TROUBLESHOOTING

PROBLEM

CAUSE

SOLUTION

No sound from the unit. The power on
LED indicator (on the front of the unit)
does not light up when the power switch
is at the on (“|”) position.

1 - Bad or loose AC connection to the
unit or the mains outlet.
2 - Faulty AC cable.

3 - Blown Fuse.

1 - Check you connections. Insert the IEC
plug securely into the unit's AC socket.
2 - Check the cables, connectors and AC
power with a suitable mains tester.
3 - Replace fuse on fuse holder under AC
input with a same fuse type only. If it
blows again, take the unit to a service
centre.

No sound from the unit. The power on
LED indicator (on the front of the unit)
lights up when the power switch is at the
on (“|”) position.

1 - The channel (MIC or LINE) or the main
(LEVEL) volume controls are set too low.

2 - The signal source is sending no signal.

3 - Defective cable.

1 - Turn up the volume for the channel
you are using (MIC or LINE) as well as the
main LEVEL control.
2 - Check that the mixer or sound source
is sending signal to the unit.
3 - Check that the cable from the sound
source to the unit is connected correctly.
Replace the cable if defective.

Full power cannot be obtained. The
OVERLOAD or LIMIT indicators never
lights up.

1 - The channel (MIC or LINE) or the main
(LEVEL)

volume

controls

are

not

at

maximum.
2 - The signal source does not have a hot
enough output.

1 - Turn the channel (MIC or LINE) or the
main (LEVEL) volume controls up.

2 - If using a mixer, use the balanced
output if available. Use a professional
mixer with a hotter output, or use a
preamplifier between the sound source
and the unit.

Feedback appears when the LEVEL is
turned up.

1 - The microphone is pointing towards
the speakers.
2 - The microphone is not directional
enough or the talker/performer is too far
from the microphone.

3 - Incorrect EQ.

1 - Place the speakers in front of the
microphones.
2 - Use quality directional microphones
such as cardioid, super-cardioid or hyper-
cardioid

and/or

nicely

ask

the

talker/performer to talk.
3 - Avoid high gain settings on the
equaliser.

Sound

is

distorted,

but

LIMIT

or

OVERLOAD indicators do not light up.

1 – The mixer is distorting.

2 – The signal reaching the unit is too hot.

1 - Turn the down the main out or the
channel gains on the mixer. Check the
signal source.
2 - Set the LEVEL control no lower than
ten o'clock. Lower the main mixer output
level.

Sound is distorted and very loud. The
OVERLOAD (or LIMIT)

indicator lights

up.

LED

1 - The system is overloaded and has
reached maximum power.

1 - Turn the mixer level down.

2 - Turn the channel (MIC or LINE) or the
main (LEVEL) volume controls down.
3 - If the LIMIT LED lights up, press the
LOW CUT button.

The microphone can hardly be heard with
the LEVEL control at maximum.

1 - The unit is not being used in
microphone mode.

1 - Set the LEVEL control to 9 o'clock
approximately and press the MIC/LINE
button. Adjust the LEVEL control further
to get the desired level.
2 - Adjust the

control

MIC GAIN

further to

get the desired level.

When speaking into a microphone, voices
are heavy.

1 - Microphone proximity effects. Bass
gets dramatically louder when speaking
too close to the microphone.

1 - Speak a little further away from the
microphone. Press the LOW CUT button
and /or turn down the low frequency
equalisation if available.
