RISK OF ELECTRIC SHOCK
DO NOT OPEN
CAUTION
CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK.
DO NOT REMOVE COVER (OR BACK).
NO USER-SERVICEABLE PARTS INSIDE.
REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
WARNING
To prevent fire or shock hazard, do not
expose the unit to rain or moisture.
This symbol is intended to alert the user to the
presence of uninsulated “dangerous voltage”
within the product’s enclosure that may be of
sufficient magnitude to constitute a risk of electric
shock to persons.
This symbol is intended to alert the user to the
presence of important operation and main-
tenancy (servicing) instructions in the literature
accompanying the appliance.
Caution: To prevent electric shock do not use this (polarized) plug
with an extension cord, receptacle or other outlet unless
the blades can be fully inserted to prevent blade ex-
posture.
Attentions: Pour prévenir les chocs électriques ne pas utilizer cette
fiche polarisée avec un prolongateur, une prise de
courant on une autre sortie de courant, sauf si les
lames peuvent étre insérées à fond sans en laisser
aucune partie à découvert.
Although it is neither complicated to install nor difficult to operate your PA amplifier, a few minutes
of your time is required to read this manual for a properly wired installation and becoming familiar
with its many features and how to use them. Please take a great care in unpacking your amplifier
and do not discard the carton and other packing materials. They may be needed when moving
your set and are required if it ever becomes necessary to return your set for service.
Never place the unit near radiators, in front of heating vents, in excessively humid or dusty
location to avoid early damage and for your years of quality use. Connect your complementary
components as illustrated in the following page.

FEATURES
• THERMAL PROTECTION & AUTOMATIC IDLING CIRCUITRY
To insure stability and reliability against over-current and over-heating, thermal protection
circuitry is provided. In addition, automatic idling circuit is provided to protect against thermal
run-away.
• BALANCED INPUT
A balanced input is provided to reduce hum picked up from a long distance input cable and to
avoid ground loop problem when you build the system.
• GAIN ADJUSTMENT
You can adjust the input gain from –12dB to 0dB (1V) by using of input gain adjust control.
• USE OF EMERGENCY BATTERY
You can operate this PA amplifier by using emergency battery for unexpected AC power failure.
• COMPACT SIZE
For valuable saving in rack space and slim exterior view, this amplifier is designed with a
compact size of 3µ.

1. POWER INDICATING LED
This LED indicates power is turned ON.
2. POWER SWITCH
Pressing this switch to ON will make the power indicating LED ON and supply the power to
unit.
3. OUTPUT LEVEL INDICATORS
These LEDs indicates the output level of this amplifier. Be sure not to operate the unit with the
clip LED ON continuously (RED).
4. PROTECTION INDICATOR
This LED indicates the condition of the protection circuit. When the protection LED is “ON” the
amplifier is not operating normally (power on delay, overheating and limiting), please check
the INPUT/OUTPUT condition of the amplifier.
5. FAN
The fans should be kept free of all obstructions and be accessible to cool fresh air when
possible. It is important that the fans be used in a dust free environment.

REAR PANEL CONTROLS
1. SPEAKER OUTPUT TERMINALS
These terminals are for connection of speaker lines to deliver power output to speakers.
Impedance (voltages) of 4Ω, 8Ω, 70V and 100V are provided for convenience. In any case,
use the speakers whose combined impedance is equal to or higher than the rated output
impedance of amplifier.
2. INPUT JACKS
These input jacks and terminals are for the balanced input signal. You can connect amplifiers
in parallel by using XLR jack.
3. LEVEL ADJUST CONTROL
This control is for adjusting the level of amplifier from –12dB to 0dB with the reference input
sensitivity of 0dB (1V). Rotating the control clockwise increases the level and counter-
clockwise decreases the level.
4. FUSE HOLDERS
These fuse holders contain AC. Replace them with the same type fuse when they are blown
out. If they continuously blow, stop replacing fuses and refer servicing to qualified personnel.

5. AC INLET
This terminal is connected AC input cord.
6. HIGH-PASS FILTER SWITCH
This switch is for activating the High-pass Filter circuit, to protect speakers from excessive low
frequency power demands. The –3dB frequency of the High-pass Filter is 400Hz.
7. EARTH LINK SWITCH
This slide switch provides for separation of “safety” earth and “signal” earth to prevent from
hum loops.
8. DC INPUT TERMINALS
These terminals are for connecting DC power supply of battery, Connect red colored terminal
to positive lead of battery and black colored one to negative lead of battery.
9. VENTILATOR
This ventilator releases an heated air occurred inside the set.
Be careful so that this ventilator is not closed by any obstruction.
