Disconnect speakers, turn the system on, if its ok check speakers, impedance could be too low

    Thanks, ecnx1. But I did already try this. About 3 seconds after power up, the red light flashes and then the unit shuts down. I have read enough about these problems to have narrowed it down to the thermal protection circuit. I have the ability and means to make this repair myself, but can not get my hands on the schematics. l hate flying blind...

SOURCE: Kenwood:1090VR Cracking sound from front speakers

There are poor solder connections somewhere on the board. Usually these are at the voltage regulators where there can be some heat. Look for 3-legged transistors attached to small metal heatsinks, If you can solder, resolder the pins on those parts. Also look for any connections that appear to be grasiny or have rings and resolder them too.

Keep us posted.

SOURCE: 'protect' blinked and then no sound or display

Disconnect the outside speakers "at the speakers" then turn back on. If the problem persists, disconnect the speakers at the back of the receiver and try again. If the problem stops "at the receiver" check your terminals and make sure no braids are touching each other. If the problem stops when you disconnect at the speaker, chances are good it's a bad voice coil from moisture. Most "outdoor" speakers with a brand name on them have a pretty good warranty. Good speakers have a 10 year warranty and the manufacturer will replace. If you still have an issue, post a comment and I can help you some more

SOURCE: my kenwood av surround receiver vr-209 is turning

Disconnect all speakers at the receiver, then turn it on. If it still cuts out, it's a power supply, capacitor, or transister issue and will need to be serviced. If it stays on, re connect speakers one by one and turn the receiver back on until you find the problem wire or speaker. Once you find the wire or speaker that's causing the problem, disconnect the speaker wire at the speaker and turn it back on again. (Make sure wires are separated) if it still cuts out, check the entire wire or replace it. if it stays on, check the speaker with a meter for a short. If your not comfortable with doing that, any electronics shop will generally do it for you for free. This is the most common problem among all brands of receivers. Wires get crossed and short, then short the power supply. Hope this helps. If you need further help troubleshooting, post a comment and I will be glad to help.

I have 1 center channel pre-out on back of my kenwood receiver. how do i hook it to the inputs on onkyo m-282 amp and then to center channel speaker?


Unfortunately can't connect it that way. The pre out is only meant to go directly into an amplifier that has all of the same inputs (front/rear, center and surround), not a standard receiver. (Pre amp to amp only, not pre amp to receiver) If your Onkyo doesn't have all the same inputs as your Kenwood preamp has outputs you will just use your standard left/right outputs from the Kenwood to your Onkyo input (CD, Tape, Phono,DVD etc) then use the outputs (front/rear, center and surround) from your Onkyo receiver and connect directly to your speakers..

No sound output from Center and Surround speakers


the only time the center and surround speakers put out sound is when it has a surround sound source such as a dvd etc. and only certain sounds come from them as well.

Best amplifier for bose 901 VI speakers


By all-in-one amplifier that handles the surround I think you mean all-in-one receiver or preamp. Amps are just big dumb muscular power supplies for speakers.

The source control and digital decoding could be handled by a modern AV receiver with multichannel analog outputs for driving separate amps or you could get a digital AV preamplifier/control unit functionally like this Adcom. Prepare for sticker shock.

http://hdtvdreams.com/Adcom-GTP-870HD-7.1-Multi-Channel-Processor/Preamplifier-GTP870HD.aspx

Understand that EACH PAIR of Bose 901's will require its own DEDICATED two channels of amplification AND someplace to jack in its Active Equalizer - between the line level source and the power amp.

Conventional speakers can probably run off the receiver's amplifiers since they don't/can't/must not have the Bose Active EQ in line with them.

Having a single pair of 901's plus a passive subwoofer or two in the same room for accurate 6- or 7.1 surround would require at least four stereo amps or some combination that adds up to 8 channels.

In my own system I have a Pioneer VSX-36TX Receiver (with 5 potential channels of amplification for Left, Right, Center, two Surrounds) doing light duty as the control and routing center but ONLY driving the Center (two Kenwood 777's) and Surround speakers (Bose 301's). I have a Carver 5-channel amp pushing the Bose 901 Front speakers (100Wx2), two dbx Subwoofers (110Wx1) and the Bose 301 Rear Surround speakers (60Wx1).

You could probably get by with a powerful 2-, 3- or 4-channel amplifier to push the 901's and subwoofer(s) as I did. It's the cheapest way out if you get a decent AV receiver. Once you set up the levels and delays the receiver does all the thinking and controlling for you.

unit needs repair. Look at the b speakers. Conect a speaker or two to the B position. If you have no sound than your surrond sound is ok and the unit is bad. Sound comes directly into the b speaker and not threw the surrond system. My 6070 has a cold start up problem. no sound. time to purchase a new one. to costly to repair.

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.
