One of my channel output went out. How can I fix this?

send a signal thru the sub 4 insert and see if it comes out the sub 4 output. You may have jarred a ribbon cable loose in transport.

The problem is more likely to be with the wireless headphone set rather than the TV. It makes no sense that the signal changes channels. The only difference betweent he fixed and variable output is whether or not the volume changes the output signal amplitude. The channel selection process is not handled there. The distortion is likely due to the input of the wireless being overdriven. If available, turn down the input gain on the wireless and try again. Please update this with the results.

Thanks,
Dan

Blown High output resistors. Definately repairable. Good luck. If you can solder, try removing the high output resistors, replace them with parts from Fry's. Cheap fix. Good luck. Depending on the size of the amp, there will be about 6-10 of them. Check all channels on the amp.

This particular mixer offers a usb (2 channel connection) that can be simply plugged into the computer usb 2.0. These channels should be available in Sonar from the channel Input/output drop boxes. You may need to restart Sonar, the mixer or both for them to be recognized. You may also need to run the Wav Profiler in Sonar. Typically the Wave Profiler is found in the Options>Audio menu but may be different on each edition of Sonar. The above info is for Sonar 7.

If you are wanting to record several channels at once then I would recommend connecting your Mixer's Direct Outputs from each channel to a corresponding input of the soundblaster if your soundblaster supports multiple channels. And then use the usb outbut from the Sonar to monitor the computer playback of your master stereo channel. Or, you may connect the soundblaster outputs to unused channels of the mixer or to the tape return or auxilary inputs to monitor the computer playback on the mixer.

Alternately you can send the signal to your soundblaster via the buss outputs. This will limit the number of simaltanious output channels to the number of busses on the mixer, but you can send any mixer channel to any buss without unplugging the instruments or mics.

Here's the link to the page where you can download the free pdf manual for this mixer. Page 14 explains the output connections and has diagrams.

If you are convinced the left channel is out, and have tried using the speaker B outputs with your front spkrs. to see if the left channel works or not.....i would suggest getting a new receiver. You would have a new receiver with a some sort of warranty, and an option to buy extended protection. Unless there is a sentimental value for you..then keep it and get an estimate. Hope this is helpful.

you ruined the audio output transistor(s) for that channel,can you still hear the other channel or is this also quiet,if so,then you will need to replace at least the channels transistors you said you shorted and then check opposite bank for transistor output leakage,if these outputs are (STR) output paks instead of the older oval paks,just replace the whole STR pak and this may be both channels on one SRT-pak on one chip

Hiya, dont have a diag either what you will have to try and is compare the left channel with the right. There will be 2 driver transistors (also likely on heatsink) close to the outputs. Check which driver drives which output on the left, then match it on the right. Those same drivers could very well also be a problem on the right as they often go with the outputs. There is a possibilty they have smoked again. See here to test FETS

Basically the left will match the right but not similar locations but definitely by track joins.

Also check the power resistors at the output. Often also go.

Hope that helps

THE MONITOR OUTPUT AMP MAY HAVE BLOWN...COULD MAY ONLY BE THAT THE JACK IS BAD OR JUST A COLD SOLDER JOINT.....OR IT COULD BE JUST ABOUT ANYTHING IN THE MONITOR CHANNEL PUSH BUTTON MASTER VOL FOR THAT CHANNEL TAKE IT APART TAKE A LOOK AROUND BEFORE YOU BRING IT TO A REPAIR SHOP IT CANT HURT GOOD LUCK

Assuming that you've confirmed that the speaker is in good working order and that the wiring isn't shorted in any way...

There are separate power supplies for the high and low amplifiers. It's possible that the one for the sub output has failed. If that's the case, the output transistors probably failed and that's what damaged the supply.

Generally, I'm willing to help people repair their amps but this is a large, complex amplifier and it should be repaired by a qualified technician.

Set the HDMI to "Stereo" from multi-channel.
