Sound distortion on beomaster 3300

My Bang and Olufsen Beomaster has developed a fault, certain sound frequencies, mainly piano and vocals, become distorted. I tried a different pair of speakers but this did not cure the problem, do you have any suggestions ? Thank you, Albert

    the outlets in the back of the beomaster 3400 are a bit loose and i am not sure is that is the reason feedback is being picked up.

There is a defect in the pre-amp section of the unit. Without seeing it and taking a few measurements, I can't give you any particulars. A rough estimate for a repair wouldbe about $10-$25 in parts plus the local labor rate.

Hum created by Denon AVR-3300


Look for bad electrolytic capacitors. Swollen up on top or leaking, puffed out on bottom. If they look alright, you will need a capacitor tester to see if any have dried up. That's the first thing I check for hum.

Need power supply for bang & olufsen beosound 9000

However my experience of B&O is that the boards are well designed and are repairable at component level.
You will struggle to find a reasonable replacement, and if all the inductors are OK and there has been no big burn-up you would do better to replace the main capacitors and check the semiconductors. That will give you a good chance of getting it working.
A good electronics hobbyist or a local tv repair place might tackle the repair at component level.

Im having kenwood home stereo system model no xd-v818 ...in high volume about 80 the sound starts to distoriate and the voice is not clear..i want to kno wether the stereo deck is not able to provide...


Well, here is the situation as I understand it. Here is also some theory to help you out.
Your Receiver or Amplifier has a "scale" showing relative volume. Distortion always increases in speakers and amplifiers when you turn them up. If the sound is getting extremely distorted, the Receiver is attempting to operate above it's maximum output. The scale is an average, but because music recordings are often mastered at different levels, "80" may be too much. When an amplifier section of a receiver is over driven, the distortion (which you observed) will damage or burn out your speakers. Most likely the tweeter (high frequency speaker)
If you back off the volume, or turn down the output of the deck until the sound becomes clear, then that level, IS FULL VOLUME. Based on what you are saying to me, I don't think anything needs service.
There is one other very important thing I should mention to you
. When people use high powered equipment and initially turn up the sound. After a short time, the mind turns it down. What next happens is the reason professional musicians and sound engineers often have permanent hearing loss after a relatively short time.
What happens is that the listener and often the engineer running the sound board at a concert thinks the sound is not loud enough (when the audience is happy with the level) and turns it up. After turning it up, his mind (and the audiences') turns it down and then he thinks it not loud and then again turns it up. And up. And up. The only reason I'm not deaf is that I discovered this when I was building sound systems as a kid. I also studied about it. So please be careful when you play things loud. Permanent hearing loss starts to occur at the very high frequencies and rolls down from there over a period of time. Hearing loss can start to occur in just a few hours.
at 110 decibels. It doesn't come back. If you understand this, you'll keep your hearing.
I hope this helps,
Best Regards,
Mark

The sound is distorted and overwhelmed by static


Depends what the real problem is.

Is it related to certain sources only - try new or reseated cables,swap it to a different input; single channel - swap to isolate; or certain controls that have become noisy? A shop might be able to get some tuner cleaner into them.

Technics sax-710 receiver Nht sb-1 speaker developed a buzzing sound when playing, Kids may have over drove speakers(not sure) Replaced with nht supezeros now both speakers sound very staticy like off...


The speakers have buzzing sound because of damaged cones.
Over driving speakers, especially with heavy low frequencies, can tear the voice coil away from the cone.
Once damaged, only replacement will help
