iD2254 module is inspired by a famous British design. Gain control element of this compressor is a diode bridge. Diodes change resistance depending on the amount of current flowing through a diode. This allows automatic gain control of the audio level.
The iD2254 compressor features three transformers in an audio chain. One more transformer is used in a limiter section. Compressor output stage works in class-A which, together with other transformers, give a very prominent and unique texture to the sound.
