The amplifier includes LED indicators to provide operational status:
- Optimized Signal Flow LEDs: Indicate when input and output signals are at optimal levels.
- MILC Clip Detection LED: Illuminates when the input signal is clipping, indicating potential distortion. Reduce the input level if this LED is active.
- Apsaugos šviesos diodas: Šviečia, jei amplifier detects a fault condition (e.g., overheating, short circuit).
7.3 Optional ACR-3 Remote Control
An optional ACR-3 wired remote controller can be connected to the amplifier. This remote allows for control over source selection, output levels, and recalling saved DSP presets from the driver's seat.
