Application Setup Cabinets per
channel
B6-SUB B6-SUB 2
Within applicable amplifiers, the controller setup is available in
Dual Channel or Mix TOP/SUB mode.
2.3.1. Controller settings
For acoustic adjustment the 100 Hz and CSA function can be
selected.
100 Hz circuit
If the 100 Hz circuit is selected, the upper operating frequency of
the system is reduced from 140 Hz to 110 Hz.
It can be used when actively driven B6-SUB subwoofers 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
B6-SUB and TOP cabinets operated in CUT mode.
CSA circuit
CSA (
Cardioid Subwoofer Array) mode enables the combination
of three or multiples of three subwoofer cabinets into an array that
produces exceptional low frequency directivity control.
The amplifier channel for the center subwoofer of the array, which
is physically pointed to the rear, has CSA selected. The forward
facing cabinets are driven with an amplifier channel set in the
standard mode. The resulting cardioid behavior of the array will
significantly reduce the energy radiated to the rear.
For further information please refer to the d&b TI 330 Cardioid
Subwoofer Array, which is available for download at
