1. Power Switch
This rocker switch supplies power to the amplifier. A red LED located above the power
switch will illuminate when the amplifier is switched on.
2. Protect LED Indicators
The amplifier features several types of protection circuitry to prevent damage during
power-up or fault conditions. If any of these LEDs illuminate, one of the various protection
features is safeguarding the amplifier. The output relays will disconnect the speaker loads when
the protection circuitry detects a fault condition.
• Loudspeaker Protection - When power is first applied, the speaker protection relay is
open, preventing transients from reaching the loudspeakers. After the internal power
supplies have stabilized, the relay will close, connecting the amplifier output to the load.
The yellow Protect LEDs will illuminate during this power-up process.
• Thermal Protection - The amplifier protection circuitry monitors itself for excessive
internal operating temperatures. In the event this circuitry detects abnormal thermal
conditions (blocked cooling fan or high ambient temperatures), the speaker relay
will disconnect the speaker load from the amplifier. Once the internal operating
temperature drops back to a safe level, the relay will close, reconnecting the speaker load
to the amplifier.
• Short Circuit Protection - The yellow Protect LEDs will illuminate should the amplifier
detect a short circuit on the attached speaker load or if the load impedance is too low.
When this condition is detected, the internal speaker relays will open up, disconnecting
the load from the amplifier. The protection circuitry will stay activated until the fault is
cleared.
Note: Once the specific fault has been corrected, the power may have to be cycled to reset the
protection circuitry.
3. Signal "Status" LED Indicator
The green "Status" LEDs will illuminate once the input signal has reached -26 dBV or higher.
