No sound from speaker B. Right speaker A ok. Appears to be an electrical disconnect at speaker terminal. When I move the terminal post, the speaker will temporarily engage. I removed covered and checked for voltage at the lead to the speaker terminals. Voltage was present on all speaker leads.
Thanks for help.

Hi, First of all check all the speakers. Maybe all the speakers gone out because of the loud blast. Also check in the tuner mode. Is there is any sound. If there is some problem in the avr then it will show the fault and will go into protection mode.
You can check the speakers with a battery from any one of the remote. Take the leads of each speakers and connect the lead to the battery terminals. If the speaker is ok then it will make a small cracking sound each time when you connect its wire to the battery.
There is a short either on the speaker wires to the speakers or the speakers are defective (some sort of a short or too low of resistance). Lastly, check to see if a stray strand of wire is not touch the left and right terminals. Any short in the network (wire, lack of insulation, staple, screw, etc. ) will cause the system to clip.
The spkrs sound like they are bi-amp spkrs, meaning you have multiple terminals on the backs of each spkr, the jumpers on the spkrs should be connected as such. Now you just connect the spkrs according to the Denon spkr conection diagram. Do not use the surround back unless you have 6 or 7 pair of spkrs
Denon AVR-1403/483One of the speakers when connected trips the units power off. Disconnected it and it works OK without that channel. Connected a different speaker and wire to that channel and it does the same, trips power off. It's acting like a when two wires are shorted. This is not the case as I have tried different wires and speaker. Not sure whats going on. Presently running system without that channel. Hope someone has an idea.
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! Cheers, solutiondoct
More than likely the protector circuit is getting activated... You can't go below 6 ohms on the surround back which means you need 12 ohm or higher speakers for outside (since the two outputs for surround back/zone2 are in parallel). As a simple diagnostic test, disconnect one speaker and see if the sound survives longer than 2 seconds.
First check the outputs at the output fets/transistors for any DC voltage. Reference your voltmeter to the speaker - terminal. If there is ANY DC offset, the amp is shutting down the outputs to protect your speakers from DC.
Is the power supply + and - 47 volts? If only one supply is there That is your problem because the supplies should be symmetrical.
Also look for any wiring problems from the amp to your speakers... any shorts? Try disconnecting all your speakers to totally eliminate any speaker problem and see if the relays still click. You should hear only ONE click when you first turn the amp on (delay of about 2-5 seconds). If they keep clicking the amp outputs are next.
Also, is there any indication on the front panel of what is failing?
