Le TubeMP/C est le préampli Mic/Ligne/instrument a tube (12AX7a) permettant d’améliorer le signal en amont d’une table de mixage ou d’un systeme d’enregistrement. Comprenant un compresseur optique et la technologie Vactrol délivrant une compression plus transparente et neutre, il peut être être utilisé également comme DI.
