6.3 WX3A - Sub Bass and Full Range/High Pass
Configuration (Stereo)
The WX3ASF plug-in board is used to control the W1, passive W2 and
passive W3 when operating either as stand-alone full-range systems or with
additional WS2 sub-bass enclosures.
It is also used to provide the outputs for other WX3A controllers configured
to drive active W2 and W3 systems used in stereo with WS2 sub-bass
enclosures.
PCB mounted jumper links on the plug-in board select various alignment
options for the full-range/high pass outputs (Bands 2 and 4). See Fig 6.
Fig. 6
If full-range mode (1) is selected, +6dB of low frequency boost at 65Hz is
applied to the full-range outputs (Bands 2 & 4).
If 100Hz high-pass crossover mode (2) is selected, the full-range outputs
are re-configured as 100Hz high-pass outputs.
In Overlap Mode (3), the sub-bass and full-range enclosures are allowed to
overlap and 3dB of LF boost is applied to the full-range enclosure. This
can be useful when the full-range systems are flown some distance from
the sub-bass. This mode allows some low frequency energy to be
reproduced by the flown loudspeakers without using up as much headroom
as would be required if the full-range +6dB low frequency boost were
applied.
