1. HANDLES
These are provided for easy transporting and installing into equipment enclosures or racks.
2. LEVEL CONTROL
This control adjusts the level (amplitude) of the input signal for each channel. In stereo or parallel mode the
knobs will determine the signal level independently for each channel. In the bridge mono mode channel 1 will
be turned fully to the right and channel 2 will be turned right only as needed to achieve the desired signal level.
3. LEVEL INDICATOR
These indicators should illuminate during normal operation when there is an output signal.
4. CLIP LIMITER INDICATOR
This warns of a problem when illuminated. Reduce the LEVEL of the device which supplies signal to the
amplifier or reduce the LEVEL control(s) on the amplifier. This should not be continuously illuminated during
normal operation, but may flash occasionally.
5. PROTECTION INDICATOR
This warns of a problem in the system when illuminated. Reduce the volume and look for problems. It is
possible that the amplifier is too hot or the speaker impedance is too low. This should not be illuminated
during normal operation.
6. MODE INDICATOR
This indicates the operating mode based on the position of the MODE selector switch located on the rear panel.
7. POWER INDICATOR
This confirms the amplifier is switched ON and receiving AC mains POWER when illuminated.
8. POWER SWITCH
The position of this switch determines whether the AC mains power is ON or OFF. The power-on status is
confirmed by the illuminated power indicator. Amplifiers are always the last item in a system to be turned on.
It is generally a good idea to reduce the level controls before applying AC mains power.
