Damage caused by connecting the amplifier to improper AC voltage is not covered by the three-year US warranty. Make sure the power switch is off before making any input or output connections.It is always a good idea to have the gain controls turned down during power-up to prevent speaker damage if there is a high signal level at the inputs.Figure 1 3-pin XLR-type connectorsCONNECTING INPUTSInput connections are made via either the 3-pin XLR-type connectors (Figure 1) or mm sockets 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 is 38V（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 terminals only.If the PROT Led goes on steadily while power has been turned on and signal has been fed, there must be a trouble of output shorted. Please turn the unit off and correct the trouble then turn it on again.SPECIFICATIONSModelPA3002PA4002PA5002Max.
