Audio I/O (formerly Audio Interface II) allows you to effectively interface your Eurorack modular system to the balanced line level world (+4 dBu).  You can send and return to rack mount/desktop fx units, patch to external line level instruments like synths and drum machines, interface to a DAW and much more.


  • 2 x Balanced TRS 1/4″ to Eurorack modular level input paths
  • 2 x Eurorack modular level signals to Balanced TRS 1/4″ output paths
  • 4 x six stage led VU meter to monitor all inputs and outputs simultaneously
  • Input path has up to 20 dB of gain, which allows you to patch in low level consumer level signals and boost them.
  • Output path steps a nominal Eurorack level (10 Vpp) down to +4 dBu  with up to +6 dB gain

NOTE: Current spec of 120mA @ +12V is for all 24 LEDs lit. Nominal current draw is 50mA @ +12V.
