The ART Pro MPA III Tube Preamp brings flexible analog tone shaping, real tube character, and modern studio practicality together in a dual-channel design that can seriously elevate the front end of your recording chain.
Whether you're tracking vocals, instruments, bass DI, podcasts, or ribbon mics that benefit from careful impedance matching, this multivoice tube preamp gives you the control to move from warm and harmonically rich to clean and articulate without losing its studio-ready appeal. Built around discrete Class A FET microphone preamps and a selectable 12AT7 tube or solid state voicing path, the ART Pro MPA III is designed for engineers and creators who want more than a one-dimensional preamp. Each channel offers variable input gain, output level, low cut filtering, and microphone impedance control, making it easy to tailor the response to a wide range of microphones and sources. The expanded impedance range is especially useful with dynamic and ribbon microphones, where subtle loading changes can have a meaningful impact on tone, transient response, and overall feel.
Version III
New to version III, the Voice switch allows you to choose between tube warmth and a cleaner solid state path, while the Character switch helps enhance low and high frequencies for added presence and improved vocal intelligibility. With XLR mic inputs, 1/4-inch instrument DI inputs, balanced XLR and 1/4-inch outputs, selectable +4 dBu or -10 dBV operation, analog VU metering, and a universal internal power supply, the ART Pro MPA III is a versatile studio preamp for project studios, home studios, and professional production environments alike.

Loaded With Features And Tweakability
Jul 24th 2015Like many other home studio owners, I was looking for value and quality in a mic preamp that is not boring and lifeless. Enter the ART Pro MPA-II. A true full voltage tube preamp. 150 volts on the tubes produces a tube sound they way it was meant to be. Both input and output controls and great metering of both input and output. Now, the real beauty of this preamp is how it responds to tube changing. No other preamp I've ever used is so sensitive to a tube upgrade. I tried many, many tubes and found the holy grail: NOS JAN Phillips 5751s. Makes the already great sounding Pro MPA II sound world class. On top of that, it has what to my knowledge no other mic preamp has: a continuously variable input impedance control. Turn this control to about 600 and voila! Instant vintage sound. It's the one preamp I use on almost every source (I have several). I'll never part with mine. By far the best product ART have ever made.

Tube Swap and you are in Business
Sep 29th 2014This unit is great and when you switch the voltage on the face of the unit it gets even better. Tons of warm saturation, its a great bass DI. One thing I suggest is to get a NOS Mullard Tube and a NOS Telefunken tube. I did this with my unit and the differences were subtle yet noticeable. I basically had 2 different tones from each channel. Came in handy on different voices with different mic selections.
