1. Power switch
To turn the unit ON or OFF, press the upper or lower part of this button. The LED above the switch will light to indicate
that the unit is ON.
CAUTION : Always turn on your power amplifier at latest, after all your other connected equipment, and always turn off
your power amplifier before your other connected equipment.
2. Peak LED/limiter L & R
3. Protection Led
The Protection Led illuminates RED when the amplifier is over-heated.or when a shorted load or DC is detected on
the amplifier output. The amplifier shall reset itself when the problem is solved.
4. Signal LED indicator L & R
These LEDs will light up green when the input detects audio signal.
5. Level controls
These control the level of signal coming into each channel. Turn these controls counterclockwise if the peak LEDs
illuminate steadily (indicating an overloaded input signal).
6. MIX switch
Push these switches if you want to link the input signal from one input to others.
7. Unbalanced RCA input
RCA-cinch input (mono)
8. LINK RCA output
RCA-cinch output for linking the input signal to another amplifier.
9.Output connectors (Binding Posts)
The speaker for each channel output can be connected to the screw terminal binding posts (banana jacks). (>4 ohm)
10.Fuse holder & power cord connector
This fuse holder contains an AC primary fuse. When this fuse blows, replace it with the same type fuse, size and
power rating (3,15AT). If it continuously blows, stop replacing the fuse and refer servicing to qualified personnel.
CAUTION:After checking the AC supply voltage, be sure that the correct fuse is in the fuse holder. The cord connector
is used to connect the AC power source to your power amplifier. CAUTION:DO NOT REMOVE THE CENTER
GROUNDING PIN.
NOTE
To bypass the build-in limiters, you have to remove the top cover of the unit.
inside you have to locate and remove jumper JP1 and Jp2.
Please contact a qualified technician to do this.
The red LED illuminates if the input signal of the amplifier to high. Occasional blinking of this LED
is acceptable, but if it remains (on) or more than intermittently, then you should lower the input level or reduce the
output
level of the preceeding component to avoid audible distortion.A built-in limiter will prevent excessive RMS clipping.
If you want to bypass the limiter function,then disconnect JP1 (left channel) and JP2 (right channel)inside.
Please contact a qualified technician.

MIX-BUTTONS
Cooling & Protection systems
This power amplifier is designed for dynamic high quality sound reproduction. Due to its low impedance driving
performance, and in combination with 16 ohm loudspeakers, it is the ideal solution for well-dispersed 'background-sound'
systems (many speakers at moderate sound level). This power amplifier is not designed for continuous high power
applications.
Keep the amplifier in a cool 'free-air' environment, especially the side heatsinks. When the amplifier is driven into too high
levels, then the 'overtemperature' protection may be activated. The 'protect' led will go from green into red. It will reset
automatically if the temperature is safe again.
If you don't lower the levels and just keep on driving into high levels, then the temperature protection of the transformer
may be activated. Then all LED's go out, and you have to wait 5-10 minutes before it will be rest automatically.
MIX button
The three MIX-buttons can be used to link the input audio signal
to the amplifier next of that input.

HUMM & BUZZ
• If ‘Hum’ or Buzz’ occurs when connecting different inputs, then this is often caused by
‘GROUND or EARTH LOOPS’.
Inside you can disconnect Jp3 to break this ground loop.
Please contact a qualified technician to do this.
