2.3.1. Controller settings
For acoustic adjustment the 100 Hz function can be selected.
100 Hz circuit
If the 100 Hz circuit is selected, the upper operating frequency of
the system is reduced from 115 Hz to 95 Hz.
It can be used when actively driven Vi-GSUBs are used to
supplement V-Point cabinets operated in full range mode. The
100 Hz mode can also be used to compensate for the effect of
close coupling between the Vi-GSUB and V-Point cabinets
operated in CUT mode.
