It's line level and I inserted it into the chain between my preamp and my amps. I use all XLR balanced cables anyway so it was easy. I have been using the older PA + for years as a sub xover but that was on a second output. This time I put the 360 in between the C1000 and the 501's so it could work on the EQ to my mains as well as the sub. I've never had better sub integration than I have now and it found a lot of peaks and valleys to correct in my (untreated) room. I am going to run through the auto eq again tonight as I realize I didn't put the mic in the correct measurement positions according to their instructions.
I had done this with the PA + a decade ago and I could just "hear" it in the chain. Now (when bypassed) with the 360 I cannot. I believe the PA+ was 24/44 and the 360 is 24/96. It's silent, and transparent - and the iPad app is cool as hell! I love being able to play with the sub crossover slopes, parametric and graphic eq slopes, etc right from my couch. It's 1/10 the cost of the McIntosh MEN220 that I always wanted to play with, and that had no remote interface.
This appears to be a more affordable version of what I had hoped the new DSpeaker X4 ended up as. I am seriously interested but cautious. Glad you are liking it. There was a thread over on ASR about it. But I don’t venture there much these days.
It's definitely Pro gear (+4 db) but it seems to have no issue with my consumer (-10db) gear. It never makes any noises whatsoever (pops, clicks, hums) and it goes into a protective mute mode whenever you are in the auto tuning wizards. I was nervous about anything directly connected to 500 watt amps, but it has behaved like a champ.
For half the cost, the PA2 looks like a good bet too if you don't want direct digital in. I almost bought one and then this 360 popped up on CL. So many pro sound guys are dumping their rigs now because covid just killed the live sound market. There are tons of both units available now both online and on CL.
This would work for me as I use one of my line outs to feed pro bump boxes for my Benchmark studio meters. A ridiculous little luxury for what is essentially bouncing meters. This would at least render that setup functional. Last question at the moment, does it have bypass capability?
I guess that depends on your definition of "bypass". All of the filters can be disabled one by one in the app or the UI on the front panel. But if you're looking for something like a relay "click' for a total analog bypass of the DA/AD I am not sure if that's possible.
