91.Product is in protection mode due to high temperature or malfunction.2.Wrong wiring or connectionsTROUBLESHOOTINGNo outputAll wires are connectedproperly but there is noaudio output.Cause1.No power or wrong connection2.Fuse is blown3.Volume is turned off4.No input signalAlarm sounds whenpower is turned on1.Overloading or short circuit2.Voltage is not stable, too high or lowProblemsMUTE FUNCTIONOPERATION 1. TEL has priority over all inputs.2. MIC 1 is second priority, adjusting the mute level can override all other input signals except for the TEL signal. You can choose only two of the four output connectors towork together. If voltage is 70V/100V the speakers musthave a transformer, make sure the total power wattage ofspeaker is 15% less than the power wattage of amplifier.
