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 (Figure1/2 ) 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 P1 output, while the total resistance of conn ec ting
loudspeakers should accord with 4Ω.
Note:
When connecting loudspeakers, it is better to use one pair of output terminals only.
Never connect the “hot” terminals together.
