16 + 17 High Pass & Low Pass
The high/low pass filters filtrate the signal before
distribution to main and sub-channels. The high-pass
filter is typically used when relatively small main
monitors are used. The performance of such small
main monitors will improve significantly, when they
don’t have to reproduce very low frequency signals.
High-Pass
The high-pass filter filters the low-end frequencies
from the main channels above the x-over frequency
and according to the high-pass options.
- “off” - no high-pass filter
- “12 dB/octave” for a 12 dB slope above the X-
over point
- “24 dB/octave” for a 12 dB slope above the X-
over point
Low-Pass
The low-pass filter filtrates the high-end frequencies
from the signal below the x-over frequency according
to the low-pass options.
- “12 dB/octave” for a 12 dB slope below the X-
over point
- “24 dB/octave” for a 24 dB slope below the X-
over point
18 Levels
Individual level adjustment for the LFE channel and
the extracted signal below the X-over frequency.
14 Bass Management
For bass management to be active a few conditions must
be setup:
- main channels must be assigned:
- for bass management of the main channels to be
active, mark the bass management-box
- a subwoofer is connected to “line out 8” and thus any
LFE channel should be routed to this output by
setting Assign to “Sub”.
15 X-OVER
Sets the X-over frequency for the main channels to
determine the frequency where the main channel
signal is split. Frequencies below this point is routed
to the sub channel (line out 8).
