Troubleshooting
Most difficulties in audio systems are the result of incorrect connections, or improper control
settings. If you encounter problems, isolate the area of the difficulty, check the control settings,
determine the cause of the fault and make the necessary changes. If you are unable to get sound
from your amplifier or its behavior is not as expected, refer to the suggestions for the following
conditions:
No response to the mains switch: Verify the mains connection. Unplug the power cable from the
Kaluga and try to power another device with it. If this works, please contact us. The unit may need
repair.
The unit responds (as witnessed by lights and clicking relays) but no sound: Verify correct speaker
wiring.
Quiet, distorted sound with interruptions: You probably have a short across the speaker or amplifier
terminals, for instance two uninsulated spade terminals touching. Reinstall your speaker cable.
The indicator LED blinks slowly and never goes to permanently on: Switch off the amplifier with the
mains power switch. Wait 10 minutes. Switch on the amplifier with the mains power switch. If the
problem still appears, please contact us. The unit may need repair.
