DSP processor Zapco DSP-Z8 IV AT

DSP processor Zapco DSP-Z8 IV AT

Many years ago, Zapco introduced their DSP-Z8 IV DSP processor. It was designed to bring true audiophile sound quality to an affordable DSP. The Zapco DSP-Z8 IV was a giant killer, delivering sound quality better than units costing twice as much. But as Zapco has always said and will always say, "We believe we can do better". First introduced in 2018 was the updated DSP-Z8 IV II series, which brought a number of improvements, and in 2022 we saw the all-new Zapco DSP-Z8 IV AT model series, which includes two new DSP processors, two DSP processor amplifiers and a digital monobloc. And what's new with the IV AT series? New features, new controls and of course even better sound. The unified look of the Black and Copper theme of the Zapco AP Series audiophile amplifiers is just the beginning.

New features of the DSP processor Zapco DSP-Z8 IV AT

Compared to its predecessor, the DSP processor Zapco DSP-Z8 IV AT has improved by two RCA inputs and at the same time by two high-level inputs. In total, it will offer 8 RCA inputs and 8 hi-level inputs. Also new is the option to set the level of the input signal, improved PC software, the possibility of automatic calibration using an optional microphone, and especially the optional Bluetooth module for streaming music in Hi-Res quality. Also new is the remote control, which will allow you to change the input source, control the main volume or amplifier output for the subwoofer and even switch songs when playing music from, for example, a mobile application.

Enhanced PC software

The new DSP-Z8 IV AT DSP processor gives you the great sound and features of the Series IV II and adds a coaxial digital input as well as an optical digital input and Bluetooth streaming capability. However, the PC software also saw several improvements. The drop-down menus now allow you to name each output channel to match your system settings. The added Advanced menu also includes new Mixing Set and AutoTune features. The new DSP-Z8 IV AT gives you more options for input selection. You can have up to 8 input channels which you can instantly set up simply by selecting 2-Ch, 4-Ch, 6-Ch or 8-Ch in the inputs section on the front. If you need to sum the channels of the factory stereo to get the full range of the input, just click SUM and the system will do it all for you. But if your system is more complex, you also have the option to go into the Advanced menu and use Mixing Set to manually assign each channel exactly the amount of input from each input channel that will work best for your particular audio setup.

Automatic sound calibration

DSP IV AT series processors now give you automatic calibration for signal EQ, phase and delay, when you purchase the optional Zapco calibrated microphone. You can choose which function you want the system to calibrate, as well as which channels you want to include in the calibration. In the graph area you can see how the system is currently working and you can also look at the equalization curves of the speakers. Calibration of all channels within all functions is done automatically within 5 to 10 minutes, saving you several hours of time. Of course, the human ear will always be the final judge, but auto-tune will get you to the point where you can just make the final adjustments and enjoy the music.
