The Tube MP/C from ART is a single channel tube preamp with a switchable optical compressor, all housed in a rugged desktop enclosure. Used as a microphone/line preamp or as a DI (direct) box, the unit is designed to work seamlessly with any recording, live sound, or electronic instrument setup. The preamp's active balanced solid-state input delivers extremely low noise and good common mode rejection. The Hi-Z input prevents the loading of connected devices, perfect for DI or line level applications. The preamp's second stage 12AX7a tube runs on a regulated DC voltage providing an additional 20 dB of gain. The compression circuit features a VCA-less design and utilizes optical electronics coupled with a 12AX7a vacuum tube gain stage.
