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 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 have a matching transformer, and the gross power of speakers should be less than the
rated power of the amplifier.
“Rated Impedance”(4Ω) output terminal can be used when speakers are fixed closely, and the gross
impedance of speakers should be 4Ω.

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

OPERATION INSTRUCTION
Tone and volume:
“MASTER VOL”, “BASS”, and “TREBLE” knobs provide volume and tone
、
control of overall system. MIC1, 2, 3, 4, 5 6 have separate volume control. MIC5 and AUX1 or MIC6
“CHIME VOL”on the rear panel can be adjusted to
control the volume of chime.（volume up by turning it clockwise, down by anti clockwise）.
and AUX2 have a common volume control knob.
MIC: MIC inputs are balanced with phantom power. Two types of MIC inputs available: 6.3mm
、、 、
、、、
(MIC1,2 3 4, 5 6) and XLR (MIC 1 2 3 4). MIC1-4 are compatible with two input jacks: XLR and
6.3mm. MIC 5 & 6inputs are compatible with AUX 1 & 2 inputs. “MIC5/AUX1” and “MIC6/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 feedback (howling), keep volume level down to minimum before connecting
microphone.
Microphone application: The microphone is provided with the phantom power supply, and when
the capacitor type microphone is used, please set the phantom mains switch on the back panel to
“ON”.

Chime / Siren: Pressing the “CHIME” / “SIREN” button will activate the chime or siren circuitry.
The LED indicator above the button will be light up simultaneously. Pressing the “SIREN” button again
will stop siren broadcasting and the LED will be turned off.
Levels of priority muting: MIC1, siren and chime have priority muting functions. MIC1 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: REC input can connect to an external source (CD player, tuner, 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.
PRECAUTION OF INSTALLATION
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 connected to the socket.
5. For safety, please use electrical grounding.
6. Short-circuit fault happens when short circuit alarm rings during operation, In such case, switch off
the power immediately and check for short circuit before switching on again.
CAUTION
For safety, when “Power switch” is off, please detach the power plug from the power outlet.
The apparatus shall not be exposed to dripping or splashing and objects filled with liquids,
such as vases, shall not be placed on the apparatus.
To reduce the risk of electric shock, do not remove the cover.
No user serviceable parts inside. Refer servicing to qualified service personnel.
