Back speakers with av denon 1908

have the same model. just got it to work. but, struggling with one part. here's the scoop. 1. Plug your second zone speakers into the SURR BACK/AMP ASSIGN speaker outputs on the unit. 2. You need to "amp assign" the speakers to zone 2 by pressing AMP, MENU, select SPEAKER SETUP, AMP ASSIGN and scroll to ZONE 2 - this will force the sound to the speakers that you plugged in. 3 - Turn on Zone 2 (press Z2, press ON button on remote). Use the UP/DOWN arrows to select the input for Zone 2. I've only been successful in selecting USB and plugging my iphone in for zone 2. For some reason, I cannot get the SAT (cable box) to play in both zone 1 and zone 2 at the same time. But, I can get SAT in zone 1 and USB in zone 2. Hope that helps. Let me know if you can solve my issue...

You might want to review the manual below:

1) Make sure MASTER VOLUME is not set too low 2) MUTE should be OFF 3) Make sure nothing is plugged into the PHONES jack 4)Make sure the source program has a signal present - the inputs may not be connected to the selected source on the front panel (or try FM or AM for a source instead) 5) Check for proper connection at each of the speakers AND at the rear of the stereo. 6) Perform a microprocessor reset: a.Power the unit off, b. Press and release the "POWER" _while_ keeping both "Speaker A" and "Speaker B" buttons pressed. Once the display begins flashing in 1 second intervals, release both speaker buttons.

Hopefully, one of those steps will solve the issue. Please rate this reply if it was helpful - good luck!

Before we play taps and throw dirt on top of the Denon, perhaps a bit more triage is in order. I'm not certain who the patient is. Especially when you have "speaker issue" in the title. Are you saying there are some speakers that don't work ONLY with BluRay?

If it has NEVER worked the (unnamed) BD player or its cable(s) could be at fault, too.

What 'connections' are we talking about. HDMI, coaxial- or optical audio, 5.1 analog; to what input on the Denon assigned to what function?

Have you tried all audio paths out of the BD player? Is it configured to squawk in the right digital mode?

Do you have any other digital audio sources (CD/DVD) you could use to certify the audio paths that don't work with the BD player?

Did you try Denon customer care?

Hi you must put the amp into prolgic mode this is fed by a stereo siganal the rears will sound vague and hollow that's all you will get this willnot work with 5.1 or 7.1 good luck

On this reciever you have rear surround and rear back spkrs, if your using the surr back they have to be assigned if unassigned in the settings. If using rear surr spkrs change your surr field to 5ch stereo and your rear speakers will work.
There is no 7.5 unless you have 5 subs the 7 is the total number of speakers and the .1 is the number of subs in the system

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

Ron Digital audio will only reproduce in the surround area you will have to connect using analog connections in order to get that sound in the 2nd zone

the mani surround room should be connected to the front speakers A, Center, sub pre-out and surround.
for the other two rooms connect them to surround/back, go into settings and in power amp assignment assign the surround back speakers to the multi room.
once this is complete with your remote in the zone2 control mode you can play your sources in zone2 and control the volume also, if you have inwall volume controls set the zone2 volume to -10 and use the room controls.
To listen to the same source in both zones you will have to select that source in both zones

1-make a reset to your system.2-repeat your speaker setup.3-confirm that you assign your sysem for 5 chanell surround system.-4-change the cables between left and right front speakers if the trouble go to left channel you will have a problem in receiver itself-if the problem exict you will have a problem in speaker itself(cable or speaker)
