Model 285e

FREQUENCY SHIFTER / BALANCED MODULATOR

This module is the e series reincarnation of the 285. A long time coming, but well worth the wait.

The top section performs frequency shifting; up and down outputs are simultaneously available. The reference frequency can be externally applied or internally generated; the latter can be voltage controlled and f.m. modulated.

The bottom section is independent, and functions as a balanced modulator of applied signals. The degree of modulation is voltage controlled, and the reference frequency can be internally generated or externally applied, as in the frequency shifter. A separate output is dedicated to classic ring modulation, a subset of balanced modulation.

All settings of the 285e can be stored and retrieved with the 225e or the 206e preset manager.
