STEREO is the normal mode of operation where each input is delivered to each output independently
BRIDGE mode couples both amplifier sections together to deliver the full rated power to a single output. The
minimum impedance is 8Ω in this mode. An LED (“BM”) shows when this mode is engaged
The GROUND LIFT switch disconnects signal ground (or “earth”) from mains ground. In certain cases, it may help to
alleviate mains hum otherwise, leave ground connected to mains ground.
With CH1 and CH2 level controls turned fully down, switch on the power to the amplifier. This product has a “soft-start”
function which makes some checks before engaging power to the amplifiers, which may take a few seconds.
With mixer (or other signal source) levels turned down, gradually increase the amplifier’s CH1 and CH2 level controls to
the required level (normally full) and then gradually increase the signal level from the mixer until sound can be heard
through the speakers and then up to the required level.
During use, the LED indicators will show if a signal is present, if half output is being produced and if the output is
reaching clip level. If the red CLIP LEDs illuminate more than very briefly, reduce the volume until they hardly light at all.
If the internal protection circuitry detects a fault in the speakers or amp, the amplifier will enter Protect Mode and the
OUTPUT LED(s) will illuminate on the front panel to show this. Switch the amplifier off and check the entire system
(including leads) before powering up again. If still in Protect Mode, seek advice from qualified service personnel.
Before powering down, turn CH1 and CH2 level controls fully down to avoid loud noises when switching off.

Troubleshooting
No power light on front panel switch
Ensure IEC is connected to mains and mains is on and lead is in good condition
Power light is on but no other LEDs and not
output
Check input signal and connection leads
Ensure CH1 and CH2 level controls are not turned fully down
Power light and Signal LEDs are lit but no
output
Check speaker cabinets are not blown and are in good working order
Check speaker leads are in good condition and connected properly
OUTPUT LED is continuously lit and there is no
output
Switch off and disconnect from mains
Check speakers are in good working order and not shorted (using a multi-tester)
If still in Protect Mode, switch off again and refer to qualified service personnel
Output is very distorted and “CLIP” LEDs are
lighting
Check speaker impedance is not below rated Ohms
Turn down Input level from audio source
Switch GAIN at rear to a lower level
Turn down CH1 and CH2 level controls
Output is working but at very low level
Ensure input source is at line level
Increase input level from audio source
Turn up CH1 and CH2 level controls
Switch GAIN at rear to a higher level
