DBX DriveRack PA 2 x 6 PA Management Processor with Display & US. W/ 3 XLR Cables.

I've purchased two of these to put in my main on-stage signal distribution rack, to replace a pair of the original DriveRack PAs, and a pair of DBX AFS224 feedback eliminators.The main reason for the upgrade, other than saving 2U of rack space and ten pounds of weight by getting rid of the AFS224s, was to gain wireless IPad control over the feedback elimination function during sound checks, and more convenience overall when tuning the crossovers, managing presets, etc.The good news is that the signal processing in these units is great, and the IPad and PC "PA2 Control Apps" are very good, and pretty easy to use. I don't use any of the Wizard functions, and as I design and build my own FOH speakers, so the factory presets are not all that helpful, other than serving as starting points for basic I/O configuration.For tuning, I invoke everything except the Automatic Feedback Suppression (AFS) manually, and do my loudspeaker measurement using a third-party FFT-based analyzer. So for me, the IPad app's crossover tuning pages got a strong workout, and I love the app. I found the crossover filter & slope choices, in combination with the generous 8 band PEQ, and fine-grained driver delay settings, plus polarity control (all on each crossover output!) to be enough to implement a complex tri-amped system that measures and sounds great.I've owned over a dozen analog multi-way crossovers over the years, and a couple of digital ones, including the original DriveRack PA, and I've been designing and building high performance multi-way PA rigs since the 1980s. Compared to anything I've owned before, the convenience, compactness, and sound quality of the PA2 as a crossover/EQ/limiter device for a stereo PA or studio monitor controller is just mind-boggling.So now for the possibly bad news. I run my FOH system in stereo, and one of the two units drives both channels in a stereo configuration. No problem there, the PA2 is doing everything I want it to.However, at a typical gig I run two mono monitor mixes, plus two stereo IEM mixes. One of the mono mixes is for side-fills, and one for floor wedges.So the second PA2 I purchased is set up in dual-mono mode, and is processing the sidefill and wedge mixes.This second application, which is inherently a 'dual mono' situation, is where the PA2 falls down. Although you can set it up with 'Dual Mono' GEQ, this ONLY applies to the GEQ, and not, as far as I can tell, anything else. The crossovers are not independent... so if you are hoping to bi-amp a pair of monitors, they better both need the same settings. This limitation I was aware of and doesn't matter to me; that's a feature that DBX has always held back for the more expensive DriveRack models. What I *didn't* know, and is worse than the original PA, is that neither the Auto-EQ or the input-side parametric EQ are independently accessible for the L&R channels.Worse, the AFS doesn't appear to be dual-mono, either, so the main thing I'd been planning to use this for (remote-controlled AFS for my monitor mixes) is pretty crippled. If you have independent monitor mixes going to individual monitor speakers placed at different distances to the mics, the feedback modes are going to occur at different frequencies. It isn't the end of the world, but it is unnecessarily damaging to the two mixes' sound quality to apply a 'greatest common denominator' of the required filter notches to both of them. This is a step backwards from my outboard AFS224 units, which are truly dual-mono if you want them to be.Note that with some fiddling (and the right cabling), in a 2x2 full-range application like mine, you can work around the lack of independent parametric L&R EQ issue by using the *output* parametric EQs of, say, the Mid and High crossover outputs, and connect your 'left' channel output to the Left Mid out, and the Right channel to the Right Mid output. It can be confusing to remember what's what when you're using the PA2 IPad app, but it does work... but doesn't help with the AFS situation.My overall conclusion is that PA2 is extremely useful when used within its intended applications. Although it is frustrating to know/suspect that these limitations are driven by marketing & product positioning, rather than of the technology, I keep reminding myself how incredibly affordable the product is... and that the Venu360 is out there if I need it.

Excelente producto, pero el único detalle desfavorable es que no pose un botón de prendido y apagado!

Muy buen producto

Did not like that I had to look on the Internet for the Manual

What an amazing unit!!!

Excelente

Eselente

Versital expandabe a lot of bang for the buck great buy for 308$
