Hi, I have a Jamo i300 sub.the left speaker contact doesn't work

SOURCE: JBL Creature doesn't work

make sure the triangles on the plugs are lined up when you push in the plugs!

SOURCE: Want to use only subwoofer of HK695

The problem is that you need the satallite speakers , they have the volume control on them which thats why you only hear the subwoofer.. yes , i tried other speakers to it and no sound either.So you will need the satellite speakers it come with.. good luck!!

SOURCE: No sound from the System, Power light is on the

make sure you plug the subwoofer into the green jack port on your pc.

The fault is on the amp! It sounds like the protection circuit is detecting a surge on the channel and shuts it down to protect the speaker. I would check the semiconductor device(s) for the right channel on the heatsink of the amp. You might even see damage of burning on one!

SOURCE: ADA745 speakers have no output

Had the same issue as treefarmer and guest. Initially I thought that the voltage controlled pre-amps were the problem as well but further testing proved that wrong. If you remove the yellow wire from the RT Front speaker PCB and measure the voltage at the wiper of the pot it is still too low (should swing from 0 to 5 volts). On investigation it turned out that the pot was failing.

I couldn't find a proper replacement pot so had to fix the broken one. After removal and dissassembly it discovered there was a leakage path between the carbon trace and the bushing assembly. The top deck which contains the carbon path for the wiper can be removed by bending back the tabs that hold it to the metal case. Carefully cleared the shorting path with a probe and retested with an ohm meter..

Re-installed and wala it works!
