Ring Modulator/Frequency Shifter

The Radius is a ring modulator and frequency shifter with pitch tracking and an advanced LFO. It is designed around a novel "eight-quadrant multiplier" algorithm that smoothly transitions from ring modulation to frequency shifting and allows different frequency ratios for the upper and lower tones. Radius puts complex harmonic structures, bell-like tones, metallic textures, frequency shifting, soft tremolo, and bubbly phaser sounds at your fingertips.

A ring modulator multiplies two signal signals together to create new frequencies that are the sum and difference of the input frequencies. One signal is your instrument, and the other is an internal oscillator. The Radius can double the sum or difference frequency ratios and adjust their relative levels, unlocking a spectrum of timbres beyond traditional ring modulation.

Pitch tracking, a push-to-tune footswitch, and picking dynamics make the Radius responsive and predictable on stage. Hold the left footswitch and play a note to tune the carrier oscillator to that note. Pitch tracking maintains the pitch ratio as you play up and down the scale, or tracks by a ratio (or inverse) for more dynamic sounds. An expression pedal can be assigned to any combination of knobs.

The Radius has an advanced LFO with triangle, square, random waveforms and an eight step sequencer, all of which can be envelope triggered. The envelope follower makes it responsive to playing dynamics, and two "X" modulation waveforms create sweeping spectral changes.

Well-spaced controls and stereo input/output make the Radius perfect for sound design, synths, and creative mixing. A full MIDI implementation allows you to sync to MIDI clock, sequence parameter changes, and play the carrier oscillator from a keyboard.

The Radius is a musical ring modulator and frequency shifter that transforms the timbre of your instrument in new ways. With deep features and intuitive control, Radius modernizes classic electronic techniques for the future.

Features:

  • Stereo ring modulator and frequency shifter
  • Continuous mix between ring modulation and frequency shifting
  • Selectable 2X frequency ratios for upper and lower sidebands
  • Frequency shifting with feedback
  • Three carrier frequency ranges (low, high, quantized)
  • Carrier frequency pitch tracking (monophonic, +/- 100%)
  • Push-to-tune carrier oscillator
  • MIDI-playable carrier oscillator
  • Multi-waveform LFO (triangle, square, random, intelligent random, X mod +/-)
  • Step modulator (1-8 steps), programmable via front panel
  • Tap tempo and MIDI clock sync
  • Envelope follower
  • Envelope-triggered LFO (one-shot ramp, pulse, random, step mod)
  • Presets (4 on board, 100 via MIDI)
  • Expression pedal assignable to any combination of knobs
  • Configurable AUX switch (tap, tune, preset, LFO)
  • USB and TRS MIDI
  • Full MIDI implementation
  • 96 kHz sampling rate
  • +8 dBu max. input level (line level friendly)
  • Web editor with preset upload/download
  • User-installable firmware updates (USB)
  • Designed and assembled in USA

Requires a 9V DC 200 mA power supply (not included).

Warranty & Returns

All New products are covered by the manufacturers new warranty. Please check their website for the length of warranty and warranty conditions. If an item you receive is faulty get in touch with us ASAP. Second Hand products come with a 4 week warranty from us. If there is an issue let us know ASAP! This covers normal use and does not cover accidental damage, misuse, wrong power plugged into it, modding, water damage or any other damage caused by mistreatment. Just treat it nice and all will be good!

Shipping

We send A LOT of packages every week so don't worry about the shipping side of things!

We've never lost a thing and your awesome new gear will be packed up really well to avoid any damage in transit.

If your order comes in before 2pm we will ship it same day. Most of the time we pack things up all the way to 4pm so just call if you need it to leave same day after 2pm.

We ship mainly with Australia Post but may use a courier depending on location and size of the package.

Free Post ships with Australia Post standard and expected shipping times are between 4-6 business days depending on location. It will be longer to outside of metro and rural areas.

Express Post will usually be with you next business day in metro areas of QLD, NSW, SA, VIC and TAS. WA will take 2 days to metro and extra days after that to out side metro and rural areas.

Everything we ship has a tracking number with the exception of some power cables and smaller envelope packages. You will be emailed tracking once your order has been shipped!
