2.3.1 Controller settings
For acoustic adjustment the 100 Hz mode can be selected.
100 Hz mode
It can be used when actively driven Bi8-SUB cabinets are used to
supplement TOP cabinets operated in full range mode, for
example in a distributed sound system. The 100 Hz mode can also
be used to compensate for the effect of close coupling between the
Bi8-SUB and TOP cabinets operated in CUT mode.
