Acurus ACT 4 firmware update problem/question to owners

I have tried to find text where it is written that the 20 channels upgrade is free.  Without success.
But , I am shure , I have once read it.
So , confirmation about that from Indy Audio Labs is required.

Let us know , if every things  turn out right for you.

Yep. Spent two days testing, no bugs noticed. Some steps in the menu take time, but that’s expected from a computer-like devise. 
Main problem was to reach Acurus people since I did not receive any response to my email to support@

However, after the contact was established with you help, they were very helpful. 
Update procedure was set up in the most complicated way possible, however there was nothing unusual to the advanced Windows/Linux/Mac user. 😂

It seems like I will also have a chance to test Aragon Iridium monoblocks soon 😉. Those are out of my budget, but I’m very tempted to give them a weekly run with ACT4 at my home.

I am glad your issues  are solved
The 20 channels upgrade kit improves something in the DSP  or 
something else ( I am realy not technical )
It allows you to use the incoming ASPECT  room corrector.
There is a HDMI upgrade availlable also .( 8K  , E arc ) 
Imax Enhance  and DTS X Pro  hardware upgrade is  coming .
I think , they don’t beleive much in Auro 3D format.

Fortunatly , the ACT4 , is upgradebale .  Future inovations will be 
availlable.
