The DSP-IV AT Series with AutoTune

Some years ago, Zapco introduced the new DSP-Z8 IV signal processor. 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. The DSP-Z8 IV has been a true giant killer. But, as we have always said, and always will say, “We believe we can still do better”. We firstly presented the DSP-Z8 IV II, and this year we present the Zapco DSP-Z8 IV AT and the ADSP-Z8 IV-6AT Amplifier. What’s new with the Series IV AT? New features and new control. The sharp look matching the Black and Copper theme of the AP amplifiers is only the beginning.

You can only be as good as your source material, and the DSP-Z8 IV AT series greatly expands your potential for the best possible source material. The new coaxial and optical inputs accept the digital signal from your head unit or from a portable HD player. The DSP-IV AT units also have a port for HD Bluetooth streaming (with the optional HD-BT module). An interactive digital port will expand your options even more. The port accepts the control input from the included Dash Remote so you can change input source, select your song, control the master volume and even control the output of your system’s bass amps. The new ADSP-Z8 IV-6AT amplifier has now 2 RCA outputs to feed the mono amp. About the GUI, the added Advanced menu also has a Mixing Set and an AutoTune function, when you add the optional tuning microphone
