Amazingly good for pulpit-mic management

At my itinerant church, where the sound system packs into a closet every week, the ART Tube MP/C has substantially improved our quality of life. The super-transparent compressor is proving ideal for our live sound reinforcement needs. We can hear worship leaders and Scripture-readers above the noise of children, but the preacher doesn't hurt our ears when he raises his voice for emphasis. The MP/C powers a Shure lectern mic (which we mount to a mic stand) and outputs to our Fender Passport Pro 150 PA system (using an XLR-to-TRS adaptor; plugging into the XLR input yielded a buzz). I use the compressor in Limit mode, I set the threshold just above the preacher's conversational voice level, and I don't have to ride the volume knob anymore. It's luxurious. When I took it home to track a choral rehearsal recording, I was yet more impressed with how unobtrusive the compressor is—the main impression was that loud passages just didn't hurt my ears coming out of the headphones anymore. Just for fun, I switched it to limit mode and recorded a few lines of a Jason Mraz song, exaggerating the whisper-then-shout technique. The Tube MP/C was unfazed. The absence of an expander/gate or de-esser became apparent with that kind of pushing, but it still sounded quite remarkably polished. Also, it just feels classy. Compared with the ART Tube MP V3, the connections feel more secure, the XLR input locks, and the knobs feel sturdy. Praise the Lord.

everything and more

Simply put, it does everything it says it will. I am using it as a preamp for my bass rig. The tube pre delivers a warm rich tone with that sweet break up when pushed just over the limit. The compressor it's absolutely marvelous. It is so smooth. You actually never really hear it working until you turn it off. The compressor itself is worth the purchase. I absolutely love it and totally recommend this product. I'm sure it will work fabulously for your application as well.

Worked for the Mandolin

It did the job I needed. Provided the boost I needed for the contact mike on my mandolin.

great preamp

guitar, moog, vocals, whatever this thing is running always sounds great. the +48v switch works wonders and the gain sounds way better than my on board mixer's. the compressor sounds great. you cannot run dual inputs (meaning, no XLR and TRS at the same time) but thats probably for the best. for a good smooth setting it helps to follow the instructions provided the first few times, until you know what to look for.
