The GZDSP 6-10SQ is a digital signal processor that can significantly improve the sound quality of a car
music system under certain conditions. The basis for this is a 32-bit SigmaDSP in conjunction with six 32-bit
analog-to-digital and ten digital-to-analog converters. Thanks to the free combination of up to 6 input
channels and a 31-band equalizer for each output channel, the GZDSP 6-10SQ can be integrated into almost
any factory system. The source-specific, 7-band input equalizer also helps optimize the input signal.
In addition to the 6 analog high- and low-level connections, the GZDSP 6-10SQ also offers an optical, digital
and BT interface.

To use your mobile device controlling the unit and changing the adjustments, please install the GROUND ZERO
GZDSP 6-10SQ control app on your device (Android / iOS) and connect the separately available music
streaming interface. Check the web page for further information and to download the app´s owner´s manual.
