Question about Denon AVR-3805 Receiver
I have a pair of speakers in my kitchen that I used as speakers "B" on my old reciever, now with this Denon I thought I could put them on one of the Multizone channels and send a different audio source to them? When reading the instructions it keeps talking about a 2nd amplifier on Zone 2 or 3. I just have speakers, can I just hook up speakers to Zone 2 or 3 and power them from the Denon?
It sounds like you have a bad speaker on the zone 2, or you have the speakers connected improperly.
When you engage the zone 2 a relay clicks and the speakers then become part of the amplifiers circuit.
If the problem was in the amplifier, it would go into protect mode without even having speakers connected to it.
If the speakers all check good, you most likely have the wrong type of speakers, meaning the impeadance is too low, or you have too many speakers connected to it.
On the back of the Denon, you will see right around the speaker output jacks, what ratings the speakers should be. If I remember correctly, it says 6 ohms or more when using only "A" or "B", and it says 12ohms or more for "A" + "B".
If you have two 8 ohm speakers on the same speaker jack you now have a 4 ohm load. That is below the ratings and can cause the amp to shut down (go into protect). Since your amp shuts down right away, I think you have a bad speaker or way too many speakers connected.
I have seen many times when people will connect 2 or 4 speakers to the one of the outputs that are designed for only 1 speakers.
If you are using too many speakers you will need a speaker distribution box. It has a resistor network built into it so the amp never sees a lower impeadance than what it is designed for.
You can connect 4, 6 or 8 speakers to one set of outputs designed for 2 speakers. You do loose a lot of power to the speakers, but it is better than blowing up your amplifier.
If I can be of any further help, let me know.

SOURCE: Video off for Denon AVR-3805
please see if this tricky approach will work
1) go and download the file v.vtr
2) borrow a pocket pc with infrad red port
3) download the program vito remote and install that
4) use the file v.vtr and set up the device
5) the F1 command should be same as the "video off" button

If the Cd is wired digitally, it will only play through the main zone, because the Denon cannot convert down to RCA to cater for the zone 2. If you plug RCAs from Cd to Denon, Main zone will STILL play from digital, and RCA connection will allow zone 2 to play Cd from RCA input....same with dvd, Satellite Blah blah... no stress, any nasty RCA will do if you want to try before you splash out on really costly cables...perhaps you can help me...want to run AVR 2105 with 2 speakers in zone 2, manual says cant do it - only ably to surround back or biamp...dont want either, dont have stereo yet to try it out...did you have any trouble with that?

time to reset the microprocessor. See page 87 in manual.
1) switch off the unit using the main unit's power operation (small power button)
2) hold the PURE DIRECT button and DIRECT button at same time and turn the main unit's power operation on.
3) wait for entire display to flash in 1 second intervals
now the speakers need to be set up again but zone 2 will be working. i suspect a power surge causes the microprocesser to be corrupted. i put a power surge protector and have not had problems (lately).
