ZAPCO HDSP-V Series - HDSP-Z16 V AD-16A

The ZAPCO HDSP-Z16 V AD-16A DSP sound processor of the HDSP-V series is a high-end 16-channel DSP that utilizes the most advanced ADC and DAC converters for maximum sound quality, achieving an extremely high signal-to-noise ratio of 109-120dB. A remote control for controlling the DSP is included in the scope of delivery.

The HDSP-Z16 V is the best hardware Zapco has ever built, and the numbers prove it. Although the HDSP consists of 18 individual parts assembled in a modular version that can be easily customized or upgraded as needed, the noise floor and crosstalk levels are outstanding. The end result exceeded even the expectations of the designers and engineers who built it. It took almost three years, but finally this unique piece of hardware has emerged that Zapco believes will go down in Zapco history and set new standards for what is possible in audio reproduction. The numbers are proof of the design, for example -140 dB background noise and -115 dB crosstalk. For a 16-channel device, a crosstalk of -115 dB (average at 1 KHz) is proof of the accuracy with which the layout has been created. But of course, background noise and crosstalk are not the only numbers that matter in audio equipment. All other values may not be as spectacular as -140 dB background noise, but they are still excellent.

The digital inputs have 114 dB A-weighted signal/noise and the analog 109 dB at nominal power. We have kept the output voltage at 4 volts to avoid additional distortion from the analog preamplification. The distortion of the analog and digital inputs is less than 0.001% at 4 volts output voltage and less than 0.00175% at 1 volt output voltage. The HDSP-V power supply works down to 6 volts to solve the problem of cars with stop-start ignition systems. The main processor is a dual-core 456 + 456 MHz, the 8 and 16 channel solutions have a sampling rate of 192 and 96 KHz and the converters are new 32-bit/784 KHz devices from AKM. Very importantly, this is a 24-bit/192 KHz HD player with integrated DSP. There is no connection between the player and the DSP, no circuit board, no connectors, no cables. The player and DSP are integrated in a dual-core chipset that has a total performance of 912 MHz.

Then there's a microprocessor that only controls the player and doesn't have to perform any other heavy computing tasks, as can happen with a computer, for example. So you could say it's a DSP within a DSP, or the most sophisticated DSP available with an HD player on board. The player has its own browser that starts working as soon as you insert the USB memory stick. It can read all formats up to 24 bit/192 KHz, compressed or uncompressed, and the 3-inch touchscreen display allows you to control all functions via 3 different folder levels. The dashboard that controls the player also controls smaller DSP functions and can manage up to 10 tuning presets, from which you can instantly switch to another for A/B comparison.

• The DSP-V user interface has been designed to be simple and intuitive for anyone to use. However, this does not mean that it is any less sophisticated. It is divided into three main areas: the front, the rear and the effects. Tuning the sound of the front seats and the sound of the rear seats offers two different and independent auto-tunings as well as tuning the effects. On the main screen you can see all 16 channels with all settings at the same time. It is an overview screen for the fine adjustments made channel by channel, while dedicated pages for each main function allow you to focus on one function and conveniently adjust all channels together. Auto-tuning guides you through the various stages, from correctly connecting all components to setting the amplifier and DSP levels to achieve the best possible sound quality. For experienced tuners, there is also a manual setting of all functions with maximum setting resolution.
• I/O matrix - The input/output (I/O) matrix allows the manual tuner to determine which input is used for each output.
• Crossover - The crossover page of the V Series DSP makes setting the crossover simple and clear. You can select the desired filter style and slope (from 6dB~48dB)
• Delay & Polarity - On this page you can set the signal delay for each channel. You can also set the polarity of each speaker to make sure they are all in phase.
• AP/Phase - The graphical user interface of the HDSP V uses all-pass filters to give you complete control over the phase. For each channel there is an all-pass filter that allows you to set the target frequency for a phase shift and the amount of phase shift between 1° and 359°.
• VSEQ - With the VSEQ, you can seamlessly correct the factory bass drop with a graduated change. The VSEQ restores the frequencies to the same volume as they were removed from the factory by digitally reading when the change begins and when it ends.
• Equalizer The main page contains the equalizer graphic. Each of channels 1~12 has 30 parametric filters and channels 13~16 have 6 parametric filters each. The filters can be applied at any frequency and the Q of each filter is variable from 0.5 to 15. The filters allow a gain of +6 dB to -15 dB.
