Ground Zero GZDSP 4-8XII

Description

The Ground Zero GZDSP 4-8XII is an excellent choice for a DSP processor to integrate with a car’s factory head unit.

It features 4 input channels, available as both line-level and speaker-level inputs, which can be used as two or four channels according to your setup.

On the output side, the unit provides 8 configurable channels. Each channel’s parameters can be individually set, allowing for flexible system designs such as a full 4-way system with all crossovers and delays, an active 2-way front system with subwoofer and rear speakers, or any combination supported by the 8 outputs.

When using speaker-level inputs, the unit automatically activates upon detecting a signal, eliminating the need for a separate remote turn-on from the head unit. Additionally, the DSP can pass turn-on voltage to connected amplifiers, simplifying integration with factory systems.

Optional accessories:

• GZDSP BT-STICK for wireless audio streaming directly to the processor

• Wired remote control GZDSP REM 4-8XII
