Re: no sound from amplifier

1-check for blown fuse2-check for good cables to your loudspeakers
(no short circuit between cabels wire.)
about(nuorigin problem)-move the good speaker cables to the bad side and check if there is no sound the problem in your amplifier output stage and needs to be fix at workshop.

Russound CA6.4 amp / controller - 3 of the 6 zones can't switch source inputs.

I suspect the inputs will all go into an IC. You just need to trace one of them back till you come across it. Either the circuit around it will be the problem, or more likely the IC itself.

Sony s master digital amplifier

are you sure you have connected a sound source to the inputs correctly and turned on the sound source so it is playing into the sony?
If you have use the sony controls to turn up the volume and then select each input source one by one, do you then hear it?

NAD C320. Only one channel sounds. Problem with the volume control?

Did you try to switch the loudspeakers? Before changing anything always lover the volume and switch off the amplifier.
Assuming you tested already different inputs, you can be sure no cable from signal source is out or defect. (or did you nit check that first?).
When the amp is switched off, disconnect the speakers and switch left to right and right to the left output.. If the other speaker is quiet now, you are sure it is in the amp. Still his can be anything.
You can check the connections between the pre and main amplifier on the back side. When you have an extra set of interlink cables, perhaps you can cross the in and output there too. Take care every time you change something, lower the voltage and switch off the amplifier. Sudden clicks when switching on or changing anything can damage the amp and or the speakers.

Perhaps when you checked this you can locate where the problem is? Speaker, speaker cable, power amp, pre amp, (only a part of the pre amp.

Only two of my amplifier inputs are outputting sound correctly!

Odd one! Normaly you would loose a channel if the main amp was down, or the pre-amp was. But clearly the main is working. The only conclusion is that there must be more than one pre-amp and that's why the Tape section works. The only way to solve this one is to go inside and trace the imputs to where they join the PC board.
A helpful hint is that if you touch the audio section with a srewdriver, it will buzz! And since you have two channels which copy one another you can work out where the fault is. Because if it buzz's in the good channel, it should in the same place on the bad one.
WARNING don't stick your srewdriver on power parts, and don't short any part out with it.

Amp 100 Line 1 in problem

Hi JamesOBrien

That is a strange problem you have indeed. The amp switches automatically from one input to the other, with default to input 1. You say the source sound dips low, is this a source from another integrated amp, where the AMP100 is working as a zone 2 device? . Are you using it as a zone 2 amp, and plugging other devices in the zone 2 area? and lastly, are you using auto on functions? Let me know, and we may be able to figure it out for you.

If it is new, then it may be worthwhile swapping it over for another by the supplier of the amp

check volume balance between right and left-then change inter connection between sound source and amplifier with new cabel(i prefer gold plated type connectors)(see radio shack).
after that if the problem excit your fault in output transistors or output stereo ic depend on circuit design.

1-check sound input source(dvd -tuner-deck)and confirm that amplifier is assigned to sound source-you must check source with it is cabels.
2-check sound output with it is cabels(speakers).
3-if every thing is fine your amp has a problem and needs to go to service center.
