11. LRS Short Circuit Protection
If an output is shorted (i.e. defective speakers or crossed speaker wires) the LRS will automatically
protect the amplifier. The load will be disconnected by the thermal protection circuitry (output relay
opens) and the amplifier will be shut down. Please remove the short circuit and switch on the amplifier
again to restart the amplifier.
12. DC Voltage Protection
If an amplifier channel detects DC voltage at its output terminals, the output relay will immediately
open to prevent loudspeaker from damage. The Protect LEDs will light up and the LCD display will
show DC Protection and Fault.
13. Subsonic Frequencies
Built-in high pass filtering provides subsonic frequency protection for each channel. In addition a relay
will open if excessive subsonic energy appears at the output.
