AMPLIFIER STATUS INDICATOR LIGHTS &
PROTECTION CIRCUITRY
There are two status indicator lights on the
control panel of the amplifier.
1) "Power" (Green): lights to indicate that the
amplifier is turned on and operating normally.
Located at the far left of the control panel.
2) "Protect" (Red): Indicates that the amplifier
protection circuitry has been activated
to prevent product failure due to thermal
overload, short-circuit or a dangerously
low impedance connected to the amplifier
outputs. Connecting the speaker outputs
to an impedance lower than 2 ohms stereo
(4 ohms bridged) will cause this protection
mode to activate. When this protection mode
is activated, the amplifier will shut down to
protect its circuitry. When the problem is
corrected, the amplifier will return to normal
operation and the "Protect" LED will shut off.
