Two independent circuits featuring a tube-based analog preamplifier and a VCA-less compressor with optical gain reduction control are housed in one, convenient desk-top chassis. 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.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eThe preamplifier's active balanced solid-state input provides extremely low noise and excellent common mode rejection. The -inch high impedance input prevents loading of any connected device making the Tube MP\/C perfect for DI or line level applications.
