Onkyo TX-RZ70 11.2CH AV Receiver - Official Support Thread

My Onkyo receivers do take a moment to output audio and the momentary delay coincides with the changing of the channel input/output display on the front panel. Once the input signal is recognized and processed according to the selected sound mode, audio is output and the channel indicators light up.

A recent software update for newer Onkyo models also changed the Power up sequence and resulted in a bit of a longer wait for audio output when coming out of Standby mode.

There are a multitude of items to check when transmitting data over HDMI 2.1 ports from an input source device into a receiver and out to a TV. Data transmission times will vary a bit based on the combination of devices and HDMI 2.1 settings in a system.
ok thanks! i really only noticed it when running test files. switching inputs takes a little longer. my x4400h is a little faster on switching and almost instant on audio output when running test files. still debating if i want the rz70 or x4800h.

There is one sticking point about ALL the new Onkyo receivers. If one has a speaker configuration containing Surround Back speakers, Onkyo receivers will output the Surround Channel information contained in Dolby 5.1 tracks from the Surround Back channels when using a Straight decode of the 5.1 signal.

Many do not mind the automatic up mixing of Dolby signals by the Dolby Surround up mixer in their 7.1 or more channels systems. But, some do not like up mixing 5.1 signals. If the 5.1 signal in play is Dolby, Onkyos will output the Surround channel information from the Surround Back speakers.

Outputting the Dolby 5.1 signal as multichannel PCM, if possible based on the device used for playback, would result in the Surround channel information being output from the Surround speakers.

The RZ70 and X4800H will each have their own quirks concerning DTS signals compared to older models of each brand. There will be some channel output issues with IMAX DTS signals as well.

If I was going to upgrade today and add two more subs to make a total of four, I’d probably get an X4800H to play with the Subwoofer “Directional” mode. I think it is still on sale for around $1,800. The X3800H is also on sale but I hate that front display.

yea i sent the rz70 back and im testing the x4800h. the rz70 sounded less dynamic and more compressed using dirac but it timbre match my speakers really well. it sounded a bit brighter to me in direct 2 channel than the x4800h. it also sounded a little less detailed to me in some of the test tracks than the 4800 but that could be something to do with dirac and my untreated livingroom. i couldnt really tell a difference in power between the 2 with my revel f36's.

i like 5.1 upmixing with dolby surround. thats something else i noticed is my x4400h and the x4800h sounds more immersive upmixing 2 channel with dolby surround to my 5.2.2 system. i do think most of that is probably caused by dirac over eqing but im not sure.

Hi all

I know this will be controversial given the background chat around power handling and the RZ70 when handling 4ohm speakers. I'm currently running Jamo 606 floor standing speakers in a stereo + centre speaker set up with my RZ70. They are bi-amped. I have an opportunity to snag Monoprice Monolith T6 floor standing units at an amazing price to replace the current. However, that are 4ohm speakers. Now, the RZ70 should be able to handle these in a basic writing configuration, but I wonder what you think about bi-amping the Monolith speakers?

Thanks, G

That is hard to know without knowing your listening habits and distances. Just keep in mind, regardless of whether the amp is rated for 8, 4 or even 2 ohms (none can do that so just saying..), power not needed/used will not affect audio performance. So, you need to figure our what your need is, in this case, more likely current, in your applications. Once that's done, you can answer your own questions that are "power" related.

The RZ70, like most if not all AVRs are not really rated for 4 ohms, as they expect you to use the impedance setting.

See manual p.40:

Based Audioholics review, I would think the Monolith isn't that hard to drive, but again it depends on factors I mentioned above. For example, if you listen to a maximum level of 10 dB below reference, that would still be quite loud to a lot of people, from say 10 ft, the RZ70 should have no trouble meeting their demands unless you listen to certain contents for extent period at higher level, then you should use an external fan.
