The Model 583E is a 500 series tube preamp with an EQ section that can function independently as two separate modules. Incredible on microphone source, it also features a Hi-Z input for instruments. The 583E features a single channel vacuum tube preamplifier with LaChapell Audios proprietary TrueTube™ technology. TrueTube delivers 250V to the tube, properly powering it so that it operates at its full potential and is not starved for power.
