RACK MOUNTING EARS
These mounting holes are provided on each front mounting ear.
2.
3-POSITION AC POWER SWITCH
A 3-position switch is on the front panel. Sequential remote turn-on capability is a standard
feature. With the switch pushed towards the outside position, the amplifier is ON. The middle
position is OFF, and the inside position is marked STANDBY. When switched to STANDBY,
the amplifier may be activated by the sequential turn-on circuit. See the section on
SEQUENTIAL TURN-ON / TURN-OFF for more information.
3.
POWER LED
The POWER LED illuminates when the amplifier is turned on.
4.
SIGNAL LED
Each channel has a SIGNAL LED that illuminates when the amplifier output exceeds 1 volt.
5.
CLIP LED
Each channel has a CLIP LED that illuminates at the clipping point, and indicates that internal
circuitry is reducing amplifier gain to allow full power. See the section on PROTECTION
FEATURES for more information.
6.
LFC
LED
™
Each channel has a LFC (Load Fault Correction) LED. This LED illuminates when the
amplifier channel detects an abnormal load condition. Internal circuitry will instantaneously
reduce the channel gain to allow the amplifier to operate at a safe level into the abnormal
load. See the section on PROTECTION FEATURES for more information.
7.
PROTECT LED
If the amplifier has just been turned on or has detected a fault condition, the speaker output
relays will open, illuminating this LED.
