285t Frequency Shifter
Specializing in an array of delightfully clangorous timbres, the 285t allows you to frequency shift, ring modulate, and blend between the two to incredible degrees of control. The magic of the 285t is perhaps in the fact that all of these options are available simultaneously, giving you abundant flexibility in constructing patches.
The Frequency Shifter section at the top offers both Sum and Difference outputs—that is, upward and downward frequency shifting. Using the internal oscillator, you can apply up to 1kHz of shifting, but an external Reference input is also available if you'd like to use it. Bipolar CV and linear FM inputs for the Reference oscillator allow you to get even gnarlier if you like.
Ring modulation is created by combining the upward and downward frequency shifter components together. Of course, you can blend Sum and Difference externally to create ring mod timbres, but the Balanced Modulator at the bottom also makes this possible for you, and with a variable blend control to boot. With an applied control voltage, the resulting dynamically morphing timbres can bring depth and richness to any sound source.
The 285t Frequency Shifter is an interesting module for processing audio samples or live voice input via a microphone through the 207t Mixer/Preamplifier module. The "sum" and "difference" outputs from the 285t can then be routed to the 292t Quad Lopass Gate, creating dynamic tone shaping. By further splitting the processed signals into the left and right channels, this setup allows for a rich stereophonic effect.
