Rossman AMP2x75 amplifier


ISSUE: frequent “clicking” sound heard over speakers

RESOLUTION: classrooms with this model amplifier may experience this clicking, which is an input-sensing relay within the unit opening and closing.  To resolve, change the “ON/AUTO” switch on the rear control panel from AUTO to ON.  This will leave the amp powered on, without the input sensing engaged, and should resolve the clicking.  This switch is the bottom-most switch on the rear panel, directly above the RCA input jacks.
