OVERVIEW

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.


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

I ordered a restock, tried & returned it, basically due to the following: to get decent levels I had to max everything, then some noise was audible. I may have received a sub-par unit? All I know is I own a Pro Channel (previous version) , which I would suggest over this. If you absolutely need dual channels in one unit, there are better options, but you will pay more.

    Comments about ART ProMPA II - 2-Channel Tube Mic Preamp:

    Had to return first unit...analog meters not working...stuff happens. MF set up the return with no problem...as always.
    Second unit arrived and was in good order. I already had two TUNG-SOL 12AX7 tubes and made the replacement. Is it an improvement? I don't know but I did it because others say it is worth it and I can afford the cost.
    This preamp smoothed out everything I put in it. I was hoping for a string bass improvement and it was there. This preamp is a nice upgrade and would buy again.

        Purchased the Pro MPA to use on top of the Pro VLA and the combination is perfect. Clear crisp vocal sounds as a mic preamp. Great buy for the money.

          Comments about ART ProMPA II - 2-Channel Tube Mic Preamp:

          I bought this unit to improve acoustic guitar and piano recordings. I've only worked on a couple of demos with it so far but am very happy. The acoustic guitar especially has a much more vibrant, warm sound with plenty of level. I'm just using an Audio Technica 20-20 condenser mic plugged straight into one side of the PROMPA II - 2-CHANNEL TUBE MIC PREAMP and then into my Presonus Firetube interface. I'm using Cubase 5 software. Everything is the same as what I used on my last two CDs except for the addition of this unit and it sounds so much better. By the by, I'm using a Taylor acoustic and am surprised at how full and warm the sound is.

            Comments about ART ProMPA II - 2-Channel Tube Mic Preamp:

            IF you have a mixer, then you KNOW what your preamps sound like on your mixer. Do you want to bump up your game? This preamp will change everything. I run this through a mic pre on my mixing board, with the gain on that board mic pre at 0db gain. I use the gain on this unit, put the settings the way they sound good to me and WOW. since there are 2 tubes in this unit, I changed 1 tube in channel 1 for a Mullard 12ax7, left the stock tube in channel 2 to compare the two tubes. You will have to make your own judgement on what you want, but, I can tell you, this unit is amazing. I can't believe how much an external preamp can change the sound of a microphone...amazing...Bottom line, I can run this preamp through my board and use the processing on the board along with this preamp...I am amazed...what a difference in sound..

                  Comments about ART ProMPA II - 2-Channel Tube Mic Preamp:

                  I bought the MPA for use as a preamp in my basement recording studio. This is my first external preamp so I don't have a lot to compare it to except the inboard preamps in my mixers. I find it quiet, easy to use and easy to get the sound I want for vocals, guitars and bass. I was hoping I wouldn't get lost in all the knobs, and I haven't had an issue at all. I pair this up with an ART VLA compressor and get some really deep, warm, natural sounding vocals.

                  I looked at a lot of reviews and I feel like this was a good value.

                  Comments about ART ProMPA II - 2-Channel Tube Mic Preamp:

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

                  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!
