      I used this as a preamp for my turntable to add tube warmth to my system,- amazing tube sound enhancement - this preamp can be used at line level or Mic level input with variable input impedance and gain. Extremely versatile ... I am swapping out the stock 12ax7's for large plate Sovtek tubes eventually - but I don't hear any distortion or tube harmonics as delivered by the manufacturer with the stock tubes. Extremely low noise level.

      No real complaints here ... It does require a bit of patients to get the right gain and impedance for the input signal - trial and error worked for me.

      Worth every penny ... Great unit - I highly recommend it.

      I love ART products. I possess two TPS II and a PRO VLA II. I wanted to try the Pro MPA II which is more precise, and has no presets that alter the sound.
      The one I bought here wasn't working fine. The VU Meters were stuck and the preamps noisy. One of them wouldn't even amplify the sound...
      It's the second time I have a brand new art product not working.

      I recommend it though, because once it works, it's worth the price.

        Nice and quiet with quality sound and plenty of output (three stars). I might have given it Five stars, but the VU meters don't move even when I'm pegging the meters on my mixer. I sent it back to B&H three days ago and they already have a new one on the way.

        Comments about ART PRO MPA II - Microphone Preamplifier:

        Although I have a tube mic and several software tube emulations in my project studio, I thought a real tube preamp might be a great addition. And having variable input impedance like the Pro MPA II provides would be very beneficial with my dynamic and ribbon mics. I record small sessions, usually one or two musicians on acoustic instruments (and some electric guitars/bass) so both the mic level inputs and the instrument inputs will be employed at various times. I started out making some technical tests - first noise measurements. Using a 150 Ohm XLR terminator on the mic inputs and with all gains at max, I found the EIN lower than the -129 dBu spec, very quiet. And the two channels matched within a couple tenths of a dB. At any gain I tested the output noise level never exceeded -80 dBu. Next I measured gain and gain matching between channels using a line input. Even intermediate settings of gain on the detented dials tracked within 0.5 dB. Very impressive performance. I analyzed the distortion characteristics using both the low and high plate voltages, and a spectrum analyzer, as well as listening to the 'fattening' of the test signals. Again, the two channels performed closely at the same drive and gain settings. And the overdrive effect was very controllable, slowly increasing with level at low plate voltage, and popping up suddenly at maximum drive with the high plate voltage. In fact, the high plate voltage mode can provide very clean sound if you desire it -- just keep the tube drive level at least 8 dB below the 'red' zone of the Tube Warmth meter. Very versatile preamp.I also ran tests with a ribbon mic and a condenser mic., and found I could significantly change the tone of the ribbon by changing input impedance, and could easily push the tube drive level with either mic hard enough to get a good 'tube' sound. Overall, I am very impressed with what Applied Research and Technology has delivered with the Pro MPA II.

        Comments about ART PRO MPA II - Microphone Preamplifier:

        I use this with a pair of condenser mics--one on vocals, one on accoustic guitar. There is a nice warmth and plenty of punch at the output, which I send to a dbx 265 compressor. Most of the controls are pretty intuitive and the large VU meters with associated peak level LEDs give you an easily readable reference--along with a great retro look. I have not been able to determine exactly what the impedence matching control does. I understand the purpose of impedence matching, but cannot discern any difference in the sound no matter where I set it. Maybe I need more practice, or better ears.
        I would definitely recommend this anyone looking for a good low cost mic pre with some really advanced features and great looks.

          I purchased this in a recording package I built to be a rack mount portable recording studio system. I added this to a DBZ 266XS Compressor/Gate and a SS-CDR200 recording unit. The true test came when recording a local symphony when I heard the sound produced and recorded by these units working together. Smooth, clear, unmolested sounds were the mark of the day. The orchestra members and the director were very impressed. ..and it was easy to set up for this impressive recording!

            Comments about ART PRO MPA II - Microphone Preamplifier:

            I work for the communications office in Victoria, Texas. We use the PRO MPAII for the radio programs we produce for four radio stations in town and for a lot of voice over projects for both radio and audio projects for our City-owned television channel.
            The unit is a very high quality mic preamp that has better audio quality than the mixer preamp we were using. The set up is easy and the preamp has lots of gain.
            It does take a bit of learning to get just the right amount of gain, impedance setting and output for each mic. We use both Rode NT1as and Equitek 100S mics with this preamp - both sound great through it. We set the impedance on the actual microphone to start with and experiment from there. We use the "high" tube plate button on, 48 volts on (for our mics) and the plate voltage on high. We use a fair amount of the "tubes" to soften the mics.

              I have 4 ART Stereo preamps in my home studio, and 2 of this specific model. I have a previous model, and the digital version, also. To my ears, they sound great, giving me a pleasing, warm, tube-ish sound. The adjustable plate voltage gives you a lot of flexibility, and can make even SM57 mics sound pretty darn good. With a good condensor mic, they are wonderful. They have enough gain to use with Cascade Fathead ribbon mics. Sound-on-Sound recently did a test of eight different pre-amps, some very expensive ones, and this one did very well in blind tests.

                Comments about ART PRO MPA II - Microphone Preamplifier:

                This was that unique piece of gear which didn't have a lot of features I didn't want, and is really high quality on the main feature I DID want: great sound with just the right amount of creative control. Based on the quality of sound, I can't believe this unit doesn't cost $1,000 or more. My only disappointment was a "fuzzy" sound out of the box with the cheap tubes that came with it. I swapped those out with some Tung-Sols, and the sound was rich, clear, open and detailed, and with the quality that I call REAL (rather than "warm") and not clinical. Also has plenty of gain, more than enough for most mics, and enough for ribbons, with the impedance matching which is also very useful. I look forward to trying the M/S feature. This unit is priced so attractively that I could see myself adding another unit for two more great-sounding channels.One possible frustration for some is that there are three gain stages (plus a level switch on the back), and each has its own purpose and limitation in how you use it. There could be a bit of a learning curve for some, but it is absolutely worth your time to learn what you can do with this! The ability to be creative in shaping the sound at this stage is very rewarding.Also, unlike some other "tube hybrid" designs, the ART PRO MPA II allows you to operate it in "starved plate" mode OR "high plate voltage" mode. And in each mode, you can drive the tubes hard or easy, and decide how you want to shape your sound with this control. For me, this is exciting and attractive. I hear "how did you get that great sound?" It's this preamp!I use this product primarily to record live acoustic music. I think most people look at this as something which sits in a studio, but it does really well in a rack case on location.

It gives a really nice sound to my recordings. I use it for guitars, bass, vocals & more. If you are searching for a cheap preamp, you will like this one. With enough gain, you get a nice warm sound. Great !

                    When I first bought this pre I put it through some testing with the original stock tubes(12ax7). It makes a good preamp but then I switched out the the stock tubes for some new Mullards CV10 4202 millitary grade tubes (post 1980's) it became a great sounding preamp. I like the M/S option, variable impedence and the plate voltage switch. It is a great value at this price.

                      I just bought this pre-amp about 2 months ago and so far have had no issues at all. One of the selling points for me was the variable impedance, it offers amazing flexibility!
                      The ability to to control both how much "tube" sound you want, as well being able to exactly match the mic and then play around it a bit is incredible.

                      I have heard of people switch out the tubes for better one, and I guess depending on your application may be necessary but all in all it gets a great sound out of the box and especially for the price!

                        Sounds great once I changed the tubes. Provides a lot of options, like the Impedance dial, which gives a lot of different tones. I like this unit.

                          I used this as a preamp for my turntable to add tube warmth to my system,- amazing tube sound enhancement - this preamp can be used at line level or Mic level input with variable input impedance and gain. Extremely versatile ... I am swapping out the stock 12ax7's for large plate Sovtek tubes eventually - but I don't hear any distortion or tube harmonics as delivered by the manufacturer with the stock tubes. Extremely low noise level.

                          No real complaints here ... It does require a bit of patients to get the right gain and impedance for the input signal - trial and error worked for me.

                          Worth every penny ... Great unit - I highly recommend it.
