. Status Indicators
The Status LED is a multi-purpose indicator that lights in three colors to show status. One for each channel.
•
Green - Amplifier is on and operating normally.
•
Amber - Amplifier is in low-power consumption Sleep Mode.
•
Red - Amplifier has protected itself due to a fault condition.
2. Signal Indicators
Illuminates green when signal is present at the input. One for each channel.
3. Clip/Limit Indicators
This indicator illuminates amber when there are excessive signal levels or very low impedance output loads. A
built-in Clip/Limiting circuit activates and reduces input signal levels when output distortion exceeds a few per-
cent or when the output load draws too much current. One for each channel.
4. Power Switch/Circuit Breaker
Controls AC power to the amplifier and also works as a circuit breaker. If the circuit breaker trips, push it to
the OFF position (O) and then to the ON position ( l ).
5. Fan Grilles
Removable fan grilles are provided to allow access to the dust filters for cleaning.
6. Volume Controls
Detented (40 position) knobs are recessed for protection from mechanical damage. One for each channel.
Knob Cover (not shown - see #4 on page 4)
