20 Most Recent Denon AVR-1804 Receiver Questions & Answers


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.

I have the sample problem with my Marantz SR5300. Luckily I found a kind of KIA7915PI with metal backplate and I attached a small aluminum heatsink to it. So far so good.

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.

Not much information is provided but generally speaking a sync problem when playing back is not a problem with the amp but a problem with the source file, especially if you are playing a downloaded file. If you are playing a DVD this should not happen. If it is happening with a DVD, please provide further information.
Cheers, Don.

I connected by Roku to a Denon 1804 Receiver this way:- I plugged the cable that came with the Roku into VCR2 input jack of the Denon. (I used VCR2 because it was available).- Using the remote from the Denon, I made sure the slide switch was on "Audio." (See page 20 of Denon Manual).- I pressed pressed the System Setup button- *System Setup appears in display of Denon- Using the cursor buttons I scrolled to menu Digital in Assignment- I set Menu item 16 Coaxial to VCR2 since that was the input jack I used for the Roku. - After making the selection press the CH Select Enter button to save- To exit the System Setup press the System Setup button again- When using the Roku, select the input source as VCR2 (or whatever jack you used). You should now have sound through the Denon.The most important step is to read the Denon manual starting on page 20

If the speakers work with test tones this has nothing to do with them and all to do with your attachment and setup of the sources.

Stop guessing. Have you looked at all the manuals?

The other devices you're inquiring about are not named in your post. Name the makes and models first, then we'll look for the manuals. Then (maybe) find a solution. You could run them by the manufacturers' support sites or these guys...

This could be multiple issues and needs to be diagnosed on site.
Dirty power can cause this, nicks in any speaker wire, faulty speaker, faulty receiver, etc.

Some kind of ground potential difference between the TV and the AVR or perhaps it's a badly shielded cable.

Considering the multitude of variations you may have connecting the TV video and audio to the receiver it's hard to pin it down, but try removing all cabling between them and that should silence the hum. Add any cable and see if it comes back. Disconnect it. Test each cable the same way. At some point a single cable might be implicated. Replace it.

Also consider routing of any analog audio cable near power cables, the TV or other sources of high voltage and magnetic fields. I have a known problem when my overhead dimmer-controlled track lighting is on. Food for thought.

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.
