The amplifier goes in mute mode due to output short circuit, overloading or poor
ventilation resulting into the rise in temperature either of the output devices or the power
transformer. Switch off the amplifier to cool down. Check if the fan is working,
proper ventilation is provided & output connections are as recommended.
To restore normal operation, turn down the volume control, power on the amplifier
once and increase the volume control for desired output.
6. Distorted Sound
1. The input signal level may be too high. Turn down the amplifier level controls.
2. Check if the level of the input source. If it is high, reduce the input signal level.
The amplifier should never be operated at a level which causes the Clip LEDs to
illuminate constantly.
5. No Sound
Move cabling and signal sources to identify the problems areas in the system. Cables with faulty shielding are a
frequent entry point from hum. It occurs due to ground loops.
If the humming persists, kindly get in touch with our authorised service personnel.

8. Hum.
Unplug the amplifier input to confirm whether the hiss is from the source or a device upstream. The erratic or
popping noises indicate an electronic fault in the offending unit.
9. Hiss.

4. No Sound
1. The amplifier goes in mute mode due to excessive input signal, speaker impedance
mismatch or output short circuit.
2. Check the speaker impedance & speaker wiring for stray strands or breaks in the
insulation.
3. Reduce the volume control, for desired output.
