Difference between manikk Otto models
NOTE! Make sure to order the correct module for your purpose.
manikk Otto Passive Mono
The 8 jacks are mono with break/normalizing function for each jack.
The Otto Passive Mono also exists as a DIY KIT that you mount and solder yourself.
manikk Otto Passive Stereo
Same as Otto Passive Mono but with 8 stereo jacks instead.
No normalizing functions.
Access to tip and ring for each of the 8 jacks via a pinstrip on the backside.
Great for MIDI-TRS applications which requires min stereo jacks on a front panel.
Digital8 is a digital expander with 8 digital output jacks. It is controlled by a SPI interface via pins on the backside.
Like the Otto Passive Mono, it also have the 8 tip signals and 8 break signals on the top 32 pins in the pinstrip on the backside.
manikk ADSR Expander
This module is based on the Digital8 module, but has a dedicated front panel with descriptive names for each jack instead of the numbers 1-8.
The ADSR Expander is used as an expander to the manikk ADSR module. This module has digital outputs for all 8 jacks. The outputs are controlled (set or reset) by the master ADSR module. On the backside it has the same pins as the Otto Passive, but in addition it also has some pins at the bottom, for SPI-communication with the master module.
See here how to connect the ADSR Expander to your master module.
Analog8 is an active buffer expander. It has 8 signal pins on the backside where you can connect signals from other modules in your rack. These signals are buffered and then sent to the 8 front output jacks.
This module is suitable for making break out boards, extra buffered jacks or your own DIY projects.
manikk Otto Passive Multiple 4+4
Passive multiple with two hardsoldered groups of 4 jacks. No pinstrip on the backside. More information here.
