Fault Protection |
Over Current: Protects each channel individually against an excessive speaker load or shorted speaker line;
DC Offset: Protects each channel and speaker line against DC voltages sensed at each output;
Over Temperature: Protects the amplifier power supply and each channel against overheating due to poor ventilation or excessive temperature;
Under Voltage: Protects the amplifier if the internal power supply voltage is below tolerance due to excessive output levels or insufficient line voltage;
Note: All faults report to the control system, and indicate on the front panel and in the software tool. |
Output Relays |
Disconnects the speaker line at each output under fault conditions, and during startup and shutdown |
Audio Ramp |
Ramps each channel’s audio level up to its last used setting after the corresponding output relay has closed following startup or fault recovery; ramp time 130 milliseconds |
