5.3 Initial Configuration

After all physical connections are made, connect the H8-DSP-DRC to a computer via USB. Install the dedicated HERTZ DSP software to access and configure the processor's settings. This software allows for detailed adjustments of crossovers, equalization, time alignment, and more.

• Input Level Adjustment: Use the 'IN level' potentiometers on the unit to match the input sensitivity to your source unit's output. The 'CLIP' indicator will illuminate if the input signal is too high.
• Speaker Turn On: Set the 'SPEAKER TURN ON' switch to 'ON' for automatic remote turn-on or 'OFF' if using a dedicated remote wire.
• DE-EQ SET: This switch is used for de-equalization settings, typically for integrating with factory head units. Refer to the software manual for specific usage.

6. Operating
