All-tube mono recording channel with microphone preamplifier equalizer and compressor
The MEC1A is an all-tube mono recording channel, combining the classic TUBE-TECH designs:
MP1A mic preamp, EQ 1A active EQ and CL2A compressor in one powerful, 2U recording package.
The MEC1A delivers true TUBE-TECH sound: Full and warm, yet open and transparent.
MEC1A is a compact and cost-effective solution if you need a superior front end that will deliver top quality recordings, no matter what source you are working with.
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.
