Onkyo RZ50 Power Output

[Isosevodes]

Can anyone provide information regarding the ONKYO RZ 50 power output driving 8 ohm speakers in a 5 Channel and 7 Channel setup? The only information that I can locate utilizes a "1 kHz Psweep test driving 2 Channels" which of course reveals 120 watts. Thank you in advance.

There is no simple answer as as all channels are not playing the same load. What speakers and is what is your concern?

Sounds like you're seeking an all channels powered rating? Those are only so useful IRL, too. Some bench testing will cover it tho. Maybe try this one for some more info https://www.audiosciencereview.com/forum/index.php?threads/onkyo-tx-rz50-review-home-theater-avr.30842/

I hope you have not bought it. That seems a really dreadful receiver. It power limits at higher power levels higher than about 20 to 30watts to 20 watts per channel to protect it. The DAC seems to be poor, especially when bass management is engaged. So it seems you will really have to use it in pure mode only. So no point in buying a sub. So you need full range speakers.

Amir does not recommend that receiver, and in fact gives strong recommendation to avoid it. If they are going to produce that sort of junk, they won't be around long.
With the DAC issues it is not even any good with external amps. Avoid junk and this is.

Thank you all for your input.

Wow that is terrible is it just this model or are all new ONKYO using this limiting feature?

I run the smaller cousin of the RZ50, the Integra DRX3.4 - basically the same as an RZ50, with slightly less power, and 1 less channel.

The amp had difficulties with my speakers, which is understandable, given my main L/C/R speakers all go down to 1.6ohm.

Although issues were experienced with the amp self protecting in lab tests at 5W@4ohm continuous - in actual use, browsing the Onkyo threads - no one has experienced this "nanny mode" issue.

In my case, I have used external power amps to handle my L/C/R speakers, while leaving the surrounds and heights (all of which are easy 8ohm designs) to the AVR's power amps.

Results have been excellent.

These are fantastic value AVR's, especially given Dirac Live comes built in, at no additional cost

However, if you want to try Dirac ART, then these may not be a good option - there has been no word from Onkyo/Integra about deploying ART in their range...

Personally I am giving them till January to make some sort of announcement, otherwise I will be looking at moving to Denon, just so I can get access to ART...

The protective nanny mode was triggered during a continuous 5W@8ohm test on ASR...

Are they being overly protective? possibly...

In the real world, no one on the various Forum threads has encountered this issue with their 4ohm speakers!

I did encounter some issues with my 4ohm (nominal, spec) speakers, but they have a minimum impedance of 1.6ohm.... yet even with that, my Integra DRX3.4 (which uses the same amp design, and has the same nanny protection circuit ) never went into "protection"

But consider:
1) 5W continuous would be way way too loud in my setup and room (typically my amps run at around 1W, with occasional rare moments of up to 4W, and momentary peaks that have never exceeded 16W)
2) There were clearly issues driving my speakers... imaging was poor, vocals/dialogue was confused - moving to an external amp resolved these issues immediately! - hence my assumption that it was unhappy with the low impedance.
3) I also tried it with my 8ohm alternate speakers (B&O Penta) and it handled them just fine!
4) Many people with 4ohm speakers participate in the forums and have never experienced the nanny mode protection circuit... so real life looks different from that specific lab test.

I think the whole "nanny mode" protection circuit thing, is a storm in a teacup, and should be ignored.

The poorer performance once bass management is engaged due to double decoding is a bigger issue.

If your speakers have a minimal impedance of 1.6 ohms, then that is a giant red flag. That means that likely that the impedance drops below the DC resistance. If that is so, that is one of the worst design errors a designer can commit. It means to crossover is in resonance. Disgraceful poor design in speakers is rampant. That issue is a massive amp buster as well.
