Question about Cambridge Audio Azur 640P Amplifier

1 Answer

Noise when i play my brand new cambridge 640 i get a high pitch sound similar to feed back that is noticable between tracks. It's less noticeable with dvds. I've checked speaker hookups and am using a new cambridge 640 cd player as well. I'm really frustrated since, i have checked my old cheap all in one stero and it is silent even on max. I'm using bose 301 speakers, also new and have checked the hookups several times but the problem exists with headphones plugged to the amp. It kind of sounds like a form of feed back so i double checked the plugs to make sure they are grounded well and are. Any suggestions would be welcome

What is making this 08 caliber 2.0L sxt cvt have a High pitched whining sound at idle and driving?


Possible bearing in one of the drive pulleys. I have changed numerous alternators for this noise. Take the belt off and start the car. If the noise goes away you know it will be pulley related and not transmission related. If noise goes away, spin all pulleys by hand to determine the defective/noisy one

Why would a brand new fridge make strange noises already?


Good Afternoon Friend,

I understand that your Frigidaire refrigerator, model# FFSS2614QS, is making a strange humming noise. Your new, high-efficiency refrigerator may introduce unfamiliar sounds. These sounds normally indicate your refrigerator is operating correctly. Some surfaces on floors, walls, and kitchen cabinets may make these sounds more noticeable. This could possibly be the compressor that you are hearing. Modern, high-efficiency compressors run much faster than in the past. The compressor may have a high-pitched hum or pulsating sound. Hope this is helpful.

-Best Regards-

The motor manufacturers do not offer cut-away or parts diagrams. Parts such as bearings are purchased thru power transmission outlets locally. Parts for the pump should be found at a local pool store that sells the equipment. You will likely need a new set of 203 bearings, a flange gasket and mechanical seal. All told, the parts should be less than $40.

High pitch sound in background


A high pitch sound while connected in the house is either a problem with the reciever or you are picking up interference from somewhere. However, the high pitched noise when using the unit in a car (especially through an aux. connection), is caused by the alternator of the car. This can be eliminated by connecting a filter in-line with the aux wire (much like filters are installed on the radio power line). The filter is essentially a low pass filter that filters out noise above a certain frequency. You may have to get creative and modify your aux. input cable (i.e. - splice it into the aux cable) in order for this to work, or you can just turn the volume down a bit - it should be less noticeable at lower volumes.

TV won't turn on, makes high-pitched clicking noise


Its a real good chance that the HOT (horizontal output tranistor) transistor is shorted if so the flyback trasformer may be bad also. the transformer will make a tick tick sound if it is trying to start.

TV makes high pitched noise


In 1080i the horizontal frequency more than doubles from 480i. This means that possibly the high voltage transformer or a linearity coil is occilating at that lower frequency.
