1. POWER switch
When pressed, the soft start circuit will run thus avoiding a power surge. After 3-4 seconds, there will be a clicking noise that indicates that the
soft start process has finished. After a further 1-2 seconds there will be another clicking noise to indicate that the amplifier is now working.
2. BRIDGE MODE LED
This LED will be lit when the amplifier is operating in Bridge Mode.
3. MONO MODE LED
This LED will be lit when the amplifier is operating in Mono Mode.
4. CHA/CHB input level control
Adjust to acheive the desired volume. Only use CHA control when running the amplifier in Bridge or Mono Mode.
5. CHA/CHB protection indicating LEDs
The LEDs will be lit in the following three conditions:
After turning on or turning off the amplifier the LEDs will light temporarily.
When the amplifier temperature is over 85ºC.
When there is a fault with the amplifier.
6. CHA/CHB peak level indicating LEDs
The LEDs will be lit in the following situations:
When the output signal has reached its clipping level, the LED lights; possibly resulting in distortion. Should this occur, adjust the input level
control so that the Peak LED turns off.
If the input signal is too loud and the Peak LED lights continuously, but no sound is heard from the amplfier, it is possible that there has been a
short circuit. You should turn off the amplifier. Find out where the trouble is and renew operation.
7. CHA/CHB signal indicating LEDs
This LED will be lit when the amplifier is working normally.
8. MAINS input
Connect the supplied mains cable to the IEC socket and integrated fuse holder.
9. FAN & ventillation apertures
During operation, the amplifier produces heat that must be dissipated. The fans inside the amplifier must be able to evacuate the heat in the
most effective way. Therefore is it very important not to cover any of the ventilation openings as this may result in overheating.
10. L+R SPEAKERON outputs
Use these connectors to connect your speakers (impedance >4ohm) in stereo or mono mode. Wiring of these connectors is as follows:
POS(+) = PIN1+ and PIN2+ / NEG(-) = PIN1- and PIN2-
11. BRIDGE SPEAKERON output
Use this connector to connect your speaker cabinet (impedance >8ohm) in Bridge Mode. Wiring of this connector is as follows:
POS(+) = PIN1+ and PIN2+ / NEG (-) = PIN1- and PIN2-
Speakeron wire connection
12. 30Hz LOW CUT FILTER
This eliminates unwanted subsonic frequencies under 30Hz. In most cases these frequencies consume a lot of energy without adding any
value to the music.
13. OPERATION MODE switch
Used to set the operation mode of the amplifier. The most common operation mode is Stereo. If you need more power, you can operate the
amplifier in Bridge mode. In mono mode you only have to connect the CHA input to both outputs.
14. INPUT SENSITIVITY switch
Choose one of three different input levels: 26 dB / 32 dB / 1.4V
15. BALANCED XLR outputs
Can be used to send the signal to another amplifier. Pin1: signal ground / Pin2: signal+ / Pin3: signal –
16. BALANCED XLR inputs:
Pin 1: signal ground / Pin 2: signal+ / Pin3: signal-
