The 323 Discrete Mic / Instrument Preamplifier for 500 Series is powered by an original and proprietary 9-transistor Amplifier and boasts 3 Cinemag Transformers. Switchable inputs of Microphone or Hi-Z instrument (balanced or unbalanced). Only the finest components are utilized in this high end piece. Vintage style metal can transistors are used for the audio signal while modern surface mount semiconductors handle the electrical supply signal (current sources).



The 80 Hz High Pass Filter is great for getting rid of rumble and an indispensible tool.

This unique circuit also adds an extra layer of delicious discrete transistor amplification.
