Try reversing the Left and Right inputs if the problem follows the left input it's in the left cable or feed. if the problem stays in the left side it is in your surround sound or amp.

Many surround amps have test tones to that go to each speaker to test if the wiring is good. If your model doesn't have them, use a THX rated DVD. This will have on a menu a THX test tones for speakers. If the connections are good, then some amps have the ability to switch off speakers. Check your manual to see if this is the case. If you have Surround signals going in to your receiver everything is set up right, then the only other cause is a power amp failure for the effected channels.

How do i connect my amp to my vizio tv there are right and left outputs on tv but only one input on back off amp


Typically you need an preamplifier between your tv and amplifier. you run one optical cable (or coax ) cable from you tv audio output to the preamplifier then you run audio rca cables from preamp outputs to amp inputs (2 for stereo 5 or 7 for surround). the preamp decodes audio and controls volume and surround modes.
If you have a cable box and need just simple setup for watching tv just run rca cables from your cable box audio outs to your amp inputs. you then program your cable remote control to control volume.

I am trying to hook up a RX-B503 amplifier to my KAWASAKI receiver. I have taken the output of the KAWASAKI to the input of the RX-B503 but I'm not getting any sound. I have talked to tech pro and they...


You're already playing around with it and trying to blow it up. Amps/receivers never feed back into other electronics in a continuous loop back to themselves. What 'output' were you trying to run to the the unspecified Kawasaki? Speaker, Tape Out or Pre-Out?

The RX-B503 is a receiver, so it has its own sources.

You don't say what you're trying to accomplish with the Kawasaki. Is it to drive more speakers, slaved to the TechPro, which is stereo-only by the way?

Use the Preamp OUT on the TP for volume-controlled STEREO programming to anything downstream.

Do you even have manuals for any of this?

I have a Yamaha AX-900 Integrated Amp that I puchased back in the late 80's. It still works great, with one exception. The left channel is not as loud as the right channel and I have to put the balance...


Hi...
The tone control circuit has "issues". Could be a bad interconnect or a failed pre-amp chip.
If you dont mind putting about $100 into it, get it looked at

After playing for a while my Sony Surround Amp cuts off and shows a PROTECT Reading in the window.


Sounds like the amp is protecting itself from an over-current situation.
This happens when the machine has to try too hard to get sound out to the speakers.
There are several possible reasons.
You may be using the wrong impedance speakers for the amp.
-some amps only work with 8ohm speakers
-some only work with 4ohm speakers
If you have a short circuit in the speakers or in the speaker wiring, that could cause the amp to overwork and go into protection.
If you connect up multiple speakers to the same single output of the amp you effectively short out the amp and cause it to overwork also.
Before troubleshooting, blow out the amp, dust inside can cause lots of problems with the electrical systems. Use canned air and do it outside with fresh air.
To troubleshoot :
1. check to see that the amp and the speaker have the same impedance number, either 4 or 8ohm. This is usually printed on the back of both. If they do match go to step two.

2-unplug all the speakers, add one speaker(left one) and test it for awhile to see if it goes into a protection mode. Next move that same speaker to the right side output and run it for awhile to see if it goes into protection mode. Repeat the test with your other speaker, moving it to both outputs(L&R) to check if it works. If the amp fails with either speaker on either output, you may have a mismatch of speaker and amp or a bad amp. If you have only one speaker that causes a protection, then you have a bad speaker or it's wire. If both speakers go into protection, get different speakers and test again. if it works for all of these tests, go to step three.

3.hook up both the left and the right speakers to the amp. be sure that the wires are stripped cleanly and twisted tightly, if you have screw on outputs that is. Test for proper operation. At this point you should know if there is a single speaker causing the protection or if it is a amp malfunction.

I don't have any instructions so i don't know how to hook up my speakers and the t.v for surround sound i have a carver avr 100


You should be able to online to the manufacturer of your products and download manuals. However, I will try to help.

Connect the sound output cables from your DVD player including, left/right(white/red) as well as the Coax output/input if your DVD and your Carver each have this feature for enhanced sound on certain DVDs, and connect to the matching DVD inputs on your Carver.

Then, connect your DVD video output either by use of your RGB(RED/GREEN/BLUE cables or an S Video cable to your the matching video inputs on your t.v.

On the back of your Carver, you will find outputs for left and right speakers, connect to the left and right speakers with proper wire. Make sure that the 2 conductor wire is connected with the same side(polarity) on all speakers for the best sound quality.

You will also find rear channel left and right outputs on your amp, connect those to your rear right and left speakers.

Connect the center channel speaker to the center channel speaker output on your amp.

If your Amp has a sub-woofer output and you have a subwoofer, make the connections on that as well.

Test all of the speakers with a feature that many amps have on the menu using your remote, simply called test. if all speakers are connected correctly you will be able to hear each one as they are individually tested by the amp. Hope this helps out.

Dear Sushant,    I do not think your use of an equalizer has caused any problems.  I will explain the proper use of the source/direct button.  This button's function is to monitor the output of a recorder connected to the record outputs of your amp.  When this button is pressed on the sound going to the speakers comes direct from the "source" (cd, radio tuner, phonograph etc.) when in the off position you can monitor the recording of whatever source is being recorded via the tape deck.  This switch must be off to record through the amps record outputs.    To test this, put a blank tape in the tape deck, choose the source as phono and place the dec in record/pause.  With the source direct button pressed on you should hear a change in volume when moving the amp's volume knob only.  When source direct is off you will be able to hear the output of the tape deck, so adjusting the tape deck's record level will also affect the volume coming out of the speakers.  more record level in/ more level out.!    Below is copied from page 9 of your user operation manual for Marantz's explanation of the source/direct button.  image.tiff
best of wishes, Michael Mittelsdorf

SOUND FROM YOUR SURROUND SPEAKERS COMES BY BECAUSE OF PROCESSING THAT TAKES PLACE IN YOUR SURROUND CIRCUITS. IF THE SURROUND MODE IS ACTIVATED AND U GET NO EFFECT AND U SURE YOUR SURROND SPEAKERS ARE OPERATIONAL AND FULLY FUNCTIONAL. THEN THE PROBLEM LIES WITH YOUR SURROUND DECODING IN YOUR UNIT. REFER TO QUALIFIED SERVICING AGENTS.
