Functional description

The Otto Passive Mono is a completely passive module.

It has 8 mono jacks on the front and a pin-strip on the back with access to all jack signals.

For each jack you will find pins for the main signal and a break/normalization signal.

Each mono jack has a break- or normalization-function. When no connector is inserted in the jack on the front, the main-jack-signal is also sent out to the break/normalization pin. But if a connector is inserted, nothing is sent out on the break/normalization pin.

The GND for all jacks and pins are connected to the same ground-plane. That ground-plane is also connected to the front and the jack screws. When you install the module in your rack, it will also be grounded to your rack.

The module can be used in many use-cases where you need mono-jacks with the connections freely accessible at the back.

Installation

Installation

If you have purchased a module, you need to install it in your eurorack case. Use the supplied screws to mount it in your rack.

An expander or add-on needs to be attached to the back of a master module via pin-strips. Either directly or via dupont-cables.

Power supply

There are three types of power requirements for manikk products:

  • Completely passive products requires no power.
  • Normal eurorack modules requires +12V and -12V from your eurorack system. Connect with IDE ribbon cable.
  • Some kits and add-ons requires only +5V from a master module. Connect directly or with dupont-cables.

NOTE!

  • Make sure to use approved and good power supply in your system.
  • Always turn off the power to your system when installing or uninstalling modules.
  • Make sure to get the polarization correct when connecting cables.
  • When you connect an IDE flat ribbon cable to the eurorack power distribution, the negative -12V is normally indicated with text on the PCB and with a red stripe on the cable.
