In past Onkyos the on-screen display would stop working and it would just take longer and longer for the receiver and devices to handshake, eventually just failing to do so altogether.

Hello,

does anyone know if RZ840 supports ALLM (Auto Low Latency Mode) ? I just ordered one but i can't find any answer or link to that.

Btw, never had any problem with my good old NR616 but my RZ740 died exactly 13 months after purchase (no sound suddenly, totally mute on all sources).
I had noticed some audio cuts from times to times during months then the message final AMP SPEAKER and yes i had tried rewired it after 1st warning a few months before.
Now i have both a x2500h and x3500h from Denon but i want to replace the first one to get to 5.2.4 setup so i'm aiming at another Onkyo because Denon is missing an option that was really useful with my Klipsch subwoofer: BGC (boundary gain compensation)

I queried Onkyo about that, they told me none of their current AVRs support that feature. Since i have a Xbox One X, i think i'll just cancel it.

I think Denon x3500/4400/4500/6400/6500 have the allm feature.

The x3500 is maxed at 5.1.2 atmos while the x4400 is the lowest model with 5.1.4 (7.1.4 with extra amp) capabilities

Yes it does, I have a x3500h in my other room. I'll have to look for a x4500h.
Seems like Denon tries to give more features even through firmware upgrades judging various threads here.
I'm disappointed by Onkyo for this

So I bought the RZ840 and that's coming from a TWO WEEK OLD RZ830 that threw sparks after the thing decided that it was going to only see incoming signals as 1080p. But dammit if I didn't like the way the 830 sounded so much that I pulled the trigger on the 840. And I couldn't happier. I will be doing a pretty in depth review of it here in the next week or so. But to cut things short, the new HDMI boards works absolutely great. I have had no issue with it at all and it just works and works solid. This is coming from a Denon 930h that I just wasn't happy with from the get go really. I was hoping that the RZ830 was going to have had the dreaded HDMI issue that have plagued Onkyo for the better part of decade, fixed. But that wasn't the case and I was hugely disappointing in it. But really, I will go in deep on this machine here in a bit when I'm done with compiling my thoughts on the thing. And its really because I think it may be lead to the comeback that Onkyo needs and I am super pleased about it. My set up is pretty decent with an 65" OLED C8 and full 5.2.4 configuration, it's running off of a beast of a dual computer setup for game capture for my YouTube, with the gaming machine having an 8700k and a 2080ti and the capture rig with a 7700k and a 1080ti and an Avermedia live Gamer 4k both with 32gb Ram. That setup was having some pretty nasty issues with the RZ830 but never with the Denon 930h. And now no issues whatsoever with the RZ840. Also using a X-700 from Sony for the UHD Blu-ray duties and collecting dust is my Xbox One X... So it's pretty elaborate and the RZ830 just couldn't cut it and I was sore about it so I'm really glad that this ne s working because I've been a huge fan of the Onkyo sound for a long time, but that HDMI crap was killing my love for them for about 10 years. And this RZ840 is beast AF. But I will, for real, leave a real review on it for people that may actually be interested.

tx-rz840 rocking so far

Just got my RZ840 - replaced a Denon 3311CI that was doing a decent job but missing the modern amenities of streaming audio etc. I have it hooked up to B&W603's for the fronts, HTM-6 center and 607 rears and the 608 sub (though considering trying out the 610xp instead for a bit more ompfh in the sub).

So far going from the older denon to the 840, it has really showcased having more power to effortlessly push those 603s. Also the pure direct mode sounds great. I upgraded my setup to the 840 also because i wanted something that auto-triggered from the Sonos app since I have sonos throughout the other rooms, and so far that automation is working great too (I had some weird setup dance where it wouldn't trigger if i had the onkyo on Cat-5 and the sonos on wifi (both on the same network) but as soon as i put the onkyo on wifi as well, the trigger from the sonos connect started working fine.

The only thing I am still trying to figure out is the HDMI-CEC power on/off sequencing - i have all my devices - TV, BD, and Onkyo set to trigger standby with the HDMI signal, but if i turn the onkyo off it doesn't turn the tv off, but if i turn the tv off it does turn the onkyo off and the BD off (they are connected from the ARC HDMI port <-> ARC HDMI port for the receiver and TV, and i've tried both turning the HDMI standby pass through on/off, doesn't matter)....anyway i'll fiddle around with that setup a bit more but worst case i trigger everything off from the TV. Overall really impressed with the sound quality and power of this unit.

That's exactly how it's always worked with my Onkyo TX-NR838. So I just control through TV.

Hi.
I have gotten my hands on a Pioneer vsx932 but planning to upgrade to this 840.
I was wondering if you can help me: when listening to the phono input, can you select the video source that should be going out from the HDMI to the TV?
Thanks in advance!!
I dont want to get the surprise this is no possible when its too late..

The spec sheets say that AccuEQ is a new version that now supports subwoofer EQ? Was that true during your setups???

Can someone with a better brain explain this to me? Mine tells me that adding anything to a heatsink *reduces* cooling efficiency.

Anodizing aluminum (addition of an oxide layer) increases the surface emissivity by a factor of about 17x compared to bare aluminum. Basically, it can more functionally radiate away heat.


The heatsink warms via conduction (direct contact) and only disperses the heat in 2 ways: convection and radiation. Anodizing improves the latter. Reflectivity and emissivity are inversely related. A shiny heatsink will reflect more and radiate less. An anodized heatsink will radiate better.


Emissivity matters way more on passive heatsinks (like in AVRs) than ones that use active fan cooling. It's why you'll see PC heatsinks with big fans without anodization.

Hi Chuck666. During set-up I did not have an option to eq the subwoofer or any other speaker. After setup I went into the Menu->Speaker->Equalizer Settings to eq each speaker individually (including the sub). If I recall on my sub there are 3 frequencies I can adjust which are in addition to the crossover frequency. Hope this helps!

EDIT: Actually 5 frequencies--25, 40, 63, 100, and 160 hz.

Not sure if it's something that they changed on later builds of the RZ830, but the 830 I have definitely has a black anodized heatsink. (Open Box (actually new), $480 several months ago.)

Also noticed Onkyo intl site page features the cooling fan over the heatsink, but the USA site doesn't mention it. (Haven't seen it turn on though, hasn't gotten hot enough to trigger it.)

I saw a note that the 840 is getting a firmware update for IMax Enhanced (so is the 920) but not the 830 apparently.
(Also saw the note on the 840's improved HDMI board/traces, etc, and they tout a Quad-core processor in the 840.)

I'd rather have an 840 of course, but still very happy with this RZ830 performance for the price. (Driving 7.1.2 - Klipsch RF-83s, RC-64, RS-62s, RS-41s - all crossed at 80hz except the RF-83s at 60Hz, RS-41s at 100Hz), PC-13 subwoofer. (I may add a small amp later to power the rears, to allow for 2 rear heights.) I had a NR3007 (55lbs) years ago, replaced by a RX3050 (less power but nice features), but this current setup has never sounded better. (Detailed and very tactile with lots of punch in this small/sealed room.)

Excuse the off-topic post, just wanted to note that at least some 830s have a black anodized heatsink.

@pixphipau I do not own one, but from what I have read, sounds like you are stepping down to a much more basic room correction solution from Dirac. However, if you have a treated room with a single sub there are many here who say it sounds excellent. Some even tweak it manually so take a look back through this forum and you can see some comments that might help https://www.avsforum.com/forum/122-g...t-onkyo-4.html

I am not technical enough to know as I have old Integra gear that I manually adjust, I don't have a dedicated theater and I don't have dual subs (yet) so I am not sure what makes Dirac better than ypao or audyssey or accueq or mcacc?

Lol..same here about Audyssey...I am selling my Denon 4300H to go back to Onkyo due to Audyssey.

Does the 840 allow you to: Select ALL Speaker Levels per Input? 932 only lets me to set Center and SubW.

Shxx! I read the whole f...ing manual.
It does not. I am very used to change the height speakes levels on every movie
Did it took too much work to add all the channels instead just Center and Sub!

No it doesn't allow you to change individual speaker levels via the Quick Menu. You need to go in to Menu->Speaker->Level Calibration each time to change the height, etc. speaker levels. The Quick Menu only allows for center, front, and sub level adjustments during playback.

Switching gears, applied the IMAX and Dolby height virtualization update via the net last night. Took ~10 minutes, was seamless. Now we just need a few more IMAX enhanced blurays to test it

My RZ840 arrives today and I'm excited to say the least. For the past month I had gone back and forth about what receiver to get. Fingers crossed I made the right decision. I'm visiting Hsu Research in Anaheim today to test out their speakers and subs. Will probably get a 5.1 system with their horns and two VTF-3 MK5 or 15H MK2.

Forgot to ask, should this be changed to the 'official' RZ840 page? I'm super giddy to try this out.

The RZ840 is a monster

I'm almost done with my review and I have to say that this receiver is the exact reason why I wanted to give Onkyo a try again. It is a monster and the sound is open and dynamic without being bright. The channel separation is crazy good and makes the sound imaging just go crazy around you and it's not muddied at all. I downloaded the IMAX Space Station documentary, and a few others but, the Space Station one actually has the IMAX Enhanced sound track with it and it is crazy, balls out good. When the rockets take off.... holy crap. I felt like I was getting pelted with the glass the rockets make from the super heated sand that's on the launch pad. It had me squinting my eyes and it had to have been around 110 sustained decibels from my T1's. I haven't really ever had an experience like that at home before. it was, to put it simply, just stunning. I have had absolutely no issues with this receiver. My review keeps getting a little longer every time I listen to the damn thing but I'll get it out here soon.

Yup, my 830 crashed and burned in two weeks, but it was enough to tell me that I wanted to stick with Onkyo. As far as how they sound, it's almost identical with the edge going to the more full sound of the 840, although once I got both of them dialed in, they are almost the same.
