ART Announces New Tube MP/C Project Series

December 2011

Applied Research and Technology, a division of Yorkville Sound, announces the newest addition to ART’s Project Series, The Tube MP/C , an tube preamp and optical compressor.

The Tube MP/C (PreAmplifier/Compressor) is a multi-purpose tool for audio engineering and recording. Enclosed in a table-top chassis are two independent circuits featuring a tube-based analog preamplifier and a VCA-less compressor with optical gain reduction control.

Used as a mic/line preamp or as a DI (direct) box, the Tube MP/C is designed to work seamlessly with any recording, sound-reinforcement, or electronic instrument setup. A R T’s Tube MP/C circuitry is a hybrid design utilizing the latest, most advanced, solid-state and tube technology.

The Tube MP/C maintains exceptional signal integrity and extremely low noise. A tube based opto-compressor circuit follows the tube preamp. While the preamp is always active, the compressor may be bypassed. The preamplifier’s active balanced solid-state input provides extremely low noise and excellent CMRR. The 1/4″ input has a high impedance, which prevents the loading of any device connected to it and makes the Tube MP/C perfect for DI or line level applications, and a transformer isolated XLR output allows for both the XLR and ¼” outputs to be used at once. The compression circuit features a VCA-less design and utilizes optical electronics (Vactrol) coupled with a 12AX7a vacuum tube gain stage for superior musical performance.

The compressor is soft knee by design. Although it is capable of providing a thoroughly “squashed” signal in “Limit” mode, it was designed to excel in areas where transparent and musical dynamics control is desired. The beauty of the optical/tube design is its ability to apply heavy amounts of compression without pumping and breathing like VCA-based compressors.

US retail pricing for the ART TubeMP/C™ , which includes a three-year warranty, is $129. The model is scheduled to begin shipping in April, 2012.
