The top section of the dual-function 285e 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 modulated using FM.

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

All settings of the 285e can be stored and recalled as part of a preset using the 225e or the 206e Preset Manager.
