This Module is currently available.
This module is for users who want to save space and don't want or need the midi interface provided by the Master module.
It requires a 9V power supply (min 400ma) to provide the 5V needed for the AE modules. The power is taken to the modules via the Bus cable, which one (or two) you need depends on the case size you have. These items are all available in the Tangible Wave shop.
It also provides a Headphone amplifier (only in mono), and minijack sockets to make connecting the AE to other instruments easier. The Minijack is the same size as on the patch bays of synths like the Behringer Neutron and Arturia Minibrute. These two I/Os will protect the AE from incorrect voltages, for more information please see the 4 I/O module.
These merchants probably sell this module. Huh?
