SOURCE: volume level dropping unexpectadly

The A1 has an internal self diagnostic program which you can go through to find the fault. You can access the diagnostic program by simultaneously pushing some buttons on the front panel. The Yamaha service manual for the A1 tells how to do it and what the diagnostic codes mean. You can get a copy of the service manual on the web from several suppliers for a small fee.

OK. I dont know the answer to your prob, but to let you konw that youre not in this alone, my amp used to occasionly lose considerable volume in one channel. this could be remedied by cracking the volume up to max for a half second or so. (Not a great solution!!) It has finally given up the ghost ...I have lost one channel and the doctor says it wont come back. Not only this but they claim that spares ceased to be sold back in the 90's. having said this I have enjoyed this amp for almost 20 years. I think its time to put it to pasture.

Audio sounds very muffled, all channels.. Sounds like a speaker issue. Tried every thing.

Also check the DSP settings and the Equalizer levels

Cambridge azur 650R shows "PROTECT" after Volume more than 1/4, protection-relay works, loudspeakers&cable are o.k, WHY?/Solution (relay broken)?

What ohm rating does the receiver have and what ohm speakers are you connecting. If the receiver is rated for 8 ohm speakers and you are connecting 4 ohm speakers, you are overdriving the amplifier. This will cause the protection to trip. Also make sure your speakers polarity are matched. If they are out of phase this may also cause a problem.

Sony STR-DH510 Multi-channel AV receiver connected to cambridge soundworks ensemble IV w/ passive subwoofer: no sound from center channel during viewing, or during speaker level test- all other speakers...

The STR directs sound to the center as instructed by its speaker setup. You say the center does not work on calibration. Is it defined?

Prove another speaker does or does not work on the center output. Then we'll know if it's the receiver or the speaker ensemble that has the problem.

Have you checked the manual for this "
There is no sound, or only a very low-level sound is heard from the center/ surround. "?

The receiver works ok until the vol is reduced and the right front channel drops out. Increasing the vol usually picks up the dead speaker but it drops out again when the vol is reduced. I've tried...

Make sure the audio level on the left and right channels are balanced. Check the menu for audio levels to adjust and make sure they are not maladjusted. If all levels are adjusted properly then the volume control or volume control circuity may be at fault.

Low volume through amplifier

Turntables generate a very low signal. Phono inputs on receivers containa pre-amp section to boost the signal to "line level" or the same level as other audio devices. I would suspect that you need to add that pre-amp section. Phono preamps are available for around $20 or so and are inserted between the turntable and the standard audio input on the receiver or amp.

Hope this helps,
Dan
