"Effective but tricky to learn"
This reviewer purchased this item from Same Day Music.
Sound quality is very good. It operates in digital with good converters. Plenty of headroom using +4dbu input setting. I don't even use the -10dbv setting, my experimentation shows +4dbu works for me.
Not just -36db of automatic or manual EQ "cut" to notch out feedback, but filters can also be set manually for up to +36db of BOOST, at any selected frequency, at any width from 1/60 to 10 (insane) octaves. Try THAT with your 31-band EQ! You can use it for tone shaping at the same time as feedback suppression. I like to set 2 filters manually to shape the bottom end on my mains. I set one filter for 27.2hz, 2/60 octave, -33 db, and this totally removes subsonics without affecting anything above 30hz. Then, because my woofers have an F3 at about 44hz, I set another filter at 44.2hz, width at 0.33, gain at +3.5db, and this fills out the bottom end nicely without boosting anything below 30hz. The result is maximum bass without wasted power. I had to use a signal generator of my own to produce test tones to figure all this out, but it was fun! For monitors, I use the same rolloff at 27.2 hz, but more width, 3/60 octave, and it rolls off everything below 50hz. Very useful! This thing also has midi connectivity that I don't even know what to do with... Maybe you do!
Ease of Use:
Once I figured this thing out, I realized it is a very effective unit, especially for the price. But it took hours of experimentation in the basement with PA gear to understand how to apply what is in the user manual, and discover a few other things not really mentioned. It's not really a complicated piece of gear but the manual isn't "dummy clear" in some ways. Take the time to play with it, and you'll figure it out. I don't like the "Auto-Learn" mode to force feedback, because it seems to cause runaway feedback sometimes... maybe I just haven't figured out how to use it right yet. I like to ring it out by cupping my hand over the mic with too much system gain, get it to ring, auto or single-shot filter grabs it right away, then back off the system gain a little and it behaves.
Decent build for the money. The cable jacks aren't nut-anchored to the case, and the knobs & buttons aint "mook-proof", but that's normal at this price point. Just don't abuse it and it works. Fully-balanced inputs & outputs, TRS & XLR. Stereo or dual-mono.
Can't comment here, haven't gone there yet.
For about 160 bucks, totally worth it. I own 4 of them, got the first 3 years ago, and bought more after I got the hang of using them. I put one before each power amp.
The Wow Factor:
Well-engineered and innovative. Good stuff for the money.
This thing will "ring out" your monitors and mains quicker and easier, and more effectively than a graphic EQ ever could, once you get a clear understanding of how it works. Also does other useful things as well.
