Rochester, NY – Applied Research and

Technology (ART) is proud to announce the

new Tube MP Project Series.

The Tube MP Project Series is a professional

quality audio interface that lets you connect

microphone, instrument, and line level signals

to audio inputs to digital audio workstations

as well as standard analog devices.

We took our legendary Tube MP series and

updated every aspect of the design, inside and

out, while still maintaining a compact, reliable,

cost effective product, and added a USB output.

From the new all-aluminum stackable chassis to

the precision LED level metering circuitry, we

have improved virtually every aspect of our

already successful Tube MP series.

The new ultra low noise discrete microphone

preamp front end has an extremely flat and wide

frequency response and handles a wide range of

input signal levels with a minimum of coloration.

This gives you a very clean and neutral sound

with a wide variety of signal sources. The high

impedance 1/4” instrument inputs optimized

for guitar pickups allowing every nuance to be

heard. We use a high quality 12AX7A tube

inside to add warmth to musical dynamics and

the power supply is external to keep AC line

noise and hum back at the wall.

The input Gain control and switch help you to

maximize your input dynamic range as well as

control how hard you are driving the tube. Input

impedance is switch selectable to optimize your

microphone’s response right on the front end.

These two features are a must when trying to get

the most out of a vintage ribbon or studio grade

microphone. The switch selectable high-pass filter

removes very low frequency rumble and wind

noise before it has a chance to overload your

inputs. The Bessel filter design is set at a low

40Hz to preserve bass tonality and time domain

response and it is very effective when tracking

or interfacing to your computer based audio

workstation. Phantom power is available for the

XLR input and is a clean +48 Volts DC from a

low noise internal supply that is current limited

to prevent damage to your sensitive microphones.

A FET Limiter with fast attack and musical release

times limits the maximum audio output level to

prevent overloading succeeding equipment while

still maintaining a clear uncompressed sound. This

allows you to maximize the dynamic range of

your signal before converting to digital. A Phase

Invert switch allows you to switch signal polarity

right at the source. This feature is

especially handy when you are mixing the signal

output with other channels in a mix. The Output

control comes after the Tube and Limiter and is

used to match the output level to a wide variety

of systems. Following it is a new output section

that provides high output signal drive capability

to both outputs.

USB (Universal Serial Bus) is a common hardware

interface used for quick and easy connection

of peripherals like the ART USB TUBE MP. The

TUBE MP features a single Type B USB peripheral

connector on the rear panel for outputting audio

over USB to your computer. One of the nice

features of USB is its Hot Swapping capability,

allowing the Tube MP to be connected and

disconnected without turning your computer

off. The ART USB TUBE MP is fully USB 1.1

compliant, operating under Windows 98SE

or newer, and Mac OS 9.1 or newer.
