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, 2U recording package.

The TUBE-TECH 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.
