Question about Onkyo TX-SR803 Receiver

Phantom backround sounds

Occasionally you can hear what sounds like "musical scales" or like a truck starting up and driving off in the backround while viewing television. They do not over power the regular broadcast sound, but they easy to make out, especially the "scales".

Re: Phantom backround sounds

Need more info. Does it happen while using other sources? (DVD, games, VCR..) if so, pause the source and see if the sound is still audible. if it's only on the TV source then MUCH more info will be needed.

No sound out of the pioneer vsx-1121-k

Try removing all the speaker and the HDMI connections; then use a headphone to listen to music from the tuner or a CD in stereo mode. Better in direct mode. If you hear your music correctly the receiver could be working correctly. If no music is heard, you may need to have it repaired professionally.
If you can hear music, connect the main FL & FR speakers and verify you can hear music that way, without the headphone connected.
If you can hear music that way, connect the center and rears. Try a mode that uses all channels to verify all sound channels are working.
Then, and only then start adding your HDMI connections.
Good luck

Im having kenwood home stereo system model no xd-v818 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,

Why do the volume numbers on old receivers start

This type of calibartion is known as a logarithmic scale.
The numbers refer to decibels below the maximum output of the amplifier section of the reciever, or decibels of attenuation (making smaller/quieter).

Without going through logarithim theorey, the logarithim (base 10) of 1 is 0. So if 1 is the maximum output of the amp, as you turn the knob down from maximum you are adding more and more attentuation to the output (relative to maximum) and so the loudness of what you hear goes down, even though the number on the scale is going up !

Most peolpe associate decibels with sound levels, but anything can be measured in decibels, so long as there is soemthing to reference it against.

Denon AVR-1403 connected to DVD can hear music but no dialougue!!

Check the center channel speaker and the surround sound audio settings. If you do not have a center speaker, it needs to be set to off on the receiver.

Rx-v563 backround music much louder than people when watching tv

I would check your center speaker wiring and setting. Then switch to a different audio setting (pro logic, theater...)

If your system is set up for surround and you dont have a center speaker that will happen.
Check the manual for best setup
