Question about Audio & Video Receivers

Help urgently required.....

Hi, I have a technics stereo which is 7 years old. It is the silver stack system with surround sound speakers (5 in total) It was working fine until 2 days ago, the fault is that the red standby light is showing when plugged in, but to press the actual power on button, it doesnt turn on. Usually, a faint 'click' can be heard when I press the on button. Remote control wont get it to work either. The on button on integrated into the tuner/amplifier section of the stack system. The model no. on it is SA-EH770. Please help, i'm missing it!! Samantha.

The click you hear is the power relay. Normally that would be followed by amother click of the speaker relay. In this case, the output section is in protect mode because of a fault detected. This will prevent the speaker relay from turning on the speakers. This amp will require repair. I don't recall your specific model, but if it has discrete transistors, expect a parts cost in the $20 range. If it has a single output amp pac, then the part could be in the $65 range. Add in the local labor rate for the complete repair cost.

Surround Sound System Settings ---- Correct Time Delay Setting in Multi-channel Audio

A correctly set surround sound system can yield dramatic improvements to your
home theater sound or multi-channel music listening experience. In particular,
a correctly set time delay setting between the different channels is essential
for a realistic and unified surround soundfield.
Luckily, most of today's surround processors make setting the time delays
between the rear and the fronts a matter of a few entries in the setup menu.
Yet having a proper understanding of the principles behind correct time delay
settings is essential for the best results.
In this guide, we explain the principles behind time delay settings in surround
sound and show you how to adjust your surround processor or AV receiver for the
best surround sound field.

Time Delay Setting in Multi-channel Surround Sound Systems

Correct home theater speaker placement and properly balanced sound levels
between the different channels in multi-channel audio, while crucial, are not
enough to sustain a unified soundfield in a surround sound setup. A correctly
set surround sound system requires that sound from all the different speakers
reach the listener at exactly the same instant.
This explains why all fronts, left, right and center channel speakers, should
be set at exactly the same distance from the listening position. At the same
time, in a typical home theater setup, the surround speakers are closer to the
viewer than the fronts.

To compensate for this distance discrepancy, surround sound playback systems
apply a split-second delay to the surround sound channels.

Some DVD's sound fine whilst others have background sounds but no voices. I do have an old model TV that has mono sound.Would that cause it?


" Some DVD\'s sound fine whilst others have background sounds but no voices. I do have an old model TV that has mono sound.Would that cause it? "
Hi,
I wrote a short article for someone who had a similar problem a few days ago.
I will edit it for you so that it fits. Here it is.
Your DVD player should have output connectors in the back of it to plug your amplifier or receiver into. If you have a Stereo system (no surround sound speakers, or front center speaker) connect the DVD Audio Cables on the back of the DVD player to the STEREO (or MIXED ) Output Jacks. If it is connected to the Left Front and Right Front jacks of the "Surround Sound" output jacks instead of Stereo(or MIXED) then the dialog will be sent to the CENTER channel output. If you have no center channel speaker you will not hear it. Thus no dialog.
NOTE: In your case for the TV that is mono, here is the solution.
1 Connect a stereo pair of RCA cables (red and white "male" connectors at each end) to the Mixed or Stereo Output of the DVD player (NOT ANY SURROUND OUTPUTS).
2 Purchase an RCA type "Y" connector that has 2 female to a single male connectors on it. Walmart about 3 dollars.
3 Plug the single male plug of the Y connector into the back of the TV set's single mono audio input.
4 Connect the stereo RCA pair from the MIXED output of the DVD player into the Y connector that is now on the back of yourTV.
5 Run your yellow Video output from the DVD into the Back of the Set's yellow input.
That should do it. The sound should be clear and correct with dialog, effects and music.
Hope this helps,
Best,
Mark

5ch/7ch stereo in 5 channel mode


Front panel button engaged for 5 or 7 channel operation? Also check front panel rear surround speakers button is engaged. Should get you back to 7.1 unless you have changed the rear surround speaker setup for a 2nd zone, also be sure you have a 7.1 DSP setting enabled.

Can n ot get rear surrround speakers to work


On this reciever you have rear surround and rear back spkrs, if your using the surr back they have to be assigned if unassigned in the settings. If using rear surr spkrs change your surr field to 5ch stereo and your rear speakers will work.
There is no 7.5 unless you have 5 subs the 7 is the total number of speakers and the .1 is the number of subs in the system

My kenwood receiver has


If you are referring to the rear speakers, it is normal. The rear speakers are not supposed to get a signal as loud as the fronts or center.

A surround sound system was originally developed for playing movies and the rear channels are for effects. In most surround modes the center channel will always be the loudest with the widest range of audio signals.

I have been repairing these type of systems since they have been on the market, so I know a lot about them.

This Kenwood you have is like most surround systems and does not have a feature that you would obviously like to have, 5 channel stereo. Only a few surround systems have this feature and they cost much more than the Kenwood systems. Denon and Marantz both make one with that feature. In 5 channel stereo you get a full signal to all the speakers. All the other surround modes you get a much lower signal to the rear speakers.

So in closing, you do not need it fixed, there is nothing wrong with it. You have a common complaint that many people have who buy a surround sound system but are not fully understanding of just what a surround systems is supposed to be capable of
. This is something that the salesman who sold it to you should have explained to you, that way you could have purchased a system that would have better suited your needs.

I would be happy to give you more help if you would like, just let me know. As I already stated, I have many years of experience with surround sounds systems, in fact I own the exact Kenwood model that you have and I like it very much. It is about the best you can get for that price.

I have an Harman kardon receiver (avr 310) it only plays in left and rigth speaker with surround off . I try everything to make it work in other but it can't .


Surround only works from a surround source such as Pro Logic.
If you are useing a regular stereo source with surround off, the sound will come only from L/R speakers (and sub woofer if used)

Hi Linda,

It is showing two because the source of the sound that you are listening is probably stereo only thus only two sound comes out. You could try to change the mode to 5 channel stereo or prologic or dts-6channel mode in the surround mode to hear your sound in all 5 speakers. best thing to do is watch a dvd which would use all 5.

Regarding a/b yes if your receiver supports it which i think it does there should be place for it in the back of the receiver.

good luck
