    My Yamaha MX/CX-800 combo does the same thing. My left channel quits working and then the buzz begins when I reach back to tickle the RCA connection between the amp and pre-amp to get the left channel operating again. I'd rather not spend a bunch of money at a repair shop on 20+ year old equipment. Is there a way to repair this on my own?

Can i plug my phone into my p7000s yamaha amp I've bought. It has not been delivered yet. Also what is the option for speaker choice as I don't have a lot money spare. thanks.


This is a brilliant and hugely powerful amp. If you wanted you can take a 'y' cable out of your phone, mini jack into left and right 1/4inch jacks, to plug in directly. However, it would be better to invest in a small mixer, 5 channel maybe, around 40-60 pounds, with one mic channel and 2x stereo channels. This would allow you to keep the amp on full volume, for best results and control, while having a proper control unit with knobs or faders on a table top with the sound source. Far, far better than plugging in direct. Otherwise you would have to keep adjusting the controls on the amp, separate channels, which is a pain!
Take care over choosing speakers because if they are not powerful enough you will blow them up in your excitement! I'd go for a pair of 8ohm 400-600 watts rms. full range cabs - 12inch or 15inch driver with horns.

B&K AVP2000 left channel not working


Yes amps buzz when something gets near them - say a pen or probe and if you know what it is safe to touch a finger! Fortunatly for you the left channel is the same as the right. So if you believe it's the pre-amp work backwards from the where the power amp connects to the pre-amp, going through the pre-amp stage by stage - prodding the parts. Remember a buzz in the right a buzz in the left! No buzz in the left but one in the right fault found!
Ignore the power supply it's nothing to do with that as it's common to both channels.

Hi We have an Allen & Heath Mixing Desk connected to two Yamaha P4500 audio amplifiers (via graphic EQ and compressor/limiter) which power the 4 main and 4 side speakers in our church. We now want to...


'Splitting' leads is never the best way to distribute a signal. The best solution is to use the parallel inputs of the Yamahas to chain them together: mixer to amp1, amp1 to amp2, amp 2 to the Cloud. You should only need to use one input on the Cloud to drive all the channels, using the input switches at the rear.

Let me know if you need any clarification on this.

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.

Cambridge Audio Azur 340A amplifier,no sound


Start with the basics first. 1. With the amp on, in each imput socket plug a dual end phono cable in and touch the right and left plugs with your finger. You should get a buzz on each speaker. No buzz and the channel at that terminal is not working. If none of the terminals buzz. Then the amp is dead.
If some buzz and others not you have a pre-amp problem.
2: Amp Dead. Could be A power supply. B main pre-amp. C Power Amp.
The power supply check for a fuse.
The main pre-amp will only effect both channels if an IC controls both.
The Power Amp will again only loose both channels generally if it is an IC. It will be attached to a big heat sink and have lots of pins comming from it.
If it uses transistors for the main amp, you can check these with an Ohm meter. With the power off place the leads on each terminal of each transistor. If the meter goes fully over (like when you touch the leads together) each way it has shorted.
The thing to remember when repairing stereo amps. Is that the amp is two identical amps joined together. So what happens one side will happen on the other. If both channels don't work look for something that is common to both.
Good luck
PS never heard of 'cliperd'.

Distortion in a Yamaha CA-800


The only thing I can suggest is you look at parts that are common to both channels in the main amp part. Perhaps an IC?

Yamaha rx-797 w/Yamaha ge-60 eq utilizing prein/main out ..and ad


It sounds like you want to use the external amp rather than the internal one. If that is the case, just connect the output of the EQ to the input of the external amp. All you are doing is inserting the EQ between the amp stages now. Using the mx-1 rather than the internal amp is no different.

CS-800 buzz in channel a


First a couple of questions:

1) Is the level of buzz controlled by the volume control? Based upon your initial post I would think yes.

2)When you say you want to use the other amp as a regular amp, do you mean to drive a single speaker or more?

Might be caused by any of the Large Capacitors in the power supply section of the amp.
