6. Troubleshooting
• The amplifier stops working.
Turn the volume knobs of both channels to zero, switch off the amplifier and disconnect from the
mains. Check the front panel, the fuse and all input and output connections. Replace the fuse with a
fuse of the same type and ratings.
• No sound when power LED is switched off.
The power supply is not connected or the amplifier has a blown fuse. Check the power connections
and switches, or replace the fuse located below the power input.
• No sound when power LED is switched on.
No or low input, or faulty speakers. Check if the input is connected and if the LED shows the
presence of a signal. Gently increase the volume level and check the speakers and speaker
connections.
• Hum or buzz.
Power supply noise is picked up in the signal path or earth problem. Only use good quality, shielded
signal cables and ensure they are kept away from the power cables and other AC-powered
equipment. Use a mains tester to ensure the mains outlet has a good earth.
• Distorted sound.
There is an excessive signal level or damaged signal cables. Check the LED to ensure the input level
to the amp is at the correct level. Only use good quality, shielded signal cables and protect them
from damage.
• Sound cuts out.
The signal cables are damaged or the connectors are not properly inserted. Check all cables and
connections.
• Protect LED on
• Check if the amplifier is not overheated. Clean ventilation openings when necessary.
• Check whether the connected speakers have the appropriate impedance. If not, connect speakers
with sufficient impedance. Also verify that the speakers are not short-circuited. Inspect the wiring.
• Inputs receive DC voltage or another technical fault condition has occurred. Switch off the amplifier
and contact your local dealer for servicing.
7. Maintenance
• Regularly wipe the amplifier with a moist, lint-free cloth. Do not use alcohol or solvents.
• Ensure that liquids are not spilled into the enclosure through the ventilation openings.
• Contact your HQPower™ dealer if your amplifier needs servicing.
