USER’S MANUAL /
When starting the software, the S8 DSP proposes Butterworth with a standard slope of 12 dB/Oct. By
changing the filter slope, the change will only be made to the channel you are working on.
E.g: if you are adjusting the Front Woofer, the change will affect only this channel (right and left if they are linked).
In STANDARD mode
(see section.8.2.9)
:
Depending on the speaker or speaker system selected during configuration, a suitable type of filter will be available.
E.g.: for the Front Woofer both Hi-P and Lo-P Models will be available, for the Front Tw only Hi-P Model will be
available, etc. An optimized cut-off frequency is set by default to avoid speaker breakdown and limits on
selectable frequencies will be applied.
In EXPERT mode
(see section 8.2.9)
:
Any loudspeaker or speaker system you select has any type of filter and cut-of frequencies available.
Remark: with the slope set to 0dB the filter is disabled.
WARNING: in EXPERT mode, due attention must be paid to filter adjustment. Loudspeakers have mechanical limits
which must not be exceeded and which could lead to their breaking.
The response of the crossover filter for the selected channel is graphically displayed by a red curve,
as in the examples below.
Crossover frequency 80 Hz @ 6 dB Oct.
Hi-pass 2000 Hz @ 24 dB Oct. Low-pass.
Crossover frequency 80 Hz @ 12dB Oct
Hi-pass - 2000 Hz @ 12 dB Oct Low-pass
Crossover frequency 80 Hz @ 24 dB Oct.
Hi-pass 2000 Hz @ 24 dB Oct. Low-pass
Crossover frequency 80 Hz @ 24 dB Oct.
Hi-pass 2000 Hz @ 6 dB Oct. Low-pass.
