OVERVIEW

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
  • Variable Input Impedance For Flexible Microphone Voicing (150 Ohms To 2400 Ohms)
  • Selectable Plate Voltage
  • Large VU Meters
  • Backlit Function Switches
  • Discrete Class-A Input Microphone Preamplifier

A considerable numbe or ART preamps suffer from poor shielding in the power transformer which causes an acute buzzing. Our studio bought four of the devices and two of them suffered from this problem. ART and Thom Davis refused to honor the 3year warrantee. This company and the people in it build cheap, poorly conceived rubbish. Make your own mind up about ART but we will never deal with them again

    Pros

    • Professional Functions
    • Versatile
    • Warm Sound

    Cons

    • Attenuated Frequency Response
    • Only one tube per channel

    Best Uses

    • Acoustic DI
    • Vocal Ribbon Mic

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

    My favorite use is acoustic guitar DI. This pre adds a layer of complexity in the mids not generally heard from solid state pre's. Big, warm and almost punchy, especially good for finger picking and light strumming. Pops the acoustic forward in the mix. Not ideal for background acoustic tracks (better to use a solid state pre in that application). 2nd fav is vocals with a ribbon mic (in my case the AEA N22). Sounds sweet, intimate and vintagey. Definitely will find its way into my lead tracks. Fav settings are high plate voltage with impedance at 300 ohms (9 o'clock), +20 dB switch in and gain between 10 o'clock and 4 o'clock. Be warned, though, high voltage with high gain setting can burn out tubes fast. I replaced the stock China 12ax7's with Ruby tubes and it sweetened the sound considerably. JJ's or Tungsol's would also be good choices on a budget. But here's my complaint. Only 1 tube per channel. Any decent guitarist or tube pre enthusiast knows you need 2 or more tubes in a pre for it to sound best. Heck, the squeaky clean 1960's Marshalls had 3 tubes in the preamp. 3! Come on, ART. You can add MORE. It would sound richer. But they get a lot of sound out of 1 so I digress. Also, there is noticeable attenuation at the top and bottom of the frequency spectrum. Not sure if that's a side effect of 12ax7's or designed to reduce the noise floor. 12ax7's are noisy suckers for sure. All in all, it's a nice dual pre for the price and I am happy with it. :-)

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

      Very pleased with this device. Great value (i.e. - price, feature rich, great quality). This preamp can be used for a variety of applications and recording setups. It has some features that high-end preamps include. Keep in mind, this preamp is definitely low-end at all. In my perception and opinion, it is situated in the upper-middle category. As mentioned above, the price is very attractive for what you get.

      At the time of this review, I am been using it for approximately 2+ weeks. Stellar results. The tubes that ship with it are Chinese (which sound fine for what I have used this device on thus far). Perhaps in the future, it would be interesting to see what other variations of the 12xx7A family of preamp tubes sound like as well as some other tube manufacturers.

      Overall, without having to change anything, I have been very pleased with the results right-out-of-the box.

        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..

                  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.
