Question about Denon AVR-1907 Receiver
I have a denon 1907 that does not output to front left or right. I have eliminated all possible speaker and cabel problems. I suspect it is a tecnical setting issue rather than a fault.
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.

Well,i can tell you are not very focus,cause you posted Denon AVR-2807 with Bose AC 15 problem,but under your details,you put down AVR-5807!
First of all,it is so unfortunate that you are NOT able to gain and experience to true ability in sound for this wonderful receiver when you are using a dual tweeters speakers and expect to have good sound separation as a TWO WAY speakers(a tweeter and a midrange-for true high frequency and mid frequency sound separation.)
Secondly,you have defeated the audio configuration of the Denon AVR-2807,since all your speakers are control BY the Bose subwoofer.
Now,i could show you a way to hook this up,and it doesn't matter how you connect them, they are the "bicycle tires" installed with a "Porche"engine if you know what i mean.
If you want a good recommendation for your "beast",i will more than happy to show you the way!

Check in the amp section for a short on the output transistors. It may need a resistor or two also. I doubt that it would be in the power supply.

Help with hooking PS3 to a Denon Receiver. It worked before, but I had to move everything to a different location and when I hooked it back up the PS3 has sound but no picture. I have it hooked directly to the receiver with and HDMI cable (the receiver is hooked up to our cable box which is directly hooked to the tv via HDMI cable).
