Status LED’s / Protection Circuitry
There are two status indicator lights on the wiring end panel of the amplifier.
1. “POWER” (Green): Lights to indicate that the amplifier is turned on and
operating normally.
2. “PROTECT” (Red): Lights to indicate the amplifier’s protection circuitry
has been triggered to prevent product failure due to any conditions
noted in the chart below. When a protection mode is activated, the
amplifier will shut down to protect its circuitry. For Thermal Protection,
Over Current and Short Circuit conditions, the amplifier will resume
normal operation once the problem is corrected, with the “Protect” LED
turning off. For Over Voltage conditions, the amplifier must be turned
off/on to return to normal operation. Note: connecting the speaker
outputs to impedances lower than 2 ohms (4 ohms bridged) will also
cause this protection mode to activate.
