Denon AVR-1804 6.1 Channels Audio Problem


I have a problem with my Denon AVR1804 receiver. The receiver works only on 2 Channel stereo (Front Spealer) when I'm playing CD, DVD and radio. It wont work when I tried to use to 5/6 channel stereo, DTS or Cinema setting. All 6 speakers are not working when audio is set to 5/6 Channel stereo. I would apprecaite if somebody can give me idea how to fix this problem.

Thanks you..

Re: Denon AVR-1804 6.1 Channels Audio Problem

Make sure the input setting is set to 'Auto' while on those channels and not Analog.

Sorround speakers not working though connected correctly

Without knowing exactly what your problem is, perhaps you are not playing sound that was recorded in at least 5.1 format. A DVD or BluRay will indicate the format on the cover. The data is decoded and split into (for example) six discreet audio channels. Left front, Centre front, Right front, Surround Left, Surround Right and LFE (Low frequency effects) If you are playing a standard stereo audio disc, then the sound will only be heard from the front L&R speakers, which are expected to be full range speakers. You can, however choose an audio configuration that also provides a signal for the SUB (LFE) and even a pseudo surround. If you want more info I'm happy to help. Just tell me exactly what sound source you are playing and we can work it out.
Cheers for now, Don.

Zone 2 on my Denon AVR 1804 only works with an analog input. Apparently it was designed that way. WHY?

Because in order to use a digital input, the unit would have to completely power on. Zone 2 is designed so that it can be used with the main power off.

Denon avr-1804/884, speakers Bose vcs center, Bose acoustimass 5 series 3 speaker system, Bose 201 series 4. All speakers play in test mode, with tuner, dvd, phono, cassette. The left side speakers will...

You don't say how "TV audio" is entering the system.

My guess is you're using analog audio Out from the TV into an analog input on the Denon. One channel failing would probably be the Left Channel cable failing or not seated.

I always recommend bypassing the TV audio entirely if the programming comes from somewhere other than its own antenna, as TV audio electronics add nothing good to the process.

If you're using cable box, sat box, game, whatever, ITS audio is best sent directly to your Denon's specialized audio hardware - digitally, if possible, to preserve multichannel possibilities.

You could also run standard analog audio from the cable box to the TV analog Audio IN if you just want to watch news and weather on TV speakers without the Denon involved.

Denon AVR 1804

You need to get the manual and do some reading first. I couldn't find the AVR-1804 but the AVR-1803 is avaiable. It should be close enough to get you through connection and setup.

Denon avr-1804 its turns back after 5 sec

Disconnect all speaker wires on back and then turn on. If it happens again, it's most likely a power supply problem. If it doesn't happen again, it was probably crossed speaker wires.

Unit keeps shutting off

Protection circuit activating. Possibly a shorted amplifier channel or power supply fault. Take it to a Denon repairer

5ch/7ch stereo in 5 channel mode

Front panel button engaged for 5 or 7 channel operation? Also check front panel rear surround speakers button is engaged. Should get you back to 7.1 unless you have changed the rear surround speaker setup for a 2nd zone, also be sure you have a 7.1 DSP setting enabled.

Denon av receiver switches off

replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

Playstation3 and Denon AVR-1804

If you don't have a user guide, go to: From there, you can click on Support and search for archived will find a pdf there.

Of your five plugs, a red and white next to each other will plug in to the audio in on your denon (Red is for Right) I would use something like the VCR-3 pair on the left side of the rear panel. The other three, Red Green and Blue are for Video Component In on the denon; Use either Video-1 or Video-2 in the component section on the right half of the rear panel.

At his point, it will be best to look at the manual, because you will have to pair the two items together in the menu system. It takes a little patience but isn't too hard.

Good luck.
