Denon UD-M50 amp/3 cd changer




By RPRP on Dec 30, 2007

" "
Cd auto changer reciever. have had 5 years or so but hardly used. Volume started to independently/ spontaneously increase rapidly to max volume today when on moderate volume setting. Turned unit off. When turned on again, the same happened. Pattern repeated again a third time after having played normaly for 10 minutes or so.

Any explanations and, ideally, solutions?
Same problem here with my Denon UDM50 - occasionally the volume control increases wildly / fluctuates when turning the knob anticlockwise. Remote control volume unaffected. Occasionally one speaker side cuts out - I believe this to be a related issue. Also interestingly, we had a carpenter in to fix our windows and he said he has a similar TEAC unit (same unit, different fascia???) with exactly the same issue. Would be interested if anyone has successfully found a solution to this....!

Same Problem

-   I have the same problem - the volume just spontaneously increases up to full for no apparent reason - it was a bit unsettling the first time. I have a friend who also has the same unit and this has happened to her a few times.

I'm sorry I dont know what the cure is, it happens about once every three months, just thought you should know you are not alone!-   Guest
