Tube MP - The Original
The Tube MP is the world’s most popular external tube microphone preamp. Whether you’re working with a digital, computer or analog recording system, the Tube MP’s TEC award nominated design will allow you to obtain professional recording studio results at a fraction of the cost of comparable equipment. The hybrid design of the Tube MP allows it to add warmth and fatness to a signal while maintaining exceptionally low-noise and high quality. While its primary application is to be used with a microphone, the Tube MP is an exceptional direct box - impedance matching, amplifying and improving the sound of any instrument plugged into it.
The usage of external mic/line preamps has become increasingly popular over the past several years. The Tube MP offers superior performance and sound quality to the “on-board” preamps found in today’s low-cost mixers and multi-trackers. It’s sound has been consistently favored over other products costing upwards to ten-times its price. Professional quality sound combined with professional features like: a hand-selected 12AX7a tube, phantom power and phase reverse are what have made the Tube MP a staple in thousands of studios worldwide. For a minimal investment, a Tube MP can provide the single largest improvement to the sound of your studio.

Tube MP - STUDIO V3
The Tube MP Studio V3 delivers warmth and fatness to any audio source while maintaining an exceptionally low-noise signal path. While its primary function is as a microphone preamp with +48V phantom power, variable gain and phase reverse switching, the Tube MP is also an exceptionally versatile tube driven direct box for any instrument source.
The Tube MP Studio V3 uses ART’s proven V3™ (Variable Valve Voicing) Technology to instantly contour the tone to any source. V3™ presets were created and fine-tuned by some of the industry's top studio and live-sound engineers and allow instant access to a multitude of preamp settings designed for guitars (electric and acoustic), keyboards, bass guitars, drums, vocals and more. Additionally, the Tube MP Studio V3 employs OPL™ (Output Protection Limiting) technology to protect the next component in your signal path from clipping and overloads.
The Tube MP Studio V3 offers exceptional sound quality and superior performance to that typically found in “on-board” preamps found in today’s low-cost mixers, multi-track recorders and audio cards making it an ideal tone-shaping tool for any application.

Tube MP - Project Series - USB
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 and added USB connectivity.
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/ME/2000/XP/Vista, as well as Mac OS 9.1 or newer.
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.
