Kenwood stereo control amplifier KC-206 doesn't work

Hi. Thanks for looking at my question. I have a KC-206 preamp which won't work. It lights up and the front controls appear to work but the digital volume indicated flashes 3 or 4 times when the unit is turned on then freezes at 4 on the volume scale. I got this along with a kenwood amp on ebay (I only needed the amp) and would hate to throw it away. I've seen on the internet where this might be a problem with the remote control (which I don't have). I haven't hooked the unit up to a power amp yet but assume this wouldn't change the problem. Turning the volume control knob does not alter the frozen volume position. Any help would be appreciated. Thanks. Ken I am having the same problem as you are here. I too purchased this unit as a whole system. But the remote sensor reading on the unit showed only at 4 like your. But I was able to hook the unit up and get low volume playing level from the power amp with the volume control turned all the way up. Using the equalizer control I was able to get additional volume out of the main amp. I hope someone can help us here.

    Exact same issue on my end.

    My remote works sporadically. At times it will change to CD player, AM ,FM, increase/decrease volume or whatever. At other times it doesn't have any effect on the amp. I have tried unplugging the system for awhile and this works for awhile but the problem resumes after awhile. I don't know if the problem is with the amp system or the remote. Anyone have any suggestions?

    I do not have the original remote to control all of the function on the control preamp. But what my Radio Shack Kameleon 6 in 1 remote. I have find that it will allow me to change the control preamp to the various input devices ( tuner, CD, video, tape monitor),mode. Plus I can vary the volume up and down with it. It sound to me like you have remote control device problem. I would check your battery in the remote first. Then if that don't solve the problem, I think there is an intermittent somewhere on the remote. It is more common to have problem there than at the remote sensor of the control preamp

I was able to use an universal remote control that I have, a Radio Shack Kameleon 6 in one remote control which I was able to program to run the audio portion of the Kenwood KC 206 control preamp. By adjust the remote sensor volume to max, I was able to get maximum volume out of the unit and drive the power section very nicely. Now I have to get up and manually turn the manual volume control for addition volume adjustment.

Hopefully Ken can find a remote that he can control the Kenwood control preamp the same way I did. Good luck here.

SOURCE: Kenwood stereo control amplifier KC-206 doesn't work

I found this thread when I was having the same problem with mine. Turns out that it's sort of a problem, but not really. Looking at the manual (which I found in another google search) I believe a "4" on the volume level corresponds to a default remote control setting. The remote varies the level between 0 and 10, but the "10" corresponds to the maximum volume setting on the preamp. So it actually works, it's just that the "4" reading doesn't change. There's probably a pin you can short somewhere to make that default to "10" which would be ideal. But I'm not sure where that is. Now on to my other problem. This particular preamp has a subtle 120 Hz hum...

How can i hook up my kenwood stereo control amplifier KC-105 to my GPX home stereo system?


If the GPX has an headphone output you could use the a stereo headphone jack to two phono cables lead. Connect them to the "aux" socket of the amp, or another suitable - not a phono or deck - socket.
You would have to keep the volume level low on the GPX unit, but apart from that all the functions should work.

I have a Kenwood KC 105 preamp and the volume is stuck on high. I turn the volume knob but it does nothing. Any suggestions?


Looks like you are going to have to replace the potentiometer, AKA volume control. It must be shorted out inside (probably) or knob came off the shaft. (doubtful)

Have a kenwood stereo control amplifier kc-206.. stopped working only clicks and no power. is it fixable? is there a fuse? all other parts work.


Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Kenwood control amp KC-206


Sounds like a low voltage to the front panel as the indicators are there such as control window illumination is dim and the remote does not function.
The remote sends an invisible signal to a detector just behind the front panel and if the signal from the remote is nice and strong from your new batteries in the remote then it must be the panel electronics.

I have found that if you clean the output panel of the remote with a damp cloth and the same to the front panel glass you may be lucky. Just Damp please not dripping in water!!!!!

If ypu keep the amplifier system very clean then this wont be the problem...But this action has worked on TV's with remotes...

If this doesnt work then a service is due....sorry....no quick fix..

Cheers YOU BEUT
