B Indicators Indicates the operating status of each of the channels and warns of possible
malfunction. There are 5 indicators for each channel:
• ACL (automatic clip limiting) - indicates clipping. If the light is flashing
quickly and intermittently, the channel is at the clip threshold. Gain
reduction is automatically employed to prevent severely clipped
waveforms from reaching the loudspeakers.
•
SIG (signal) - indicates that an output signal of 4 volts RMS or more (0.1
volt or more at the input with 0 dB attenuation and standard x 40 voltage
gain) is being produced by the channel. The signal is reaching and being
amplified by the amplifier.
• TEMP (temperature) - indicates an unstable thermal condition. The
amplifier protection will activate and shut down the affected channel. The
light will remain illuminated until a safe operating temperature is
achieved.
•
DC (direct current) - indicates abnormal operating conditions. The light
illuminates when conditions arise that will damage the loudspeaker driven
by that channel. The amplifier automatically attempts to restart to correct
the condition. If the amplifier does not return to a normal operating
status, contact your local authorized service center.
• ACTIVE - indicates that the channel is operational. The light illuminates
under normal operation and remains on, even when the channel is in ACL
gain reduction. If the light is off, there is no signal at the output
connectors.
C AC Power Switch Turns the power on and off. This is a combination magnetic circuit breaker and
switch.
D Rack Mounting Ears Provides mounting holes for rack installation.
Rear Panel
If the PARALLEL or BRIDGE input mode is selected, the signal input to channel A of
the power amp is also available as an output on the channel B input connector. This
allows you to patch input signals between multiple amplifiers.
Letter Component Description
A
AC Power Inlet Provides AC power to the amplifier. Connect the IEC line cord to this connector to
provide power to the amplifier.
B Outputs Provides the connecting and bridge outputs:
