I have yet to see any evidence (anecdotal or objective bench test) that the limp mode is fixed. The firmware change log ambiguously says "Improved Amplifier Power supply sequence" but only Onkyo knows exactly what was addressed.
Wondering myself. Hoping for an answer on both the 50 and 30.
That's not the limp mode that Amir experienced in his bench tests. What you are showing from the manual is a genuine protection mode!
The RZ30 seems to potentially be the first of the next generation, rather than the last of the previous?
Which still begs the question, what is the "protection" mode referred to on the web interface status screen (which has possible status of Off or On) - full shut down protection certainly isn't it, as it would bar access to the web interface!
It could be that and overlooked, but I'm guessing the 4 ohm mode is triggered via current sensing or heat sensing should the sensor(s) see pre-programmed condidions. I would imagine they have done something for the bench testing, but 4 ohm's is definitely forced at volume below -29dB and forced up to 6ohm at -22 dB when I was playing with some basic PCM streaming. You can hear it click provided you have something streaming, or it can / has sensed audio. Powered zone 2 / 3 still forces it down to 4 ohm, and I never re-tested bi-amping, and based on what I have seen, because it doesn't filter the low end to the main output sockets (fronts) like crossover mode on say my 5010 for example, also will probably keep it in 4 ohm mode. I'll try that further down the line. I think the location of the heat sensor is the reason for this, however if it is used without these variables, as a single zone Home cinema receiver as per main customer base, it will keep in 6ohm mode until any of said conditions are met. It must have some degree of audio sensing like the earlier models too. I still recon it would drop back if you saturate it at the clipping point with a 4ohm load too. I don't have dummy loads to test this.
More like the cheapest RZ finally made its debut.
Look at Page 150.
I posted that above and response was that is not protection mode, unless I'm missing something.
I think there's a lot of confusion around what Amir calls "limp mode" and what the manual describes as "protection mode". The 2021 models appear to suffer from Limp Mode. The newer models from 2023 on, based on testing from Gene and Amir, do not appear to have Limp Mode anymore. It'd be interesting to see if Limp Mode still exists in the 2021 models post firmware update, but it would require a test bench to find out.

RZ70 and 30 do not have Limp Mode. 7100 likely does have Limp Mode.
I disagree. There is a $900 stereo receiver out there that does not have Limp Mode.
Will you at least agree we don’t have any RZ30 bench tests, let alone pro reviews other than the Andrew Robinson video?
Agreed. But I will also point out that no 2023+ released product from PAC exhibits the Limp Mode described in Amir's reviews of older products.
So again, the remaining question is what the firmware update does/doesn't do to protection mode on existing RZ50s. One could save $100s if happy with one sub, no pre-outs and still get Dirac.
