OPERATING PRECAUTIONS

Make sure the AC supply voltage is correct, it means the AC supply voltage must be as the

same as that printed on the rear panel of the amplifier. Damage caused by connecting the

amplifier to improper AC supply voltage is not covered by the three-year warranty.

Make sure the power switch is off before making any input or output connections.

To prevent speaker damage, it is always a good idea to turn the attenuator to minimum

before turn-on the amplifier if there is a high level signal at its input terminal.

The protection light on while operation means faults (e.g. overload or short-circuit)

happening. The power should be cut off immediately and should not be turn on before

correcting the faults.

Before turn on the device, using OUTPUT VOLTAGE SWITCH to set up the output voltage

value which matches the rated voltage of connecting speakers. The switch cannot be moved

during the operation.

Input Connections

Audio input connections are made via either the 3-pin

XLR-type connectors (Figure 1) or 6.3 mm sockets on

the rear panel.

EMC IN terminal only can receive the short-circuit signal which is compatible with DSPPA series

products.

Main Communication Interface can link with MAG peripheral control interface.

Communication Interface linking with Main Communication Interface of another amplifier to

make multiple device linkage.

Output Connections

Output terminals are on the rear panel. Speakers can be connected using banana plugs or

spade lugs. Speakers without volume controller should be connected with COM and HOT

terminals directly using broadcast line. Speakers with volume controller should be connected

with this amplifier's COM terminal and volume controller's SP terminal. Volume controller's

SP terminal R terminal and HOT terminal should be connected with the same terminals on

this amplifier. (Please refer to Rear Panel and Connections diagram)
