2.Protect LED Indicators

The CP700 features several types of protection circuitry to prevent damage during turn-on or fault conditions. If any of these LEDs illuminate, one of the various protection features is safeguarding the amplifi er. The output relays will disconnect the speaker loads when the protection circuitry detects a fault condition.

•Loudspeaker Protection - When power is fi rst 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 amplifi er output to the load. The yellow Protect LEDs will illuminate during this power up process.

•Thermal Protection - The CP700 protection circuitry monitors itself for excessive internal operating temperatures. In the event of this circuitry detecting abnormal thermal conditions (blocked cooling fan and high ambient temperatures), the speaker relay will disconnect the speaker load from the amplifi er. Once the internal operating temperature drops back to a safe level, the relay will close, reconnecting the speaker load to the amplifi er.

•Short Circuit Protection - The yellow Protect LEDs will illuminate should the amplifi er 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 amplifi er. The protection circuitry will stay activated until the fault is cleared.

Note: Once the specifi c 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 -26dBv or higher.
