OPERATION:
Make certain that speakers and input sources are properly connected before switching on.
Keep volume level turned down to minimum before switching on.
Protection LED Indicator lights on while operation when faults happen. Switch off the apparatus
immediately and correct the faults before switching on.
INPUT CONNECTION:
The Input sockets/terminals are on the rear
panel under the label “IN”. There are three inpu
ways: 100v input terminal, two XLR input
sockets (figure 1), and two 6.3mm RCA input
sockets.
Positive
Negative Input
OUTPUT CONNECTION: Figure 1 3-pin XLR Input Sockets
Speaker output terminals are on the rear panel. The terminal under the label “COM” is
COMMON. The terminals under the labels “4Ω, 70V, 100V” are Hot. The connection ways
should be COM-4Ω / COM-70V / COM-100V.
Normally the “rated power” (70V / 100V) output terminal is used in output connection. The
connected speaker should be with a transformer, and the gross power of speakers should be
less than the rated power of the amplifier.
“Rated Impedance”(4～16Ω) output terminal can be used when speakers are fixed closely, and
the gross impedance of speakers should be 4～16Ω.

XLR terminal or 6.3mm RCA terminal under the label “OUT” is line output terminal.
NOTE：
Only choose one pair of terminals for speakerconnection.
Never connect two Hot terminals (labeled 4Ω, 70V, 100V)together.
