FADE-IN PROTECTION

This feature operates every time the amplifier is turned on, or after a protect condition. During turn on, the amplifier goes into protect mode and leaves the speaker load disconnected until the amplifier determines that the operating status is normal. The Fade-In circuit attenuates the signal during the initial turn on or protect operation. After relay release, channel gain gradually increases to the attenuator setting to avoid unnecessary stress on the loudspeakers.

THERMAL PROTECTION

If the heatsink or power transformer reaches an abnormally high temperature, the amplifier will protect itself by disconnecting the speaker load until the amplifier returns to a normal temperature. During this time, the PROTECT LED will illuminate, and the cooling fan will operate at maximum speed.

SHORT CIRCUIT

If an output is shorted, the LFC, speaker relay and thermal circuits will automatically protect the amplifier. The LFC circuit senses the short circuit as an abnormal load condition and reduces the channel gain to a safe level for the load. In extreme or severe conditions, the speaker relays will disconnect the load and initiate a power-on start-up sequence.

DC VOLTAGE PROTECTION

If an amplifier channel detects DC voltage or subsonic signals at its output terminals, the speaker relay will immediately open to prevent loudspeaker damage. The PROTECT LED will illuminate as notification of this condition.

SEQUENTIAL TURN-ON / TURN-OFF

The ICASeries comes standard with remote sequential turn-on. The amplifier front power switch is set to STANDBY. An external direct plug-in power supply unit providing a nominal voltage between 12 to 24 volts DC must be applied to the 4-pin plugable terminal on the rear panel. The ENABLE OUT is connected to the ENABLE IN of the next amplifier. ICA Series amplifiers are bussed or “daisy chained” together in parallel and connected to the DC supply by connecting all 24 V DC+ terminals together and all COMMON terminals together. The first amplifier in the chain requires an SPST closure between its 24 V DC+ terminal and ENABLE OUT terminal to initiate the power turn- on sequence and keep the amplifiers in the chain powered on.
