PRX Connect 4+

I am able to use the app as intended with my old iPad Gen3 but it simply will not find the PRX speakers using my iPad Gen6 running iOS 13.3.1. For all the hype of the app as a current selling feature of the PRX line I feel a little attention and upgrading to the app is in order.

No, it won't work on your iPhone, for now.
Luckily I had a first generation iPad.
Everything seems to work the way it should. It did take me a little while to figure out and I'm still learning the effects as I type.
Keep your gain low when learning the app, I can see how you could blow your speakers like another review said.

I got the JBL PRX800 series speakers and subwoofers after a few months of research. One of the selling points was that I'd be able to use this app to EQ the system. I had an older Behringer system that got the job done but did not look good and the system would peak all the time if used for a big room. I've heard about JBL and was excited to get them. I got 2 15 inch PAs and 2 18 inch subs. Initially the system was not as loud as you'd expect for something you just paid over $4000 for. I'm used to only turning the gain on speakers to about 12 o'clock position (straight up) and adjusting the volume from my mixer. Well for these I had to turn to almost the 3 o'clock position on the PAs and subs to get a similar volume that I'm used to with my old system. I finally decided to download the app and give it a try. I'm a tech guy so stuff like this is easy. One of the speakers took forever to connect. I had to finally just start over to get it to work. Once I got it connected I thought you'd be able to adjust the sound with a click of a button to get some dramatic sound difference. Well that wasn't the case. Unless you know a lot about digital EQ systems it may be difficult other that just moving the graphs to make it louder. One good thing was that instead of just guessing I was able to get an exact number that I was adjusting the db to. It was cool to feel like I was doing something but at the end I wasn't doing much of anything but just messing with some levels that did not make all that big of a difference, until... out of nowhere there was a deafening screaming noise coming from the speakers. I shut off the main power and made sure the speakers volume was ok and saw that the levels on the graph were super high for no reason so I press the flat button then turned it on again to the same result. I even took the XLR cable out and it was still doing it. Not sure what happened but now I think 2 of my speakers (1 PA 1 sub) are about to go out as the volume on them is drastically lower and sounds nowhere near as good as the other 2. App may be useful to some but it damaged $2000 of equipment. Highly disappointed right now. Have to wait til Monday to talk to JBL to see about doing a warranty claim.
