Zapco HDSP-Z8 V P192 PAD-A 8-Channel Digital Sound Processor with HD Player

The HDSP-Z8 V is the best hardware that Zapco has ever built, and the numbers attest to that. Although the HDSP is composed of 18 individual pieces put together in a modular version that is easy to adapt or update according to your needs, the background noise and the crosstalk numbers are superb. The end result surpassed even the expectations of the designers and engineers who built it. It took almost three years, but eventually came this unique piece of hardware that we believe will remain in the history of Zapco and set new standards for what is possible in audio reproduction. The numbers are the proof of the design, for example -140 dB of background noise and  -115 dB of crosstalk. For a 16-channel device, crosstalk at -115 dB (average around 1 KHz) is proof of the accuracy with which the layout was made. But of course, background noise and crosstalk are not the only numbers that matter in audio devices. All the others, while not so spectacular as -140 dB floor noise, are superb. The digital inputs have 114 dB of A weighted signal/noise and the analog ones 109 dB at rated output. We kept the output voltage at 4 Volts to avoid added distortion of analog preamplification. Distortion of analog and digital inputs are lower than 0.001% at 4 Volt output and lower than 0.00175% at 1 Volt output. The HDSP-V power supply continues to work down to 6  Volts to solve the problem of cars that have the stop-start ignition system. The main processor is a dual core 456 + 456 MHz, 8 and16 channels solution have a 192 and 96 KHz sampling rate and the converters are new 32 bit/784 KHz devices from AKM. Very importantly, it is an HD Player that works at 24 bit/192 KHz integrated with DSP. There is no connection between the Player and the DSP, no PCB, no connectors, no cables. Player and DSP are integrated in one dual core chipset that has a total power of 912 MHz. Then there is a microprocessor that controls only the Player and does not have to do other heavy computational work like can happen, for example, with a computer. So, you can say it is DSP within a DSP, or the most sophisticated DSP existing  with a on board HD Player. The player has a dedicated browser that starts to work immediately when you insert the USB memory stick. It can read all formats up to 24 bit/192 KHz, compressed or not compressed, and from the 3” touch screen display, you can control all the functions using 3 different levels of folders. The dash board that controls the Player also controls minor DSP functions and can manage up to 10 tuning presets with instantaneous switching of one to another for A/B comparison.
