Description

Unlock the full potential of your modular synth setup with the Tiptop Audio Buchla 285t Frequency Shifter and Balanced Modulator Eurorack Module. A harmonious blend of Buchla’s timeless design philosophy and Tiptop Audio's avant-garde innovation, this module is perfect for sonic sculptors looking to explore the fringes of sound design.

The Buchla 285t is not just a module—it's a dual powerhouse of modulation magic. With its independent dyadic architecture, it houses both a frequency shifter and a balanced modulator, each with dedicated audio and CV inputs. This allows for unparalleled flexibility and creativity, effectively giving you the functionality of two distinct modules in one compact unit. Whether you're seeking analog stereo widening effects or diving into complex ring and amplitude modulation, the 285t offers a universe of possibilities.

The frequency shifter component can process audio through either its internal oscillator or an external source. It provides both sum and difference outputs to enhance your stereo imaging techniques. Meanwhile, the balanced modulator section allows for intricate modulation effects, transforming your audio input into a carrier signal that's ripe for modulation.

Key Features:

  • Dual-function module with independent frequency shifter and balanced modulator
  • Internal and external oscillator options for frequency shifting
  • Simultaneous sum and difference outputs for stereo processing
  • Comprehensive ring and amplitude modulation capabilities
  • Independent CV and audio I/O for each section
  • Ribbon power cable included
