The RAM1000 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 RAM1000 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 RAM1000 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 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 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.

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 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.

Heritage Audio decided to meet the demands of many musicians, producers and engineers and offer and all-in-one package with the Súper 8 to get eight high-quality signals recorded into your DAW with the absolute minimum of fuss. For the first time ever Heritage Audio is introducing a package with eight of our famous 73 style preamps all in just one 2 rack space unit. So this piece is stuffed with all the goodies you´d expect including exclusively designed Carnhill transformers on the Inputs and Outputs and Tantalum capacitors to make sure you get all the juice, vibe and feel from that golden era all while dishing out a very generous 80dB of gain. The Súper 8 Preamps are complete with the features you´ve come to expect. Each channel has a button to activate the 48v Phantom power, a LINE button to prepare the input for Line Level signals, a PHASE button to flip it 180º, and a LoCut button to produce a -3db cut at 80Hz. The first two channels are also equipped with a Lo-Z button which will change the input impedance from 1200Ohm to 300Ohm, a PAD button to reduce the input -20db, our famous JFET D.I. as well as a fully sweepable LoCut filter. Everything you could possibly ask for in a professional preamp. So there are eight channels of our famous high-quality 3 Stage Class A fully transformer balanced analog input and outputs, always available. And what might be the best part of it all, 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. Three different digital output options are available; ADAT/SMUX, SPDIF and AES/EBU to make sure all of your needs are taken care of. Now it´s possible to turn your wallet-friendly audio interface into a quality, professional recording rig. 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(preamp) or from an external source. What this allows you to do is send your preamped signal out to a 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 EQ or compression for more control before the digital conversion. This actually means you have 2 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. Another great possibility is the option to also use the Súper 8 as a stand-alone converter. 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 returns 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, as well as a 9 PIN connector to access either the SPDIF or the AES/EBU conversion.

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 TABLETOP 73, it is in essence a reformatted DMA73.The TT-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.

The OST-4 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-4 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-4 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 (on back panel), no patch cables required! As with all Heritage Audio products; the 500 Series OST-4 V2.0 enclosures are built utilizing the most cutting edge methods in manufacturing and design, without ever compromising audio quality or cutting corners — all at the Heritage Audio headquarters in Spain.

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 dual channel HA73X2 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 HA73X2 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. The HA73X2 offers two channels of classic sound in one rack unit for stereo recordings or two single sources.

The DMA-73 is a dual-channel mic pre with a sound and circuitry almost identical to that of the legendary Neve 1073. Perfect for old ribbon mics, the 80dB microphone preamp re-creates faithfully that vintage sound. The Line mode with 50dB of gain allows for reamping of prerecorded tracks and it´s perfect for adding some class A color to lifeless recordings. Two XLR mic and line inputs on the rear and two ultra-high-impedance J-Fet direct inputs and a 20dB pad to avoid overloading will handle any source. The DMA-73 is packed in a standard 19” howsing with an external low nois powersupply.
