Zapco DSP-Z8 IV AT digital sound processor DSP.

Zapco DSP-Z8 IV AT (IV series) the Digital Signal Processor with autoTune (8-channel). 

The Digital Signal Processor with 8 inputs and 8 outputs. 
It was designed to bring true audiophile sound quality to an affordable DSP. 
The DSP-Z8 IV provided sound quality superior to units costing even twice as much. 
But, as we have always said, and always will say, “We believe we can still do better”. 
The DSP-IV series (except the ADSP-Z12 IV-10A and ADSP-Z16 IV-12A) processors give you automatic Calibration for: 
Equalization, Phase, and Signal Delay, when you add the optional calibrated tuning microphone. 
You can choose which function of functions you wish to have the system calibrate and you can choose which channels you wish to include in the calibration. 
In the Graph area you can see what the system is doing by looking at the Speaker curves and/or the Equalization curves, and you can turn the target curve on or off. 
Calibrating all channels for all functions can typically 5 to 10 minutes to do automatically what you might spend several hours doing. 

Of courseit is the human ear that will always be the final judge, but the auto tuning puts you at the point where you can do just the final tweaks and sit back and enjoy the music.
