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,
