    Product Description

    For microphones, acoustic guitar, warming up a direct input to a mixer from a bass guitar, keyboard, etc., there is no sweeter sound than a tube preamp. In response to increasing demand for affordable tube mic preamplification, ART offers the Tube MP with the features that make it as powerful as units that cost 5 to 10 times more. Features include a 12AX7 tube, +48v phantom power, a phase reversal switch, 1/4" & XLR input/output, input control with two ranges of gain (+26dB to +60dB and +6dB to +40dB), and a +20dB gain boost for mics (or use it as a pad for line level signals). A peak LED allows you to precisely monitor clipping and an output control is included for trimming back to unity gain.

    The ART Tube MP is the world's most popular external tube microphone preamp. Whether you're working with a four-track, hard-disk, or digital multitrack recorder, 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 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.
