I-ō47 - Multimode Resonator / Filter (i-047)

Description

I-ō47 Multimode Resonator/Filter is a modern take on a vintage circuit design inspired by the classic 1047 module of the ARP2500. It has been designed with some extra features and quirks built in.

The internal VCA’s are a new hybrid design of matched transistors and precision op-amps.

With CV controllable centre frequency, resonance/Q and notch offset along side FM, strike and a complex dual input with wave shaping limiter, the I-ō47 is truly a filter for all occasions.

Features

  • Centre frequency range 16Hz to 16KHz
  • 1V/octave, Coarse and Fine frequency controls
  • FM input with attenuverter
  • Low pass 18 dB/octave
  • High pass 18 dB/octave
  • Band pass ~6 – 18 dB/octave dependent on Q
  • Notch with variable offset –/+ 2 octaves
  • Input with gain control
  • Inverted input with resonance dependent gain
  • Strike input for pinging the filter
  • Feedback switch which adds BP to the input for enhances resonance
  • Limiter based on tanh wave shaper which affects primary input (post gain fader)

Specifications

  • Width: 14HP
  • Depth: 27mm
  • Power: +12V: 50mA –12V: 50mA
