RED mode is a British classic style preamp (1073) and GREEN is an American vintage style preamp (discrete opamp). Both preamps have unique sonic textures known as a best classical sound preamps. Carnhill transformers are responsible for matching impedance and de/symmetrization circuits. Preamp is loaded with two PADs: IN 20dB PAD and OUT 8dB PAD which allows to saturate both preamp and output transformer.
