Tube Tech MEC-1A Tube Recording Channel and DI

The MEC-1A encompasses the all tube based designs of the MP 1A Microphone Preamplifier, EQ 1A Equalizer and CL 1B Compressor in a powerful, two-unit recording package – designed and hand crafted to deliver the warmth of vintage quality recordings with unrivaled accuracy, purity and realism

The MEC-1A Recording Channel is a one channel recording unit, featuring a microphone preamplifier equalizer and compressor. At the heart of the shelving and bell filters you will find a tube operational amplifier.

The MEC-1A is all tube based except for the power supply. Input and Output have fully floating transformers. All DC voltages are stabilized, except the anode voltage for the output stage.
