OPERATING PRECAUTIONS

1. 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.

2. 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.

3. If the PROT Led goes on steadily 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.

CONNECTING INPUTS

either the 3-pin XLR-type connectors

(Figure 1 ) or 6.35mm sockets on the

rear side of the amplifier.

CONNECTING OUTPUTS

Output terminals are on the rear panel. 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".

Usually make use of "fixed voltage" (
