Safety
• As a precaution, it is recommended to disconnect the vehicles battery before mounting the DSP. (Note: For
new vehicles, disconnecting the battery might cause various errors in your vehicle´s electric system that can
be cleared only by authorized service partners of your vehicle´s manufacturer! Please ask your service
partner first before disconnecting the battery!)
• The p ower supply wire (+12 V) has to be protected within max. 20 cm / 8” by a main fuse holder with a
fuse value matching the recommendation for your amplifier
(Note: If there is more than one DSP connected using this power wire, the main fuse value must be equal to
the sum of the recommended fuses of all connected devices. However, make sure the diameter of your
power wire will be sufficient for the required current!)
• If necessary, replace a defective fuse by a fuse with identical quality and value
• Never drill a hole to the vehicle´s gas tank or brake lines, to wirings or any other important vehicle parts!
• Never pass wires over sharp edges or vehicle parts to avoid any kind of damage
• Keep the wiring away from the antenna and electronic devices contributing to radio reception
• Lay the power supply wiring always separated from spea ker wiring to avoid disturbance

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 ea ch outp ut 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.
App control & music streaming
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.

• To avoid heat build-up, sufficient air supply for cooling must be provided. Never cover the surface of the
heatsink entirely.
• The DSP unit should NEVER be mounted onto a vibrating part or surface such as a subwoofer enclosure.
This might lead to malfunction due to loosened electrical parts inside the amplifier.

Using the line input (RCA), a remote wire can be connected to turn on the DSP unit.
In this case, set the TURN-ON switch to the REM position. Setting the switch to the
SPK position activates the auto-on function, in that case a remote wire is
superfluous.
