Unfortunately that brings me to the humming issue at higher volumes. Just as 1953 has stated in his post. While pausing a source, the hum becomes evident at around -20db on my HD-A2 and around -30db on my Motorola 6412. Both connected via HDMI. Unfortunately, those are the only numbers I have to reference the sound level.

I just wanted to thank you 1953 for taking this issue head on with Onkyo. I may simply return it, and opt for separates. I will continue to monitor this situation though as I look forward to hearing a resolution.


Thanks for the kind words. I'm sorry to say that as it stands there will not be a solution.

The very short answer is yes, in every conceivable manner.

I am new at this....I have 804 but the sound from the receiver is not warm. I did the speaker auto set up, did the speaker calibration and turn the EQ off but somehow it still sound a little off for some reason. Any suggestion is appreciated.....

Can you give a little more info. Good idea to list your gear in your profile so we know what you have.
What are you listening to? How is it connected? What is your speaker impedance set at on 804? How many ohms are your speakers? How many speakers are connected?
Check to see if the Digital Input is set to the correct input for the source. I had noticed once that I had connected my coax to one input but had it set wrong in the set up. But I was getting sound but not very good sound. Ex. DVD connected to coax 1 input and digital input was set to coax 2. When I checked it I had the wrong input selected. I don't know why it will output audio when wrong input is selected. I still don't know why. I have only one coax connected to 804. Maybe this is part of the hum issue that it picks up audio from other inputs who knows.

Go back in and turn off the EQ. On my 804 the auto setup made the high's far too harsh and it sounded tiny. Try turning off the EQ and see how it sounds.

Whoops, did not see that you had already turned it off. Sorry

Anybody pairing their 804 with Rocket speakers?

We're moving into a new house and I want to take this opportunity to upgrade my receiver (a Panasonic digital one) that I've never been convinced drive my Rockets well.

Anybody?

I have an old Onkyo 700 and it picks up audio from other sources sometimes IF you have REC OUT enabled. The solution is to turn off REC OUT.

guys, thank you for the responses.....

Sony DVD 400 disc connected to 804 with components for video and digital optical for audio
then component wire to Sony 42' projection TV(old) with no HDMI and as for speakers, I have 8ohms polk monitor 70 for front L/R, polk cs2 center, and a velodyne DPS-12 sub. I have set the front speakers to "small" or with crossover at 80hz, center crossover at 100hz and LFE at 80hz. The speaker impedence set at 6

Bill3508, I did turn off the EQ because of the harsh sound with the auto and manual setting of EQ but some how the sound is still not quiet there. Any suggestions on any of the settings to improve the sound quality is greatly appreciated....

Ughh... I just thought I narrowed it down to this receiver and I keep reading about humming, clicking and PS3 issues... Seems like the problems are starting to get resolved but I'm ont confident enough to shell out the money. Also, people have proposed bypassing the HDMI switching which in my mind defeats my whole purpose of buying an HDMI switching receiver to begin with and is an unacceptable solution (inferior sound, lower quality (no 1080p) and more cables).


I think I'm back to the drawing board.

If you have "horrible hum" return it. I've owned a lot of Onkyo amps/receivers over the years and that would be the first I'd ever heard of it.

NICK123 - you have 8ohm speakers but impedence is set at 6? Why? Maybe that's the problem...?

After the failed attempt to rid my 804 of the "Hum" and the fact that this audio interference begins at a very high volume range (67-74mhz) I decided to take a thorough look at the whole "run video through the AVR" scheme.

While we all have our own opinions I decided to consulant with the manufacturers of my AV hardware. Onkyo for the 804, Toshiba for my HD-DVD, Denon for my DVD, Sony for my HDTV and Directv for my HD DVR & HD/SD. To my surprise they all agreed that at this point in time the only true advantage in routing video through an AVR is cable consolidation. And, as I already knew, superior video quality is obtained when the video signal is routed directly to the television.

With my latest research completed I reconfigured my AV setup so that all video goes directly to my television with only audio routed to my 804. This configuration provides outstanding video and audio.

But, the idea that I paid quite a bit for less perfect AVR still eats away at me.

I sincerely invite you to respond with both comments and opinions.

please excuse my displeasure in this product, but whats the point of having an HDMI switching receiver that you can't use for HDMI switching? even if you lose picture quality a tiny amount.. I still feel cheated in this product.. has anybody had any luck getting theirs replaced by onkyo because of this fault?

I don't think the issue applies to all users. I haven't experienced the hum (yet) -- keeps fingers crossed.

I believe a digital audio cable (whether optical or coaxial) cannot carry the latest and greatest HD DVD/Blu Ray audio (like Dolby True HD, etc). Thus you need HDMI for that -- passed through your receiver.

The other advantage to HDMI switching is ease of use (not just less cables). You only need to use one input on your display (HDMI) -- instead of switching video inputs. So the only switching that needs to be done is via the receiver. Makes it easier to operate and to have others use the equipment as well (like wives and girlfriends).

As far as picture quality, I know the theory, but I have not been able to see any degradation when playing DVDs attached via HDMI directly to my projector, or when HDMI is switched through my 804, then out to my projector from my DVD player.

Walk, I believe the manual says that if your speakers are more than 4ohms but less than 6ohms the set the impedence to 4ohms and if your speakers are more than 6ohms then set the impedence to 6ohms.

I have no hum issue as the way a few things I have connected as described earlier.

Onkyo has offered to replace my 804 but I am not convinced that the new AVR will be HUM free. Likewise Circuit City will either fix or replace my 804. The problem with their deal is that my only other AVR choices are the Denon 987 or Sony STR-DG1000.

caesar1, it is great to hear that you are not having audio problems.

I am going to go out on a limb here and ask you to consider performing a wee test. The test is simple - Ensure a HDMI cable is connecting the 804 to a television. Ensure the 804 is connected to a powered subwoofer via the subwoofer pre-out input. With only the 804 powered up slowly increase the volume unit from min to max. Note the range of the interference, if any?

caesar1, thank you for pointing out the positive aspects of HDMI routing. I must admit that while I was well aware of those points I was remiss in my failure to give both sides of the HDMI story.

I would like to add to your first paragraph. Like HDMI, analog RCA audio cables can transmit HD audio. Of course, not all HD-DVD players offer both HDMI and analog audio transmission, i.e. Toshiba HD-DVD A2. Fortunately, my A1 offers both cabling methods.

Again, thank you for reply.

i've had mine for 3 weeks now with no problems to speak of. i notice a slight, and i mean slight, hum from the powered subwofer. but can only hear it when the volume is muted. it's so low, that once i turn up the volume to anything listenable, i can't hear the hum and/or it is nonexistant. honestly, i had a similar hum with my last rcvr. i think this is partly a problem with powered subwofers. they are similar to leaving a live mic in a room -- you always pick up some interference. remmeber, they are powered, so that current alone can cause a hum. it could also be improperly grounded line cables to the sub. i actually have a pc case fan mounted to the back of my entertainemnt center to draw heat out off the rcvr, and when the rcvr is muted, i hear the pc case fan louder than the "hum." and i consider myself to be a very picky user. i have high expetations for all my equipment. if there were an unusual hum, i would return this rcvr in a blink. in any case, i can't speak to the rest of you, but for me, with my particular 804, i see/hear no defect. it works perfectly (thus far, knock on wood) and i'm very happy with it.

Okay, I did the test as you instructed: receiver on only. HDMI out from the 804 is attached to my projector (my TV in this case). 804 is and has always been connected to my powered sub (an SVS PB12-NSD via the pre-out). Note that I have the sub set to always be on too -- as opposed to automatically come on when it senses LFE. I heard absolutely nothing at all when the volume was turned all the way up (to +5) -- and nothing anywhere in between. Not a peep, not a buzz, not a hum. Dead silence.

However, I then powered on my DVD player (which is the source my receiver was set to). With the DVD player on (no DVD in it though) and the receiver set to DVD source (which outputs via HDMI, through the receiver, to my projector), I did hear a slight hum, only as the volume approached reference level. This hum was from all of the speakers, not just the sub. The hum was not audible from my listening position until about -10 from reference. Although if I tried real hard I could possibly hear it faintly starting at -15. Realistically, it did not appear that this would be audible during actual playback of a DVD (indeed I have not noticed anything out of the ordinary when watching DVDs) -- even though my typical listening volume is -15 to -13.

Is that the hum you are referring to? Or is it something different? Is your hum only coming from the sub?

This hum was from all of the speakers, not just the sub. The hum was not audible from my listening position until about -10 from reference. Although if I tried real hard I could possibly hear it faintly starting at -15. Realistically, it did not appear that this would be audible during actual playback of a DVD (indeed I have not noticed anything out of the ordinary when watching DVDs) -- even though my typical listening volume is -15 to -13.

Is that the hum you are referring to? Or is it something different? Is your hum only coming from the sub?

Mine comes from all speakers also. I have the same exact issue.
It used to be worse. I had front left connected wrong on back of 804. When I corrected it the hum was not as noticable. I became aware of this when I was playing around with the movie Cars. I ran the THX set up. It actualy told me my LF was out of phase.

I am very unhappy with the hum period. I paid for what I thought was a decent AVR
with great features for todays components. I now look at it as defective piece of gear.

This probably has nothing to do with it the hum. But Im interested in those that dont have hum.

How long are your wire runs to each speaker?

Those with hum. How long are your wire runs?

I will post mine tonight.

If your hum is as I described, I dont' think that's a defect. That's normal with almost all a/v gear. You can't turn up the volume to almost max and not hear something.

Do you hear the hum when actually playing DVDs at normal listening level?

So -- lemme get this straight -

This bad boy will upconvert all video inputs to HDMI?

So I could run all my equipment to the 804 and then a single HDMI cable to my projector and I'm good to go? True?

If that is true, I notice no DVI input. My cable box is DVI out. Is anybody doing a DVI-HDMI cable into the 804 with success?

Not at normal level no as in normal its different for each input.
volume levels:
A1 HDMI set to auto usualy at -35 to -25
A1 Mutichannnel at -15 to -10
A1 Coax bitstrem at -35 to -25
H20 HDMI at -35 to -25
I nottice it more with analog.
But when Im watching a great action flick I like to crank it.
The sub is what I hear. But I have stated before. I can hear alot of unwanted hissing pops, ticks, and hum from all speakers when I get within a few feet from them.

The fact is there should be no hum from sub. Friend of mine has no hum with his A1. He uses analog and has a yammy with no HDMI. His sub is silent like its not even on.
Thats how it should be IMOP.

I agree.

I definitely hear no hum with my sub. I only heard a low hum as mentioned in the test above. I play all my DVDs very loud (-15 to -12 from reference level). Sub is actually calibrated hot -- about 5 dbs hot.

I would have noticed a hum during quiet or silent scenes in DVDs. I have not. I only noticed a hum when doing the test with the DVD powered on, but no DVD playing. The hum was still not very loud -- and not till -10 from reference did it stat to get noticeable.
