1INPUT Indicators

Two sets of LED indicators monitor audio signal levels at the inputs A (left) and B (right). When the green SIGNAL indicators are on, the input signals are greater than -40 dB. Below this threshold, the indicators will be off, signifying that the input signals are too low for proper amplification or are disconnected from the system.

When the red CLIP indicators are on, audio signal levels are 2 dB below the maximum clip level. If the input signals exceed this level, distortion will result. When you observe this condition, simply lower the L MIX R (Master) Faders until the CLIP indicators turn off.

2SPEAKER STATUS Indicators

Two sets of LED indicators, OKAY and WARNING, provide visual status of amplified signal levels driving EVO loudspeakers connected to the main outputs, 1A (left) and 2B (right), and the auxiliary outputs, 3A (left) and 4B (right). The indicator states are:
