Amplifier main channel non operational.

Hello Patricia, the Kenwood KM 209, is a two-channel stereo amplifier, you can only send two signals and amplify them, for example, Left and right front or Main audio output and you will have greater presence of frontal sounds
Audio output left and right rear or Surround, you will have greater presence of the rear sounds
It has the ability to amplify only two channels only
I hope you have clarified the possibilities
I send you the user manual, so you can observe the connection possibilities
Greetings Franco Dosil

Hola Patricia, el Kenwood KM 209, es un amplificador estereo de dos canales, solo puedes mandarle dos se?ales y amplificarlas, ejemplo, Salida de audio izquierdo y derecho frontales o Main y tendras mayor presencia de los sonidos frontales
Salida de audio izquierdo y derecho traseros o Surround, tendras mayor presencia de los sonidos traseros
Tiene la capacidad de amplificar solamente dos canales solamente
Espero te haya aclarado las posibilidades
Te envio el manual de usuario, para que observes las posibilidades de conexion

It sounds to me like you are using the receiver in surround sound mode and the click you hear is the center channel turning off. If you have another center channel speaker, try swapping that for the one you are currently using. If that doesn't fix the issue, then try replacing the speaker wire. If that still doesn't fix it, then the issue is probably inside the receiver and may be either an output transistor that is failing when hot or an electrolytic capacitor that allows too much DC offset when hot.

buy a optical cable and connect between PS to the amplifier or take the optical out from the TCL to the amplifier and select optical in,

Assuming running from a cold start,

it means protection circuit are activated.


If it runs hot, then turns off then it is thermal cause.

Simple solution could be disconnecting all your speakers

and power up.

If it runs OK, then reconnect one at a time to find the cause.


If disconnecting the speakers doesnt do anything,

these unit needs repair.


Start checking out power supply

Check the supply rails to the main amp ( B+ and B-)

and most important , check for DC offset voltage on all amp outputs.


Let me know if you need further assistance!

• Here is the manual you requested - KRF-V5060D http://manual.kenwood.com/files/B60-5676-00.pdf

• Hope this helps.

First of all, the KRF-V510 doesn't support direct powering of the Surround back but it does have a Pre Out to drive externally amplifed Surround back speaker(s).

The indicator for BS on the front panel is NOT an indication of speaker presence. It IS an indication of the INPUT presence of that channel.

During setup you will only see RB or LB ...

Page 17: IF you have something other than OFF set for Surrounds....
Page 17, step 9: AND you select something other than OFF if you have Surround back Speakers attached to the speaker connectors...

.. and complete the rest of the setup properly. You should HEAR the Test Tones on all speakers. If the Surround Back is inaudible you would need to investigate the external amp/speaker combination you're using.

Not a fuse. Go through all the setups and speaker definitions or maybe just find that pesky "stereo" mode switch and reset it to something that allows all the channels to operate.

MAKE SURE YOU HAVE ALL THE AUDIO SELECTIONS ON UR PS3 CHECK THE BOXES ,,IN THE AUDIO SETUP

ya am booster antenna of the am output u could try 1st or u saying teh kenwood limites u to 1620 max only ch >
