Compressor / Gate

Tube Tech LCA 2B is a 2-channel Compressor / Limiter lamp. The compressor has six presets attack / release and a manual command. The attack / release limiter is fixed. The LED display is powered by the control amplifier. The audio path is fully symmetrical from input to output. The inputs and outputs are equipped with fully floating transformers. All DC voltages are stabilized except the anode voltage for the output stage.
