The GQ600 us a precision dual channel 1/3 octave graphic equaliser which provides up to 10dB of boost or cut at 30 centre frequencies between 25Hz and 20kHz. Filter design has been carefully optimised for good interpolation and improved narrow band performance, whilst high quality long-throw 45mm sliders are used for better resolution. The GQ600 also provides excellent noise and distortion performance, with a flat noise figure of better than-98dBm. A shelving HF Trim section is provided, with adjustable gain and frequency allowing fast adjustments to be made to overall high frequency response. This obviates the need for system re-voicing when, for example, changes in humidity or audience size occur. A sweepable high-pass filter offers turnover frequencies of 10Hz to 150Hz and a fixed frequency low-pass filter is also provided for increased H.F. driver protection. This filter is selectable in or out of circuit via jumper links on the main circuit board. Audio inputs and outputs are provided on lockable XLRs and are fully electronically balanced as standard. Optional transformer balancing is also available for both inputs and outputs. Additional features include; relay fail-safe bypass, peak level indicators and optional Perspex security cover. The GQ600 is sturdily constructed from high quality components and undergoes extensive testing and quality control procedures including a minimum 48 hours burn-in period prior to despatch.

The DP648 builds on the legacy of the SIDD, C2, D2 processing, the XTA DP448 and DPA amplifiers. Providing ethernet control of this suite of IIR, FIR and dynamic processing essential for sound system management. The Dante/ AES67 option and flexible routing make it a comprehensive system processor, for overall system management or for traditional loudspeaker management. The DP648 works as a system processor for any audio system, the XTA system scales for more advanced control when partnered with other XTA products. This includes the MX36 console/source switcher, DPA and DNA amplifiers which come with or without dsp. The DP648 is equally suited to FOH racks as a system processor providing overall system management or located in amplifier racks as a more traditional crossover providing stereo 2, 3, 4+ way loudspeaker processing. The extensive XTA preset library makes this even easier. To deliver this precise control the DP648 has the full suite of classical IIR filters, phase, all pass and delay on both inputs and outputs, input dynamic eq and an extensive loudspeaker preset library containing both IIR and FIR setting . The DP648 has full front panel control, PC remote software control by Audiocore Amped edition. PC & MacOS control using globcon XTA MC² Edition. Full or partial locking of front controls is possible when required. Multiple DP648s can be elegantly controlled by fast software grouping, inputs and or outputs can appear in up to 32 groups, making complex systems easy to manage. Grouping is effectively a virtual 32 output processor across compatible amplifiers and processors.
