Doepfer A-138i

Interrupting Mixer

6 HP Eurorack module

Four-channel mixer with a mute switch per input, two types of single output, and a dual mix output.

Features

  • Individual mute switch for every input channel.
  • DC-coupled inputs and outputs.
  • Patching a channel's Single Output A removes that channel from the summed mix.
  • Single Output B is available only on channels 1 and 2 and leaves its channel in the summed mix.
  • The mix output is duplicated on two hard-wired sockets.

Controls & Jacks (20)

  • Channel 1 Level— Linear 0–1 attenuator for Channel 1.
  • Channel 3 Level— Linear 0–1 attenuator for Channel 3.
  • Channel 2 Level— Linear 0–1 attenuator for Channel 2.
  • Channel 4 Level— Linear 0–1 attenuator for Channel 4.
  • Channel 2 Single Output A— Interrupting direct output for Channel 2; patching it removes Channel 2 from the mix sum.
  • Mix Output 2— Second of two hard-wired duplicate DC-coupled mix outputs.
  • Channel 2 Input— DC-coupled signal input for Channel 2.
  • Channel 1 Single Output A— Interrupting direct output for Channel 1; patching it removes Channel 1 from the mix sum.
  • Channel 4 Single Output A— Interrupting direct output for Channel 4; patching it removes Channel 4 from the mix sum.
  • Channel 4 Input— DC-coupled signal input for Channel 4.
  • Channel 3 Mute— Mutes or enables Channel 3 in its direct outputs and mix contribution.
  • Channel 1 Single Output B— Non-interrupting direct output for Channel 1; patching it does not remove Channel 1 from the mix sum.
  • Channel 3 Single Output A— Interrupting direct output for Channel 3; patching it removes Channel 3 from the mix sum.
  • Channel 3 Input— DC-coupled signal input for Channel 3.
  • Mix Output 1— First of two hard-wired duplicate DC-coupled mix outputs.
  • Channel 2 Single Output B— Non-interrupting direct output for Channel 2; patching it does not remove Channel 2 from the mix sum.
  • Channel 1 Input— DC-coupled signal input for Channel 1.
  • Channel 4 Mute— Mutes or enables Channel 4 in its direct outputs and mix contribution.
  • Channel 1 Mute— Mutes or enables Channel 1 in its direct outputs and mix contribution.
  • Channel 2 Mute— Mutes or enables Channel 2 in its direct outputs and mix contribution.
