The
variant 112A
can reproduce frequencies
down to 63Hz , so in those applications where no
high sound pressure level is required (speech,
vocals, etc) and there is no need of extending the
low frequency range the system can be installed
without subwoofers. If it is required extending the
low end then the
variant 18A
is recommended.
It is also recommended when combining
systems to use two different signal lines and one
external DSP to align both systems.
In applications like live sound concerts, disco
dance music, where high sound pressure level is
required double eighteen subwoofers should be
used. DAS Audio recommends the
LX-218CA
. To
align both systems and external DSP and two
different line signals will be needed.
Note: the relationship between the number of
subwoofers and the number of
variant 112A
depends on the application and is a parameter to
be defined by the user.
When using a subwoofer other than the
variant
18A
in combination with the
variant 25A
units, it is
recommended that external processor be used to
filter the signal fed into the
variant 25A
units at 138
Hz.
If an externally amplified subwoofer unit is to be
used in combination with
variant 25A
satellites, the
signal treatment will depend on the characteristics
of the subwoofer used. In order to achieve a good
quality sound, DAS Audio recommends the use of
variant 18A
subwoofers.
