Amplifier Indicators
The amplifier in the control enclosure features several LED indicators that are helpful when
trying to diagnose issues with the audio system. There are two sets of LED indicators, one for
each channel. These indicators are described below (LED color is in parentheses).
 Thermal ( Red ): Illuminates when thermal compression begins due to
excessive temperature conditions; TURN OFF AMPLIFIER and allow it
to cool down – if amplifier consistently overheats, it may have a faulty fan
 Clip ( Red ): Illuminates at the threshold of audible distortion;
REDUCE OUTPUT LEVEL!
 -10 ( Green ): Illuminates when the output signal exceeds -10dB below clip
 -20 ( Green ): Illuminates when the output signal exceeds -20dB below clip
 Signal ( Green ): Illuminates when the channel input exceeds -40dBu;
useful for troubleshooting cable runs
 Ready ( Green ): Illuminates when the amplifier is ready to produce audio
Refer to amplifier manual (listed in Appendix B) for more information.
