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
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.
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” (70V or 100V) output, while the each
loudspeaker should use a separate transformer and the total power of connecting
loudspeakers should be less than rated power of amplifier.
Loudspeaker which close to the amplifier also make use of “fixed resistance” (4
Ω) output, while the total resistance of connecting loudspeakers should accord with
4-16Ω.

Note:
When connecting loudspeakers, it is better to use one pair of output terminals only.
Never connect the “hot” terminals together.
