Bohumin [bo’xumin] is an expander for our Ostrawa full stereo mixer module. By connecting to Bohumin, Ostrawa gains a second full stereo AUX bus with voltage control over the amount of the effect on each channel. In addition, Bohumin features manual attenuators for stereo returns of both aux a (note: the send and return jacks for aux a are located directly on Ostrawa) and aux b, as well as four gate inputs for automated clickless muting of each stereo input channel.

For detailed description, please refer to the manual.
