Make sure your turntable is grounded to your amp and that may take care of your problem. Most turntables have a seperate ground wire for that purpose. If you are having to turn your volumn up very high to get proper sound from your amp then your amp may not be new enough to accept a moving magnet phono cartridge and may be the old ceramic input type and a seperate small amp will be required. You used to be able to get these at Radio Shack. But I would look into the ground issue first as the most likely. Good luck.

Sound is really quiet with inputs


Hello. Please be sure that you are plugging your iPod into the tape in, or play, and not into the record out, or record. If you have these reversed, you will greatly lower the signal level going to the amplifier.

Hello, teac mp-211 plays music with distortion, S.O.S.....


Sound quailty is a function of the rip bit rate (higher = potentially better) and the transducers (earbuds (worst) >>> real speakers (best). Can you fill in the unknown piece of this and evaluate it on your own for how it affects the sound? You could also try feeding the output to other speakers.

If you drag the music files to another place, like a hard drive and play them you can determine if the distortion is inherent to the recording/rip.

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

Subwoofer problem


If you get your system up and running and hear an audible buzz or hum, the first culprit to look at is either the powered subwoofer or your reciever feed at the entry point to your system.

Random Shutoff of Yamaha HTR-5240 When Playing Movie DVDs


I found this answer up above and it working. I check my speaker wires and fixed some and it has been working since then. I copied the answer below.

First i would strongly suggest that you review your wiring, since the problem occurred after those change , It might also be just coincidence. When you are playing something(music) go around and listen carefully to each of the speakers, check for muffled or distorted sound, that could indicate a speaker or wiring problem. Of course the problem could also be in the receiver. The protection circuit in your amplifier could be acting up(too sensitive), in that case you might need the help from a local repair tech.
Hope this will help Good luck

Buzzing emitted by vsx-409


Could be the result of having DTS compatible equipment connected through the analog inputs on the VSX-409D. Noise and distortion will result as essentially the DTS signal is being played back undecoded. If this is the case you'll have to connect your LD or CD player through the digital connections (coax or optical) and set 'Signal Select' (button on front) to 'Digital'.

Distortion/noise and buzz in front left speaker


Try to see if the reciever will make the buzzing/noise without anything connected to it except power, and speakers. Tune into a local radio station and see if the noise continues. If the noise has stopped, then you know there is an issue with the player or cable.

Sony STR-DE475 - Sound levels dropping


When did this start? Did it ever work right?

How's the sound from your TV speakers by itself and from DVD? The same? Problem's in the TV.

If it's just the receiver doing it from both sources that's where we start.

Check the settings for dynamic range (ratio of loud sounds to soft sounds) in both your receiver and your cable TV tuner. Many devices have a setting sometimes called "MidNight Mode" to be used in the event you're listening while someone else might be sleeping or otherwise would be disturbed by the TV volume.

The assumption is that you will turn the TV down but that normally means you would lose the quiet programming in the background nosie of your home. Through the magic of dynamic compression the quiter sounds are raised to audibility while loud things like explosions and fanfares will be limited in volume. Depending on the design and whatever the broadcaster is doing to the sound themselves this could be anywhere from pleasingly effective to aggravatingly inconsistent with odd variations in the levels.

Hope this helps.
