Audio Interface II Manual

Overview

The Audio Interface II is designed to interface your modular system with line-level equipment using balanced 1/4″ TRS cables.

Installation

See the Module Installation Guide for instructions on installing the module in your Eurorack modular system.

Controls

  1. INPUT GAIN L/R
    These knobs set the gain of the signal coming in to the modular via the BAL IN L/R jacks. The knob range is from -∞ (no signal) to +6 dB. The signal levels are indicated on the meters above the OUT L/R jacks.
  2. OUTPUT GAIN L/R
    These knobs set the gain of the signal leaving the modular via the BAL OUT L/R jacks. The knob range is from -∞ (no signal) to +6 dB. The signal levels are indicated on the meters above the IN L/R jacks.

Inputs & Outputs

  1. OUT L/R
    These jacks are the modular level outputs of the signals coming in to the system via the corresponding channel of the BAL IN L/R jacks. The signals are boosted to modular levels according to the INPUT GAIN knobs.
  2. BAL IN L/R
    These jacks bring signals in to your modular system from the outside world to their corresponding OUT L/R jacks. Connect a 1/4″ balanced TRS cable. from the output of your other synthesizers, effects pedals, audio interfaces, etc. to these jacks.
  3. IN L/R
    These jacks are the modular level inputs that send your modular’s audio to the outside world. A modular audio signal connected to these jacks will appear at line level on the corresponding BAL OUT jacks, with gain controlled by the OUTPUT GAIN knobs.
  4. BAL OUT L/R
    These jacks carry signals from your modular to your other audio equipment. Use a 1/4″ balanced TRS cable to connect each one to an input of an effects pedal, audio interface, tape recorder, etc.

Patch Notes

  • Even though the channels are labelled “L” and “R” they don’t need to be used for stereo sources. You can use them for completely different purposes.
  • Process your modular via external effects: connect a module audio output to IN L. Connect BAL OUT L to the effect input. Connect the effect output to BAL IN L. Connect OUT L to another point in your patch.
