Input Signal Level Meter (green)
The measurement range is from 0dBFS to –40dBFS with 0.5dB resolution. Each audio channel has the following monitors:
• Switched Audio Input: This meter shows only the switched (selected) audio input after the Input Audio Router.
• Clip Indicator
• Peak + RMS levels
Output Signal Level Meter (blue)
The measurement range is from 0 dB to –40 dB with 0.5 dB resolution. The monitors are scaled so that 0 dB is referenced to the full rated output voltage of the amplifier.
The wider left meter is rms and the right meter is peak for each channel. An output clip indicator is provided.
Indicators
• Temp: Lights if the temperature of the amplifier is too high and the amplifier is near shutdown.
Green: Thermal headroom used up is less than 59%.
Yellow: Thermal headroom used up is 60-80%.
Red: Thermal headroom used up is more than 81%.
• Limit: Lights when the amplifier signal is being limited.
• Load: Lights when the load impedance is out of range.
• Ready: Lights when the amplifier is on and ready to supply power.
• Fault: Lights when the amplifier is in a fault mode service may be required.
