Frequency Shifter Model 285 by Black Corporation & Buchla
The Model 285 reissue combines two sets of functions - a top section with frequency shifting, and an independent lower section for both balanced modulation and classic ring modulation, all under complete voltage control. In addition to an ample supply of dedicated output jacks with multiple functions, you have musical control over all parameters with separate attenuators and the ability to dial in the amount of ring modulation you desire.
Features:
Frequency modulation section with both external signal input and an internal oscillator, plus attenuators for each
Frequency modulation input and attenuation for the frequency shifter section
Balanced modulation output, with both variable output jacks and dedicated classic ring modulation outputs
Difference and sum output jacks
Amplitude knob crossfades between source signal and ring modulated signal
