Otto Passive Mono

Product status: Active

manikk Otto Passive Mono is an 2HP module that can be used in several use cases:

  • Passive multiple where you can create your own splits
  • Patch bay
  • Input/output module with normalizations
  • DIY
  • Front-panel for your own creations
  • See here for more inspiration

On the back there is a pin-strip with access to all jacks signals and break/normalizing-signals.

The first versions included a 15 pin female header that could be used to create passive multiples when attached to the pinstrip at the back of the Otto Mono. New versions have seven solder-pad-switches instead. You can solder each of these solder-switches to connect two nearby jacks, for example 1 and 2. With these solder-switches you can easily create passive multiples from 2 jacks connected, up to all 8 jacks connected. You can create any combination of groups with nearby connected jacks.

No cables are included.

Read the manual for more information.

There is also a Stereo-jacks version called Otto Passive Stereo.

See here how to attach stickers to the front.
