Looking for advice on resolving this issue.

 

I'm not getting any sound, or very little sound, through my left front speaker.

When I send the test signal around my speakers, the left hand speaker sound comes out of the RIGHT speaker and when I get to the right speaker the sound correctly comes out of the right hand side speaker again.

As I thought the unit has a fault I send it in for repair but they could find no fault, all channels going to the correct speakers.

Just got it back today and I still have the same issue.

 

Little bit of additional info on my setup.

My hi fi and home cinema are combined, the hi fi makes up the front left and right speakers of the home cinema.

The stereo is playing perfectly without any issues so the amp driving the left front speaker is fine.

I have one two channel amp that drives these and an additional 5 channel amp that drives the center and 4 surround speakers.

The center and surround speakers are all working correctly.

My hi fi pre-amp has an a/v bypass option which I use and it connects to the Denon left and right front speaker inputs.

I've tried reversing the pre-amp's av bypass interconnects into the Denon AVP to see if all the sound would now appear on the left speaker. This did not happen, still no sound from left speaker and both left and right test tones are still coming out of the right hand front speaker.

All interconnects are balanced cables.

 

I've been through every AVP option without resolving the issue.

 

Any advice to resolve this issue would be greatly appreciated.

1- How can all interconnects be balanced cables? The Denon does not have balanced inputs, does it?


2- Is the test signal generated by the receiver, or are you using an audio signal generator connected to one input at a time? You need to use a signal generator connected to one input at a time. If you do that, and the problem persists, then it is probable that the receiver is defective.


3- To prove for certain that the receiver is or is not the problem, disconnect the preamp and amplifiers and test the receiver BY ITSELF connected to 5 speakers. If it works properly that way, there is almost certainly a problem with your interconnects.

The Denon AVP has balanced outputs, which is why I bought it as my amp has balanced inputs.

I was using the Denon's test tones where it outputs a test tone to each speaker.

I've been dealing with Denon tech support and my amp's tech support. By trying out different cabling options the problem has been located with my stereo pre-amp. It uses an av bypass option to allow my front speakers to be used as part of my home cinema system.

I've arranged for collection for my pre-amp to be shipped back to the manufactures for investigation and repair.

They don't understand how the pre-amp is doing this but hopefully when they get it on the bench they'll sort it out.

Thanks for the help.

I thought I was posting a new topic in the Deon AVP thread but I see I have created a new thread.

(I'm new to the AVSFORUM so oops, sorry.)

It has been a while since this was posted, but I have the same problem: no sound from left front speaker of Denon 1909. Interestingly, I have this problem when the Denon 1909 receives input via optical cable from my Sony TV. This TV's audio output and input options don't give me much of an opportunity to try alternative sound setups. I also use an RCA connection to the Denon 1909 from Chromecast Audio, and when using that I am able to get sound from left front channel. However, the Chromecast Audio does not play 5.1, which may be a limitation of the Chromecast Audio rather than the Denon 1909. I have switched front speakers and tried using double (A+B) amping the front speakers without being able to solve the problem. My belief is that the optical input to the Denon is the source of the problem. Changing the optical cable or using the optical input from VCR instead of the optical input for TV doesn't solve the problem. I could try to use older HDMI devices that I no longer attach to my system in an attempt to better understand the problem, but instead decided to buy an optical to RCA adaptor for about $15 as an experiment that might lead to a satisfactory solution. I'm awaiting the arrival of the adaptor. Anyone have thoughts on this subject? I do have the concern that by using the optical cable to RCA adaptor I may restore the left front speaker sound only to find that I am not able to generate 5.1 sound.

Welcome. There is a dedicated thread to post Denon 1909 questions.

I understand this is an older thread for a different model but I found it on Google while searching for my issue, and I found a way to work around it, so I thought I'd share my solution in case someone else might benefit from it. For no apparent reason my AVR-X3300W had the same exact symptoms (little to no sound from left), and I thought about using the pre-amp output to drive an external amplifier (or another receiver through the CD input) but then I remembered that it had a bi-amp mode, and since I wasn't using the surround back outputs, I set the receiver to bi-amp mode and connected my front speakers to the surround back outputs since in bi-amp mode, it sends the same signal to both the left and right and the surround back outputs. This way I can still have 5 channels of surround sound and still use the amp with a defective channel.

...I'm not getting any sound, or very little sound, through my left front speaker.

When I send the test signal around my speakers, the left hand speaker sound comes out of the RIGHT speaker and when I get to the right speaker the sound correctly comes out of the right hand side speaker again...
