I don't think the current HDMI spec can pass through 4 K yet?

Most Seiki reviews I've seen were using Display Port or Dual DVI connections to get 4K content into the Seiki.

I think this is the case but I am not 100% sure.

4K@24Hz is supported by the current spec.

Thanks for the clarification.

I'm thinking about picking one of these up and have a couple curious questions. My current Onkyo is pre-audyssey

Will the HDMI signal pass through if the receiver is off?
Can I manually eq each of my 2 subs independently since it doesn't have subeq or whatever?
If I use external amps for my LCR, can I then use the internal for the heights, side and rear surrounds?

1) HDMI can be configure for some type of pass through, check the manual for details to find if it meets your needs.
2) The 818 does not have Sub EQ, even Sub EQ does not EQ the subs independently. With the 818 you'd need to manually adjust the phase and level between you subs, as the 818 will adjust those as one.
3) NO, SB/FH/FW are are a singable between.

Hello,

Just "upgraded" my old Onkyo TX-SR805 for the Onkyo TX-NR818.

The Sound Quality is really the same no diffrence for 5.1 surround sound, its hears like the dialog (speak) is more clear
For Stereo music it is the same


Pro's (against 805)
Network interface / DLNA / Streaming / URL
HDMI 1.4
more HDMI (4+)
Design is better (my opinion)
EQ XT32
Zone 3
USB


Con's (against 805)
no more analog multi channel input
no more bass/treble control for zone 2 (BIG MISS !!!)
-1 component
- svhs connections
thx ultra 2 vs select 2 plus (power but not noticeble)
build quality (seems more robust) no plastic buttons all aluminium


my 2 cents

Thanks for putting your comments on here. I'm doing the exact same thing going from 805 to 818. I really really love my 805 and I was a little concerned about the 818 but with your review now I think it's going to be just fine.
post #6968 of 9458
ok guys, u just said no big difference. can you guys sell to me the 805? i dont want to jump on 818 with the same SQ with the lower version. dont wana waste some mulah.

I traded mine for a 9MM. And I think the 818 is so much better with the Odyssey multi EQXT32 and added hdmi ports

Sold mine already sorry was in the netherlands.

I like the 818 arc is lovley.
Hdmi passtrough on standby is only done wih one connection ffom hdmi selectable.
3d 24p all working like a charm.

The power condumtion is lower.
And the thx plus .. Extra loudness is nice.

Ps the lan connection to pc there is no way to authenticate so beware

Any questions just ask.

Hi 818 owners,

I know this question is out of sync but i hope somebody can help me with my problem. I connected subwoofer out of my 818 to my SVS sub. The problem is... there are some frequencies which are excited/increased that seems to be boomy. What can i put at the corners of my room to attenuate the frequencies? It's a living room.

Thanks.

Did you run the full Audyssey optimization or just the quick setup? Did you try different sub locations?

Also did you try different phase settings. Sometimes that can help.

I did a dull audyssey. The sub's previous location was in the corner of the room beside my fronts. I transferred it in between the fronts, but some freq are boomy. Is there anything I can put at the corners to absorb or diffuse the sound? A plant maybe or something that does not alter the design of a living room?

Thanks

I did. But honestly, i don't know what setting is the correct phase for my room. SVS has points in between 0 and 180, I only choose either 0 or 180. 180 has higher volume than 0 in my room. Will I also change the phase setting set by 818 after audyssey?

Is it boomy or are you hearing the pressurization within the room?

You can change the phase on the subwoofer itself or within Audyssey, both do exactly the same thing. There is no way to find the correct phase for your room other than experimenting. Normally you would try 0 and 180 degrees and see which is more natural. Also, as others have noted, you might need to experiment with placement of your subwoofer in different places in your room, assuming that moving it around is an option for you.

A plant does nothing to low frequencies. Passive low frequency absorber are always relatively large. Before going that route you first would need to measure where the problem you're perceiving is coming from.
A second sub can help a lot. Other than that continue experimenting with different sub and speaker (!) locations. Search for "sub crawl". Placing the sub behind the main listening position might also be a good idea.

One can't hear "pressurization within the room" as a detrimental effect.

What I meant is sometimes people get boomy confused with the pressure the deep bass can bring to the ears. When lfe drops low 15 as an example you will feel ear pressure. I don't care where you place the sub.
post #6981 of 9458
A couple of things to look for;

a) Did you set the SVS to 75dB before running MultEQ using the subwoofer level adjustment in the 818? What level does it show post-calibration for the sub?
b) Audyssey defaults to having Dynamic EQ engaged after it runs, you could try turning it off.

You don't feel ear pressure "When lfe drops low 15". If you do then there's a constant pressure difference between your middle ear cavity and the atmosphere.
What you probably mean is a level difference between the left and the right ear. Happens in regions with strong stationary variations in sound pressure evel. This is caused by room modes.

I guess your right. What I mean is with mid and upper bass you hear the bass but when its deep (ahh lets see how I can describe this) you hear it kinda echo or pulsate in the ear. Hard to explain.

Markus, could you explain this a little better?

Thanks

Room modes create a stationary field of dips and peaks in the frequency response across the room. When the room doesn't provide a lot of damping the level can change drastically between points that are just a few inches apart. If one ear is at the first point and the other at the second, a sensation of "pressure on the ears" is perceived.

Here's a simulation of a single sub in a corner. The two curves show the sound pressure level at each ear:

With Dr Hsu's test cd for example. Playing the 16hz track you can feel the ear pressure. He mentions that is normal when it is that deep.
So what you are saying if its not corner loaded then there will be no pressure?

No, that's not what I'm saying. For a room to work as a pressure chamber (this is a requirement for room gain) below the lowest room mode, the room has to be airtight. Most rooms are not airtight. Car cabins are a different animal. Furthermore you need a source that is capable of pressurizing such rooms. Closed subs work, bass-reflex subs or dipole subs don't.

What signal does that track contain? Might just be a normal room resonance you're hearing or a object or a wall resonating.

Ok so in a home it is normal to feel the pressure right? Not sure on the signal just played 16hz.

I still don't know what you mean by "feel the pressure". If one has a lot of subs that are really capable of moving a lot of air then pressure can be felt but this doesn't happen with just a couple of subs and in open floor plan living rooms.

Maybe wrong choice of words by me. Maybe deep bass is boomy instead and your ears feel it.
