Question about Amplifiers & Preamps

1 Answer

Preamp noise My Audio Buddy Preamp is hissing and crackling. One input is not working at all. The recording channel levels on my software are going sky high even without anything plugged into the preamp. Through a process of elimination I have worked out the cables etc are OK. Please advise if it is repairable and if so, an estimate of cost would be great. Thanks

    Thanks!

    I thought that a repair might not be worth it. Thank you for confirming. I will try and track down an alternative preamp on ebay as a new Audio is still expensive at the moment. Thanks also for the link to zzsounds!

Hi KenO2

First thing to check is that the phantom power is not turned on. If you are using a condenser mic, then it should. If you are using dynamic mic, then it will crackle and makes weird noises in the manner you describe. Other than that it sounds like you have a failing op amp in your preamp. This sort of repair work is not expensive(with respect to the outcome). I would anticipate $40-60 to fix it. Trouble is you can replace it super cheap at the moment 45% off for $64.95plus $9.95 shipping from zzsounds

So I guess that it may not be worth repairing, and more a replacement item for that money. If you have a mate with electronics experience, you could just replace the opamps at home for $10 worth of parts.

If you think my advice helped you to work out what to do, a FixYa rating would be great. Cheers

    Hi Ken, I know that what I had given you was "helpful", was expecting that I had given you enough information for you to make a decision about what to do with your problem. If you still have any questions I am happy to go the extra mile for you.
    A "FixYa" rating is the only thing that really counts for us in here as I don't get paid for taking the time to work through this problem for you. Any chance of an upgrade. Thanks mate :)

Preamp Noise


The rectifier is the only thing wrong with the amp. Typically a bad rectifier will pop fuses but that is not the only thing than can cause that. You could try pulling tubes to see if you could isolate the problem. Just be careful if you haven't even taken the tubes out before, those PCB sockets are kind of flimsy. pull one tube at a time and see in the crackling goes away

My behringer europower EP2500 poweramp has a bad hiss on channel 2 What could this be?


There is a possible noise build up on your CH2 due to failure or weakness of the LCR network of the preamp circuit. It could also be a noise within any semiconducctor or the preamp IC. Unless you can do a signal test with the elimination of the input to the output amplifier, the fault will not be say to isolate. Hence if youarre familiar do the test by approching from the output amplifier's input, proceeding to the main input where the faulty section can be identified. Hope this helps. Good day

Yamaha m70 amp and c70 pre-amp right speaker stopped working


First, lets's determine if it's the amp or the preamp...

Swap the Left and Right channel cables between preamp and the amp with each other.

Did it stay on the right? = amp problem.

Now on the left? Preamp or source.

Plug any Line Level device (CD?) directly into the amp inputs. Work now? Preamp problem.

ALL sources? Preamp - toggle all controls, especially a Tape Monitor to possibly wipe of any built-up oxides in them.

Bass to PC recording problem


Hiya, it sounds a little like either the pick up in the guit is losing it (try another amp/combo etc) or more likely i think the sound card might be the problem on the input and filtering the low end of the bass after a while. Strange but seems most likely. Try a friends PC as well. A pre amp wouldnt help as if the card is losing...well you get the idea. Might have to get a different sound card.
Best i got...good luck

Preamp not working


befor we go inside we make cleaning with lubricant contact cleaner from radio shack and apply it over all control switches while you are moving it-apply also in all sockets and put your plugs in it(in-out-in-out).after all above if not pass you have to ask for help from qualified service center.

I receive a radio channel in one of the outputs of the preamp


I would use sheilded wire on the mic with the least amount of cable. You can relocate the pre amp with aluminum foil wrapped around the pre amp. also turn the gain on the mic down as to eliminate any interference from your strong radio station nearby. Randy
