Speaker output terminals are on the rear panel. The terminal under the label “COM” is COMMON. The
terminals under the labels “4
Ω
, 70V, 100V” are Hot. The connection ways shall be COM-4
Ω
/ 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”(4-16
Ω
) output terminal can be used when speakers are fixed closely, and the gross
impedance of speakers should be 4-16
Ω
.
Note:
Never connect two hot terminals (labeled 4
Ω
, 70V, 100V) together.
Only choose one pair of output terminals for speaker connection. The connection ways shall
be COM-4
Ω
/ COM-70V / COM-100V.
Tone and volume:
“BASS” and “TREBLE” knob provides the tone control of overall system.
MIC1, 2, 3, 4, 5 have separate volume control. MIC4 and AUX1 or MIC5 and AUX2 have a common
volume control knob.
MIC
:
MIC1 has the highest level of priority muting function and can override all input signals.
Note: To prevent howling, keep volume level down to minimum before connecting microphone.

overrides other input signals.
The level of

can be adjusted within
the range from

by
adjusting
