MOST amps have a small plastic plug in the center of the amps speaker output sockets use a small screw to pull these out.

Protection light comes on and volume returns to zero. I am using a Azur 540A. This issue occurs when I ride the volume above a certain point, which is NOT any higher than i've been running it for years....

Protection circuits respond to overloads. Unless the protection circuit is faulty there is probably something wrong with the power amp parts located on the heat sink.
It would be a good idea to have the top cover off (on power) and listen for that noise to try and pin it down what is making it.

Volume goes to zero and protection light comes on, any idea what the problem is?

Check the speaker wires for a short. Try operating the amp without the speaker wires hooked up.

Just set up my brand new cambridge audio azur 650a amplifier. It keeps cutting out with the protection light blinking three times indicating "overvoltage" according to the manual. I'm using it at...

Just make certain that the connections are all good with no wires touching. If it still doesn't perform after that return it to where you bought it and get a new replacement or your money back.

I have a red protection light flashing whenever i try to work my amp and i was just wondering what the solution is or how to reset it, thanks

Normally this means that the power supply or the load is incorrect.
Have you very low impedance speakers ?
Have you tried disconnecting speakers from amp and powering it on.
If it does and you do not get any protection light you need to investigate your speakers.

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,

My amp states overload protection and no sound from both front speakers but all other speakers are working

Unplug speakers. Try headphones - are they working? Are speakers correct impedance? If it says 8-OHMs output, are you using 2-OHM or 4-OHM speakers, if so, not good. Sound like wrong impedance speakers or a short in the speaker wiring/connector.

Put teh wire of the cable in the side of the plugs once you have untwisted them - they dont come out.

Souud delay on tv /amp

Instead of connecting each device (sky&dvd rec.) to the TV separately, I would simply hook up the sky to dvd recorder (connect the sky output and dvd recorder input), and then connect the dvd recorder output (must be called "play out") to one of the available recorder inputs (which could be a dvr, an empty tape input, etc)of your amp. However, you'll still have to establish a feedback between your dvd recorder and your amp. Therefore, if the dvd rec. supports it, you'll have to hook up the rec.out, which is on your amp.,to on your dvd recorder. After all these audio connections, you will only need to make a video connection among the sky, dvd rec., and tv. Get a video cable to hook up the sky video output to your dvd recorder's video input, then do the same thing between the dvd recorder's tv output and tv.
