Art Pro Mpa Ii Studio 2-Channel Tube Preamp


Hi this is Ryan with front-end audio. And today, I want to talk to you about the AR, T, Pro, MPA - it's a dual channel tube mic free. So actually a very great valued unit that has a ton of features. And if we look over the front panel here, we can actually see what this thing has to offer looking at the face of the unit. You can tell it's a two rack space unit. So it will need a little extra room if taken consideration when you're looking into this. You have your power switch right here for cutting on and.

Off the unit you have your gain stage here for your mic level and instrument level input, and it's, not DE tinted, but it does have a clicking feel to it. So you can make reference of mental reference or actually just write it down. How many clicks up and down you were on when you were setting up it's, a nice recall feature here you have your impedance, which you can adjust from a lower impedance to higher impedance. And of course, the more you crank up the impedance, the more tames that high-end. So if.

You really need to work on maybe smoothing out the high end of a specific instrument or vocalist. That is a great feature. One thing to note is that this impedance does not infect the instrument input at all right here. You have your master level output. And all of these of course, or have that clicking fill for great recall. And right here, you have your low cut filter that you know, you can get some unnecessary Rumble or kind of tame that low-end, depending on if that the instrument needs or not and. It gives you a 7.5 Hertz to 200 hurt frequency response of where you can star that roll-off right next to that.

You have your high z instrument input, which is great for acoustic guitars, running direct guitars, or even a bass guitar on this side right here. You have your VU meter for each individual channel. And you have a trim here. So you can run your test tones through it and calibrate your VU meter for more accuracy below the VU meter.

You have your 20 DB gain. What this does are, it adds an. Additional 20 DB of gain to the gain stage of the mic pre. So I kind of look at it as it comes with a 20, DB pad, already engaged. So when your said doing drum, overheads, you don't need to worry about that you got plenty of gain here. But if you need a little extra gain say on a coup stick guitar or maybe a vocalist, you can engage in extra 20 Dbs that will give you that extra volume boost that you would need to get a real good.

Take next of that. You have your phantom power. So when engaged, of course, You can power any condenser microphone next to that. You have your high voltage plate. And what this does are it boosts, the voltage going to the tubes to get a little extra saturation going. It does take about 15-20 seconds for it to ramp up or cool down.

So you want to make sure that you if you're engaging this for, you know, adding a little extra some little extra body to say, an acoustic guitar, or something like that you give it time to warm up. And when disengaged give it time to cool down next to. That you have your phase invert, which is pretty self-explanatory if you need to invert the phase of a microphone next that you have your mid-side. Now, what this does are it aligns the output of the unit so that you can actually do mid-side stereo recording. So if you have said you're doing drum, overheads or acoustic guitar, and you have your main mic pointing down in an OFNI or cardioid.

And then you have your 90 degree, off-center microphone and figure-of-eight. You engage that, and it will make sure. That the output of this is aligned correctly to get you that that appropriate mid side function, right above this button. You have your LED meters segmented. And you know, has your green for good level, your yellow for getting a little hot and your ready for clipping. This is a great visual kind of representation of your meters. So if you're a little ways away from the unit, and you can't quite make out the VU meters, you have your LED meters for reference on channel.

Two of the unit you'll. Notice, the. Controls are virtually the same. The only difference here is your stereo button.

What this does are when engaged if you're recording a stereo guitar or maybe drum overheads, or something like that you would want to stereo signal on once engaged the output control of channel 1, then controls the output of channel 2. So you don't have to worry about any adjustments here, looking at the back of the unit. So very simplistic setup, you have your XLR input, your XLR output and a quarter inch output, best. Thing about this all balanced even the quarter-inch output next to that, you have a +4 negative. 10 Io level control. This is perfect. So if you have, you know, a home studio set up and most of your products are going to be running at negative 10, you know, you can engage it to be compatible, or if you're in a project studio.

And most of your stuff is professional, which is going to be running at plus 4 now it's compatible. And of course, right here, you have your IEC power supply, a cable hookup with your. Fuse right here that will of course, blow first to a project your unit from getting fried. If you have a spike or anything like that. These units are also configurable for European voltage. So international customers are going to be taken care of overall. What I have found this to be very useful on is a just a variety of things it's, a great versatile, pre, I, primarily like to use it on drum.

Overheads get a nice pair of condenser microphones spaced pair or mid-side. And it just does a great job of adding. A little a two-body to that, uh to that signal to kind of thicken up the overall sound of the drum set, but it's a very clean signal at the same time.

I also find it very useful when recording stereo acoustic guitars, it's always a big issue. You know, getting that right, acoustic sound. So whether you're doing the mid I tore a space pair or, however, you're going to be doing your setup. You got a great solution here, and it won't break the bank. The last thing I really love this on is this direct. Input I love running a bass guitar through this I don't to do bass. Amps I, always do my bass direct in the studio that right.

There is a great feature, because it gives me a little of thickness with that tube, especially engaging the high voltage plate. The other thing that I really like about it is if I want to get a little edge, I can crank up the input, but leave the output down and start to break up and get a little of distortion out of that tube and really kind of just add a little extra. Dimension to the little extra dirt to the signal, so it's, a great value in that fact, highly versatile will not break the bank. So home studio guys, definitely got to scoop this up would find a great home and be very useful in a project studio, all in all the whole MPA line. The entire tube line from art is just a great value for its price ranges, it's, an extremely hard unit to beat, so I, highly recommend. You give this look and for more information on the art Pro MPA - and for all your pro.
