DIAGNOSTIC LED’S

The Red LED indicates that the amplifier is on.

The Yellow LED indicates that an over-current condition (low imped- ance) exist and will turn the amp’s output power down to maintain unin- terrupted operation. The Yellow LED will light if a speaker load falls below the M Series’ 2Ω rating and/or a speaker lead / speaker voice coil is shorted.

The Orange LED indicates that an over-heating condition exists and will turn the amp’s output power down to maintain uninterrupted operation. The Orange LED will light if the heatsink temperature exceeds rated spec due to poor ventilation.
