This product is very simple and easy to understand. Extend your Sound Devices 8-series recorder with two extra trim and volume knobs, e.g. ch 7 and 8 for the 833. Plug and power via USB, control channel trim and channel volume, no further setup required. Knobs are very quiet endless encoders. Small design changes may occur from batch to batch (only for improvements)


  • Toggle between trim and fader with the button
  • Access PFL by pressing the encoders.
  • Long press each encoder button for mappable functions (via SD controller menu)
