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.
