Been chasing around for some USB to RS485 RJ45 connector today, managed to buy one, then discovered that there does not seem to be a fixed international standard for connecting RS485 on RJ45 so I am trying to figure out which connector goes where while waiting for a reply from the dealer.
Well... I know this is highly unscientific, I do not have access to several actively cooled 8Ohm 1kW resistors.
Changed the soundcard to my daughters Audient iD14 and it is much quieter, will definitely be buying something better soon.
EQ'd the hell out of my dB-Mark HDX28 on some spare outputs and went for it on 2 x 18" free air to load two channels on the same module, I routinely noticed 66Volts near peaks and the amp is not breaking a sweat, the drivers are being driven a little bit past xmax which is over 10mm, IE more than 2cm flapping which is very exciting to look at so I am hesitant to push further.
Still, I am calling this verified and tested at 550Watts per channel because my voltmeter is slow to read, having tried this there is no doubt in my mind that I can get at least 700 very clean Watts per channel in 8 Ohm from this thing but I do not have enough "load" to verify this completely.
Because of issues with figuring out the right pinout for the RJ45 I am unable to test the DSP functionality at this point, have good trust in the dealer as they gave me access to software and some information to get stuff started. It is a very different time zone, so the delay in communication so far has been very reasonable, very quick response so far.

Figured it out!
Pin 1 and 2 on the RJ45 connector, the orange pair if you follow T568B, or the green pair if you follow T568A.
DSP connects just fine now, will play with it tomorrow.
Got liftoff!
Woohoo!

Thanks for posting this.
Does it have 15 band EQ or just 7? The frequency goes down to 10 or 20Hz?

If you want to activate the HP filter the setting starts at 19.7Hz, you do not have to activate it.
Each of the 4 inputs have 31 band EQ, and the outputs have 7 each, so it is possible to have up to 38 per channel if you want to.

hey so..OMB makes most of the OEM amps for all the brands in china
so CVR , ADMARK and SANWAY are OMB inside ?
The OMB amp doesn't look anything like what the other companies are selling.
1 amp module for two channels with OMB vs 1 amp for each channel with other companies

Yes, it does.
Will be using this mainly for my 4 x 18" so FIR is pointless for me, I could have a look at it if there is some interest.
And not entirely certain, but it also says somewhere that it supports over 400V AC, it says 460V in the manual, so on a creatively connected 2 phase 16A I guess it is possible to get 6400W into this thing, will not be trying this myself.
3 of these amps wired in 2 phase on a 3 phase 32A 400V setup could be possible I guess, would get a theoretical 6400/4=1600W peak in 4 Ohm loads.
12*1600W sounds like a good time to me.
Would suggest the PFA20K with a proper power connector instead though, not that big of a difference in cost and much safer.

Hah! Well, the 18"s were flapping about in free air ca 22mm total, around 11mm each way, a bit hesitant to push them further.
I am experiencing violence in my listening position!
Physical assault!
Reached a critical lack of patience with all the issues surrounding CNC stuff not working, rage-built some OB setup today, brute forcing power to the 18"s was so impressive that I decided to try making some quick and dirty OB thingies.

Ridiculously dynamic, and loud. The amp sounds really clean, but it does not like to play low, need to cross a certain threshold of input but then it's really good.
you mean low freq like 30Hz or you mean low level like when you barely make the 1st segment LED to lit.
I am not 100% sure what is the cause, it seems to me that the -80dB threshold is interfering with the input level somehow and it could possibly be a noise gate though I am not sure where I can deactivate it.
When mapping inputs the lowest level of attenuation is -80dB, I set them to 0dB and double clicked to activate the mapping and everything works fine when I feed a certain level to the amplifier. At low levels there is nothing, increasing signal level to a certain point it is easy to hear that there is a certain amount of signal strength required to get steady output.
