(6.3mm Socket)
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 shall 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.
Note:
Never connect two hot terminals (labeled 4Ω, 70V, 100V) together.
Only choose one pair of output terminals for speaker connection. The connection ways
shall be COM-4Ω / COM-70V / COM-100V.

Tone and volume:
MIC1, 2, 3, 4, 5 have separate volume control. MIC4 and AUX1 or MIC5 and AUX2 have a common
volume control knob.
MIC
: MIC inputs are balanced with phantom power. Two types of MIC inputs available: 6.3mm
(MIC1, 4, 5) and XLR (MIC2, 3). MIC4 & 5 inputs are compatible with AUX1 & 2 inputs.
“MIC4/AUX1” and “MIC5/AUX2” can be selected through the switches on the back panel. 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.
“BASS” and “TREBLE” knob provides the tone control of overall system.
Chime / Siren:
The LED indicator above the button will be lit up simultaneously. Pressing the “SIREN” button again
will stop siren broadcasting and the LED will be turned off.
Levels of priority muting:
has the highest level of priority muting and can override all other input signals. Siren has the second
level. Chime has the third level and can override all input signals except for MIC1 and siren.
REC input / output:
cassette player, etc.) The volume of this input is not adjustable. While recording program signal can
send to REC input and at the same time signal send out to recording equipment through REC
output. REC output also can be used for monitoring the other input signals.
Pressing the “CHIME” / “SIREN” button will activate the chime or siren circuitry.
MIC1, siren and chime have priority muting functions. MIC1
REC input can connect to an external source (CD player, tuner,
PRECAUTION OF INSTALLATIOM
1. Do not block ventilation holes.
2. Do not use this amplifier if the power cord is frayed or broken.
3. The amplifier should not be placed in any of the areas:
1) poor ventilation
2) exposed to sunlight directly
3) high ambient temperature or adjacent to heat-generating equipment;
4) high humidity or heavy dust;
5) Susceptible to vibration.
4. Make sure the plug conforms to the socket.
5. For safety, please make grounding.
6. Short-circuit fault happens when short alarm rings during operation, In such case, switch off the
power immediately and check the faults before switching on again.
