Control Functions:
- LPF (Low Pass Filter): Adjusts the upper frequency limit for the subwoofer channel.
- Boost: Controls the bass boost level for enhanced low-frequency output.
- Subsonic: Filters out ultra-low frequencies that are inaudible and can damage subwoofers.
- Phase: Adjusts the phase of the subwoofer output (0° or 180°) to optimize bass integration with other speakers.
- Gain: Matches the amplifier's input sensitivity to the output voltage of your head unit. Use the Clip detection light for optimal setting.
- Clip Indicator: Illuminates when the input signal is clipping, indicating distortion. Adjust gain down until the light no longer illuminates during peak playback.
The external bass control remote (Figure 2) provides convenient, on-the-fly adjustment of the subwoofer level without needing to access the amplifier directly.
