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.
