ZAPCO HDSP-V Series - HDSP-Z16V AD-16A

The ZAPCO HDSP-Z16 V AD-16A DSP sound processor of the HDSP-V Series is a high-end 16-channel DSP, which  uses 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 delivery.

The HDSP-Z16 V is the best hardware Zapco has ever built, and the numbers prove it. Even though the HDSP is made up 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 excellent. 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 was created that Zapco believes will go down in Zapco history and set new standards for what is possible in audio reproduction. The numbers are the 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 a testament to the accuracy with which the layout was created. But of course, background noise and crosstalk are not the only numbers that matter in audio equipment. All other values ​​are not as spectacular as -140 dB noise floor, but are still excellent.

The digital inputs have 114 dB A-weighted signal/noise and the analog 109 dB at rated power. We kept the output voltage at 4 volts to avoid additional distortion from the analog pre-amplification. The distortion of the analog and digital inputs is less than 0.001% at 4 volts output and less than 0.00175% at 1 volt output. 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, it is an HD player that works at 24 bit/192 KHz and has an 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 power of 912 MHz.

Then there is a microprocessor that only controls the player and does not have to do any other heavy computing like a computer might do. So you could say it is a DSP within a DSP, or the most sophisticated DSP you can get on board an HD player. The player has its own browser that starts working immediately when you plug in the USB memory stick. It can read all formats up to 24 bit/192 KHz, compressed or uncompressed, and the 3" touchscreen display lets you control all functions through 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 easy and intuitive for everyone to use, but that doesn't mean it's any less sophisticated. It is divided into three main areas: the front, the rear and the effects. The front seat sound tuning and the rear seat sound tuning offer two different and independent autotunings, as well as the effects tuning.On the main screen you can see all 16 channels with all settings at once. It is an overview screen for the fine adjustments made channel by channel, while special pages for each main function allow you to focus on one function and conveniently adjust all channels together. Auto-tuning guides you through the different phases, 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 adjustment of all functions with maximum adjustment 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 up the crossover easy and straightforward. You can select the desired filter style and slope (from 6dB~48dB)
• Delay & Polarity - This page allows you to adjust the signal delay for each channel. You can also adjust the polarity of each speaker to ensure they are all in phase.
• AP/Phase - The HDSP V's graphical user interface uses all-pass filters to give you complete control over phase. There is an all-pass filter for each channel that allows you to set the target frequency for a phase shift and the amount of phase shift between 1° and 359°.
• VSEQ - The VSEQ allows you to seamlessly correct the factory bass roll-off with a gradual change. The VSEQ restores frequencies to the same level 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 used at any frequency and the quality (Q) of each filter is variable from 0.5 to 15. The filters allow a gain of +6 dB to -15 dB.
