Otto Passive Stereo DIY Kit

Product status: Retired

Thank you for purchasing this KIT!

This is the stereo version of the Otto Passive.

It does not have normalization/break-functions for each jack. Instead is has access to tip and ring signals for all 8 stereo-jacks from the pinstrip on the backside.

The stereo-version does not come with any cables or female headers.

MIDI-TRS jacks are just stereo jacks. Therefore you can use this module as a MIDI front panel that can serve any need for MIDI-TRS jacks in your rack. You can connect to the pins with female dupont cables (not included).

For more information and building instructions, please see the Otto Passive Mono-version.

See here for the pre-built version of Otto Passive Stereo.
