OPERATING PRECAUTIONS
Make sure the AC mains voltage is correct and is the same as that printed on the rear of the amplifier.
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.
INPUT CONNECTING
Input connections are made via either the 3-pin XLR-type
connectors (Figure 1) or 6.35mm sockets on the rear side
of the amplifier.
OUTPUT CONNECTING
Load 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”.
If the PROT Led goes on steadily and the buzzer sounds while power has been turned on and signal has been fed,
there must a trouble of output shorted. please turn it off and correct the trouble then turn it on again.
