. It is also possible to insert third party native plugins via the MIXER’s Aux channels. For later post-processing and maximum flexibility, the WET and DRY signals can be recorded simultaneously in the DAW. i73® PRO Edge provides the right tools to monitor audio just like in the Golden Era of recording studios out of the box and capture this sound right into the DAW with the advantage of a modern home studio workflow.

The 73EQ JR is a fully featured Line Input module for the 500 Series. It not only shares the 3-band Equalizer with his big brother, the 1073, but also shares the same transformer coupled line preamp and Class A transformer balanced output stage. These facts make the 73EQ JR unique on its class, being able to capture a full transformer based, Class A sound without relying on external preamps. The Equalizer features the same Baxandall type High and Low shelf found in the 1073, with the addition of a high frequency selector switch. 4 different frequencies are possible instead of the fixed 12Khz one. The mid band is the same exact dual inductor 1073 one, thick low and sweet high midrange boosts without being muddy or brittle! The line preamp has a range of +6 to -20dB, allowing heavy eq boosts without overloadingA/D converters. Finally, special care has been taken with power handling, implementing internal +24v slow turn on regulation (about 20 seconds to reach full voltage ). This makes the 73EQ JR independent of the rest of the slots and makes lunchbox´s PSU happier.

The Heritage Audio Successor is a true stereo bus compressor with matched channels for precise left-right compression and virtually no channel offset. In addition to the single-ended Class A output stage in the style of the legendary 1073 amplifier circuitry, the Successor relies on transformer-coupled, balanced inputs and outputs based on a Carnhill transformer for an additional vintage character. The diode bridge circuit adds 2nd order harmonic distortion characteristics and true vintage tone while eliminating nasty odd harmonic content. Thanks to its modern circuit design, the Successor offers ultra-fast attack and release times never found in vintage designs and allows even FET-style bus compression with significant loudness maximization, without affecting the transients by sound artifacts that occur. Furthermore, the bus compressor shines with versatile sidechain options. Not only the usual high-pass filters are available, but also various peak filters in the mid-band for particularly flexible bus compression. The Sidechain SEND and RETURN connectors also allow external sidechain signals and further external processing of the internal one. In addition, the Successor's rasterized blend control enables parallel compression including the Blend ON/OFF button for direct comparison between wet and dry signals.

The LANG PEQ-2 Program Equalizer has been a powerful secret weapon for many during the last 60 years and is now available to everybody once again thanks to the rebirth of LANG Electronics Inc. acquired by Heritage Audio. The PEQ-2 is a very high quality passive equalizer with inductors and build on the same patented Western Electric design, as the ubiquitous Pultec program equalizers, but thanks to the solid state output amplifier the PEQ-2 offers a sharper, tighter response and makes it ideal for mix bus and mastering use. A few important differences between the two legends are: The PEQ-2 has nearly twice as many frequency options to choose from… 26 compared to the Pultec´s 14. The low end is infinitely more controllable as the LANG is able to Boost and Cut at different frequencies, unlike the Pultec. There is also a very useful 20 kHz option in the High Peak Boost section that can really be helpful. Lucky Engineers who used the old PEQ-2 stated that they actually prefer the PEQ-2 to the Pultec and have become their secret weapon and totally rely on them to produce their trademark sound, including Allen Sides, Andrew Sheps and Joe Chiccarelli just to name a few. While having a very simple and easy layout, the PEQ-2 can be deceiving as it is actually capable of some very extreme processing all while maintaining the musicality of your signal. With independent controls for Boost and Droop (Cut) for both the High and Low bands you can quickly transform your material in interesting, creative ways that you have almost certainly never considered before and are not even possible with the Pultec design. Once you’ve tried molding your mixes with these you’ll wonder how you ever managed before. Not only does the PEQ-2 offer Low Shelf boost and cut control and High Shelf cut, but it also has a High Peak Boost with a completely variable Q (Bandwidth) setting that spans from Sharp to Broad to cover any needs. What’s more, the range of Boost actually varies depending on what your selected Bandwidth setting is to offer a very smooth and natural response at all times… Very clever indeed. The ability to boost and cut at the same or similar frequencies produces exciting new equalized response curves. Experimentation is key, but you will quickly realize just how powerful this feature can be. Within no time the PEQ-2 will most likely become one of your most used studio tools. The sheer power if offers with the ease and speed of achieving results is impressive…and addictive. Heritage Audio is on the scene to make this nearly lost treasure available to any and all. After months and months of studying the originals, the PEQ-2 has been reborn and is back by popular demand. Like all the Heritage Audio products, the LANG PEQ-2 comes equipped with custom audio transformers at the Input and Output to make sure you always have a powerful, solid, noise-free signal to work with. Lang Electronics Inc. was famous for providing very high quality equipment at reasonable prices and Heritage Audio is intent on maintaining that philosophy.

The Heritage Audio Frame 8 For Neve "80" Modules is handmade in the EU employing the same exact ISEP mechanical components used in the Series 80 consoles: aluminum rails, guides, etc. This will ensure the vintage modules, as well as any that are currently made, will fit like a glove. Every channel has its own output control as well as illuminated phantom switch. Also, the Frame 8 is ready for linking up to eight 2264 compressors in two busses, A or B. Back panel features Neutrik gold-plated XLR connectors for Mic and Line inputs, as well as outputs. External Power Supply Unit is connected via Neutrik gold plated 4-pin XLRs. It is configurable for 220 to 240 volts or 110 volts. The power supply is included.

The P DI 2 is a dual channel fully passive DI box, based on quality custom-made transformer for exceptional professional studio recording, as well as live use. Thanks to its passive, power-free design, the P DI 2 converts the impedance from high to low and balances the signal using a magnetic transformer that transfers audio while blocking unwanted DC voltage and RFI. This makes it especially effective at eliminating hum and buzz from ground loops while maintaining the tone of your instrument at every stage. An additional 15dB PAD switch helps with hotter instruments and even allows speaker outputs to be plugged into the P DI 2. A THRU parallel connection for forwarding the input signals is also available. Transformers are the main ingredient on any high-level passive DI and the only way to master the transformer world is pure experience. Heritage Audio spent the last 15 years designing custom-made transformers and mastered transparent passive signal handling with the R.A.M monitor controller series. The P DI 2 is based on new designed HA-DI transformer. It has the ideal combination of a nickel core for an ultra-transparent signal transfer and MU Metal shielding for protection against any unwanted noise or interference caused by outside sources. The P DI 2 works best with active circuit instruments like keyboards, synths, drum machines, samplers and some guitars and basses, when they are required to be plugged into a PA or recording system. By matching the instrument’s output level to a typical microphone level, converting it to a balanced signal and minimizing noise, the strongest, clearest signal can be achieved.

The Heritage Audio ELITE series is a budget-friendly version of the widely respected, hand-wired 73JR and DMA73 preamps. A combination of mass production, lean manufacturing and modern construction techniques makes it possible to offer a zero compromise, high quality yet very affordable series of products. The HA73 ELITE microphone preamplifier is based on the iconic 1073, amplifying any microphone or instrument with vibrant clarity and punch. On driving the input harder it provides the saturated sound as known from a vintage console. With 80dB of gain the HA73 is suitable for any type of microphone - condenser, dynamic, or ribbon. The hand wounded Carnhill input and output transformers add warmth, girth, and authority to any sound source - mic, line, or even DI instruments. The separate input and output gain controls make it easy to control the transformer color without overloading the output stage. The DI circuit is ahead of the mic input transformer, perfect for adding some character to DI bass signals on the way in.

70 years after it’s creation, the Baxandall EQ gets a definitive update. Baxandall equalizer’s topology, introduced to the public by Peter Baxandall in 1952, was a very ingenious way of obtaining high and low shelves with boost and cut option without using expensive rotary switches. This affordable circuit was soon adopted by hi-fi and console manufacturers for its simplicity, where parametric options aren’t needed. Heritage Audio has successfully replaced the Baxandall topology with a functional equivalent — a much more musical one, implemented as a one rack space, master bus/ mastering type unit. The Stereo Asymptotic Equalizer, affectionately known as Symph EQ, takes its name from the shape obtained by its shelf curves; where the boost or cut amplitude grows up until the asymptotic value is reached, keeping the ultra highs and sub lows always controlled. Its sound can only be described as tight, sweet, and natural, and its use of parallel equalizing to obtain the desired response curves makes it to have exceptional low phase deviation and artifacts. Shelving with surgical, but musical precision. A smart circuit layout allows for a maximum boost/cut of 10.5 dB in 0.5 dB steps. The main rotary switch sets 1dB steps whilst the 0.5 button adds half a dB to the main reading. The CUT button turns the boost amount into cut. Six strategically selected frequency choices per band are available (8, 10, 12, 15, 20 and 24 Khz on the high shelf, and 470, 360, 220, 110, 60 and 20 Hz on the low shelf). 2 pole high and low pass filters. In order to keep the sub-low and ultra-high frequency content well under control, further high-pass and low-pass filters have been added on dual concentric rotary switches, at 12dB/octave. 5 frequency choices plus OFF are available on each one (10, 12, 18, 22 and 30 Khz on the low-pass, and 160, 82, 47, 20 and 15 Hz on the high-pass). This is where the magic lives. The Symph EQ would have been an awesome sculpting tool just as it has been described above, but it turns into a monster piece with the following 3 additions: - It features the same exclusive Carnhill input transformers made in Oxford found in the Successor. - Its outputs are driven by 73-type Class-A output amplifiers, built with the same Carnhill St´Ives output transformers as the rest of the family. - Most importantly and, here is where the Symph EQ really shines, it has built in Mid Side (M/S) capabilities. M/S Equalizing cannot be rivaled. Nothing comes close to M/S equalizing a mix. It allows the user to process the center and the sides independently. The benefits of such processing are hard to believe. You can brighten your mix without making your vocals sound harsh, or even tighten the stereo-image’s bass content without making your bass or kick sound weak! This are just a few examples of the Symph EQ M/S power! The response of the Side high pass filter has been made elliptical as in the vintage disk cutters for precise frequency response.

The HA-609A is a boutique two channel compressor and limiter based on classic diode bridge designs. With three transformers per channel (by Carnhill/ St. Ives) and a fully discrete, class A signal path, the HA-609A delivers punch, weight, and just the right amount of color to your mixes, buses, or tracks. The HA-609A’s compressor section offers control for threshold, ratio, release, and can be bypassed. In addition to the standard fixed attack time (tailored for program material), the compressor also offers a ‘fast’ attack mode — which excels at catching loud transients on drum buses and other challenging dynamic material. The compressor’s makeup gain is a class A amplifier with transformer-coupled output, inspired by the legendary ‘73 preamp. With an extended threshold range and a new ‘fast attack’ setting, The HA-609A offers classic limiting with an eye towards the modern workflow. The HA609A can perform limiting from subtle peak control to more extreme sculpting, while controlling the fast transients of percussion and program material. The limiter section also features controls for release time, and can be bypassed. The Heritage HA-609A can be stereo linked, or operate in dual mono, and each channel features a true bypass. It utilizes only rotary switches and precision, stepped potentiometers for perfect recall and channel matching. And like all of the products in their Elite range, the HA-609A is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners — all at the Heritage headquarters in Spain.

The OST-8 adat 500 series enclosure is designed for racking any and all 500-series modules and devices, including ‘double wide’ modules and even the most demanding class-A and vacuum tube designs, and connect them to your existing audio interface. It features Heritage Audio’s On Slot Technology, providing maximum protection, filtering, and isolation to each channel. While most 500-series enclosures on the market have a relatively simple power supply design essentially feeding every channel in parallel, each channel of the OST-8 adat enclosure has its own power supply, individually regulated and isolated from the rest. This ensures that every 500-series module installed will perform at its peak potential, and that no ‘power hungry’ or even a faulty module will compromise the performance of another. In addition to reducing interference, many 500-series devices actually exhibit lower self-noise and better performance when racked in the OST-8 adat enclosure, specially mic preamps. The best part is we have incorporated a premium analog to digital converter to send your signals on to your DAW as easily as possible. This high quality, premium ADC is 24Bit and offers selectable internal sampling frequencies variable from 44.1k to 192k in addition to being externally syncable by WordClock. This all takes place using just one ADAT Lightpipe cable. One of the neatest features of the unit is the ability to individually, per channel, decide whether the signal converted and sent to the DAW comes directly from the corresponding input (non-processed signal), after the 500 series module (processed signal) or from an external source. What this allows you to do is send your processed signal out to another processor and then return it to the unit so it can be converted digitally and sent along to your DAW. This can really come in handy if you need a bit of external rack EQ or compression for more control before the digital conversion. This actually means you have 3 selectable sources for each of the eight converters, a seemingly small detail that can really make a big difference when you´re knee deep in the mix or session and don´t have time to spare. This also means that you can use the OST-8 adat as a stand-alone converter and gradually add 500 modules at your convenience to setup your ideal rig. So for those times when all you need is a top-of-the-line analog to digital converter, look no further, you already have it right here. All the inputs and outputs are provided on gold plated XLRs with LINE inputs and outputs also being offered on DB25 connectors for convenience. The alternative 8 External Inputs for the converter are also available on a DB25 connector. Then, of course, are the format specific connectors for ADAT (two of them for SMUX possibilities) and BNC WordClock Input and Output. Another new and exciting feature in the OST-8 adat is the Link feature, allowing each channel to be linked over to the next at the push of a button (via back panel), no patch cables required. As with all Heritage Audio products; the 500 Series OST-8 adat enclosures are built utilizing the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners.

The Heritage Audio HA-81A is a mix of 2 classic consoles. It is a channel strip that combines an all discrete, Class-A 73-style mic preamp with the infamous 81-style equalizer - arguably the most in-demand products for all recording engineers. The mic preamp that meets the demands. The HA-81A’s preamp section is an 80 dB, all discrete Class-A design with Carnhill and St. Ives input and output transformers. To put it simply, it’s an exceptional Heritage Audio take on the infamous 73-style preamplifier.The preamp features gain, output trim, -20db pad, polarity reverse, and +48v phantom power. The best console equalizer ever made. The HA-81’s equalizer section is an exceptionally musical 4 band, inductor-based equalizer with high and low pass filters. Where 3 band equalizers such as the typical 73-style exceed at musicality but may get short of features, the HA-81A EQ equally excels on both. Extreme control over Shelf or Bell response curves on the high and lows, dual Q on both mid bands, with dedicated high and low mid ones, and a range of 30 frequency selections to choose from. Hybrid design. Heritage quality. The Heritage HA-81A utilizes only rotary switches and precision, concentric potentiometers. And like all of the products in our Elite range, the HA-81A is built with the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners — all at the Heritage headquarters in Spain.

The Heritage Audio TUBESESSOR is an optical tube compressor with an absolute sweet, warm and natural dynamic control possible, but also the possibility to spice up the sound up on occasion. Tube compression, especially based on an optical design, is generally considered to be warmer than VCA and FET designs, and it tends to provide a very pleasant, more natural, smoother result. This has made it the preferred choice for seasoned engineers and producers that want to provide a very transparent control over a signal while offering a hint of enhancement but keeping true to the original tone. For this very reason optical tube compressors are usually the first thing one reaches for when dealing with critical vocals and bass signals. The TUBESESSOR is the perfect option for this. Analog excellence is achieved by combining an all tube-based amplification stage with an outstanding UTC A10 input transformer replica by AMI, as well as a custom all-silicon steel output transformer. With an elevated internal operating voltage you can be sure the TUBESESSOR will heat up any signal while also maintaining its character and vibe. No starved plate circuits here! Never has dynamics control been so easily obtainable while at the same time so invisible. Even with generous amounts of gain reduction being applied anything processed with the TUBESESSOR still maintains its clarity and depth. Thanks to the TUBESESSOR´S three unit high front panel you´ll find plenty of room to adjust the large Herchild-style knobs making it a breeze to achieve the desired sound. No cramped spaces here, just plenty of space to easily and quickly adjust the settings to taste. Now, we all know it would not be a Heritage Audio product without our expertise and passion channeled into a couple key features that take the TUBESESSOR to another dimension. First of all, for those times when a bit more texture and bite is called for, there´s nothing better than a little saturation…or maybe a lot. The innovative TUBE SATURATION section takes full advantage of a creamy sounding NOS Raytheon double triode tube to add in just a pinch of aggression or fully transform the signal into something ready for war. It, importantly, works in tandem with the custom output transformer to produce the right harmonic content. There are 4 available settings that vary from CLASSIC, no saturation, all the way to HOT, a heavily treated signal. This feature alone opens up a ton of possibilities for drums and other instruments vastly expanding the TUBESESSOR´S uses. And thanks to Heritage Audio´s use of an audiophile-grade Psvane dual output triode in a totem pole configuration, a solid output stage is guaranteed all while allowing much higher headroom than other tube compressors, whether vintage or modern. Secondly, there are also five internal sidechain filter settings to choose from. This is the exact same filter section that helped the SUCCESSOR obtain its legendary status. Two of the options make sure the compressor is not being unfairly overpowered by lower frequencies and the other three are frequency specific options for extra creativity. Continuously adjustable ATTACK & RELEASE controls in addition to a FIXED mode and a combination of the two will provide all the necessary settings possible, allowing you to mold your signal exactly as you´d like. A huge, attractive custom VU meter for monitoring either Input, Output or Gain Reduction guarantees you´ll always be informed with a clear reading of exactly what is happening. Everything you could possibly require to achieve a top-notch professional recording. As is the case with other tube offerings from Heritage Audio, the company has sourced NOS tubes for a lifetime, making sure your investment is safe and sound.

The MOTORCITY EQualizer is a completely analog, passive EQ with seven accessible frequency points across the tonal spectrum. It is a reproduction of the legendary "MOTORCITY EQ" from the Motown studios and was faithfully recreated based on an unit from the inventory of eight-time Grammy Award winner, producer, mixer and innovative technical genius Michael Brauer. From the 10-gauge hand brushed aluminum face plate, historically accurate control layout including custom molded bakelite knobs, the MOTORCITY Equalizer looks the part. More importantly, the unique passive equalization circuit is identical and fully faithful to the original design, including custom build mil-spec 1960’s tone capacitors and inductors. The Heritage Audio MOTORCITY Equalizer delivers the same unmistakably huge, punchy, and warm signature sound that makes this EQ as classic as the hits it helped create. The MOTORCITY EQualizer has seven accessible frequency points across the tonal spectrum: 50 Hz, 130 Hz, 320 Hz, 800 Hz, 2 kHz, 5kHz and 12,5kHz. Each frequency has a stepped rotary switch capable of a flat response, or up or down up 8db in 1dB increments. The front panel also features a combined in/out/off toggle switch with top hat knob and jewel light power indicator. All rotary switches have easy to read from a distance “General Radio” bakelite style knobs recreated to look exactly like the originals. Finally, it features a master gain control (-8db/+8db) with 1dB increments. The incredibly simple 1960’s accurate back panel features a power supply jack for the external power supply, and an XLR input and output. The sound of the MOTORCITY EQualizer is exactly what you’d expect. It packs a punch without sounding harsh or distorted. The Heritage audio MOTORCITY EQ is not a digital equivalent, not a respectfully close replica and not a more compatible modernized “improvement.” The MOTORCITY EQualizer is nothing more or less than the genuine reproduction of the original, finally made available for the general public.

Standing for DUAL TABLETOP 73, it is in essence a reformatted DMA73.The DTT-73 brings a new flavor to the Heritage Audio line of outboard gear, widening the range of application to On Stage use, portable systems, hotel rooms, On Location recordings, etc. Now musicians are able to give 1073-driven line levels to FOH engineers, using the front panel DI inputs. While on the road they are able to record at the same studio quality level from hotel rooms, etc. Stage microphones can be brought up to line level without using long cable runs. These are just some of the possibilities. Special care has been taken with the internal universal power supply so that no noise has been introduced. The implementation of DI thru jacks allows simultaneous use of instrument amplifiers. A ground lift switch prevents any ground loops introducing hum in the audio when using these. The combination of wood and RAF blue grey steel makes the tabletop units aesthetically stand out in any professional recording environment.

The 73DI ONE is a single channel high-fidelity, transformer-isolated active DI box based on the legendary 73 topology, re-engineered for modern professional audio applications. Designed around a Class A, 3055-driven output stage with a custom silicon steel grain-oriented output transformer, the 73DI ONE delivers the warm, dynamic, and richly saturated tone, known from the iconic vintage 73 preamps. The 73DI ONE adopts the legendary 3-transistor topology circuit of the 73 preamps with a J109 JFET as first transistor to achieve a high 2.2 megohm input impedance and a 2n3055 metal can output transistor to drive the custom-developed silicon steel grain-oriented output transformer. Being a transformer based unit, its output is isolated from the instrument and with the ground lift switch, noise and interference can also be eliminated. An additional 15dB PAD switch helps with hotter instruments and even allows speaker outputs to be plugged into the 73DI ONE. A THRU parallel connection a for forwarding the input signals is also available. All jacks and XLR are gold plated and isolated from chassis. An attractive yet protective extruded aluminum case makes the 73 DI ONE virtually indestructible and totally roadworthy, with all connections recessed for foolproof operation. This meticulously engineered design is what gives the 73 DI ONE its outstanding performance, delivering a rich, dynamic direct sound that fully captures the harmonic complexity of any instrument and even pre-recorded tracks. Ideal for guitars, basses, keyboards, synths, drum machines, and samplers, the 73DI ONE brings out the true voice of every instrument - enhancing passive basses with punch and presence, revealing the full body of a Fender Rhodes, and adding rich saturation to Wurlitzer EPs.
