ART

An affordable high-performance, 2-channel microphone preamp.

The new ART ProMPA II is the next generation in affordable high performance microphone preamp technology. Each microphone input circuit, with selectable 48v phantom power, features variable input impedance which can radically vary the overall performance of any high quality dynamic or ribbon microphone. The ProMPA II can be configured for dual mono or stereo operation with selectable mid/side mic support, summing the adjacent channel, to decode left/right signals.

The ProMPA II can operate at either a low or high plate voltage on the two integrated hand-selected 12AX7 tubes for wider variation of preamp tone and performance. Large back-lit analog VU output meters display input or output levels while multi-colored LED arrays, with average or peak hold, show tube gain.

Housed in a standard 2 rack unit space rack-mountable steel chassis, with CNC routed black anodized aluminum face panel, the ProMPA II is designed to deliver years of reliable operation in the studio, production facility, or on the road for live sound reinforcement.

Features:

Pretty basic features, the same as any basic preamp. Nothing stands out as better or worse than others in this price range.

Quality:

The build quality looked good until I turned a knob and it came off in my hand. I had to return it. Too bad; the rest of the unit appeared solidly built.

Value:

I found the sound to be thin, lacking depth and body. The lows were missing, the gain had to be turned almost all the way up to hear it. And there was no audible "tube quality" to the sound, no warmth, no defiinition.

Overall:

I tried various signals without finding anything that sounded good through it. I was better off sending signals straight to mixer's preamps. So I returned it.

WOW... I just bought one of these Pre-amp units for my Studio. I had read reviews about how great this was, and it lives up to them all. I took the advice of others and changed the stock tubes out right away. I used the (Tung-sol 12ax7) tubes as recommended by other reviews,  and they have proven to be a good choice as well. For Acoustic Guitar Recording you are not going to find a better sound anywhere near this price! Reallly great pre... can't say eoungh about how much I love this unit. it has great warmth and presence and almost no noise at all. Very Quiet and Clean even when cranked. So versitle, so easy to use... Get one for your studio!

So, this preamp boasts it's a tube with digital ADAT and SPDIF outputs.  Well, there's good and bad to this: The Good- it's tube, so it does sound warmer...especially when you play with the impedence knobs.  The digital outs make this a pretty versitile unit.  Quite handy indeed. The Bad- the tubes are extremely cheap.  change them, but don't use grove tubes.  go with maybe tung-sols.  also i suggest 12AT7 vs 12AX7s. Also, the digital outs are ok...when they sync up.  I have to play with mine for a minute just to sync up correctly with my Motu 2408.  It eventually gets there and sounds fine, but it's kinda a hassle.  The analog out sounds really good though.  Overall, this is definitely a fantastic unit for the price.  Maybe not quite high-end studio stuff, but really good for upper end home or low budget studios.
