Make sure the AC main voltage is correct and is the same as that printed on the rear of the amplifier. It is always to prevent speaker damage if there is a high signal level at the inputs.

CONNECTING INPUTS

Input connections are made via either the 3-pin XLR -type connectors (Figure 1) or 6.3 mm sockets on the rear side of the amplifier.

CONNECTING OUTPUTS

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”, 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.
