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.
