Damage caused by connecting the amplifier to improper AC voltage is not covered by the three-year US warra nty.Make sure the power switch is off before making any in put or output connections.It is always a good idea to have the gain controls turned down during power-up to preve nt speaker damage if there is a high sig nal level at the in puts.Figure 1 3-pin XLR-type conn ectorsCONNECTING INPUTSIn put connections are made via eitherthe 3-pin XLR-type connectors (Figure 1) or mmsockets on the rear side of the amplifier.CONNECTING OUTPUTSLoad can be connected using banana plugs or spade lugs. A black binding post is considered “COM , while the three red binding posts are considered “hot ” , and the voltage is38V ( different from the model ) , 70V, and 100V.Note:Never connect the “ hot ” terminals together.When connecting load ( speakers ) , it is better to use one pair of output term in alson ly.If the PROT Led goes on steadily while power has bee n turned on and sig nal has bee nfed, there must be a trouble of output shorted. Please turn the unit off and correctthe trouble the n turn it on aga in.SPECIFICATIONSMODELPA3002PA4002PA5002Max.
