N°7 Crossblock Settings - Focal Utopia Beryllium Serie Manuel De L'utilisateur

N°7 Crossblock settings
N°7 Crossblock is an exclusive high
technology crossover offering 4480
different filtering combinations to
adapt kit's characteristics to car's
environment and to your own tastes.
We advise you to refer to the
Quality Control Certificate provided
with each kit in order to know the
reference setting (Fig. 1).
This setting corresponds to an
optimized linearity
according to normalized measuring
conditions (see file for
informations) and is a good base
to refer to before begining settings.
The response curve may change
according to vehicle
speakers location, woofer/tweeter
distance and speakers orientation.
An adapted Crossblock setting will
allow to have a flat response curve.
We advise you to use a measure
equipment (RTA) for a fine setting.
We advise you to note different
settings in order to refer to them as
often as you need.
S1 setting
It combines two settings in one.
It changes
frequency values
Steps "1" to "5" refer to different
low-pass frequency values, whereas
steps "6" to "10" also refer to the
same "1" to "5" values but a boost
is included. Steps "6" to "10" are
interesting in solving level losses due
obtained to woofer location (low in the door
for example). Steps "1" and "6"
more refer to the higher frequency pass,
whereas steps "5" and "10" refer to
the lower one (fig. 2).
acoustic, S2 setting (Hi-pass)
This setting
frequency values
Step "1" refers to the higher
frequency pass, whereas "7" refers
to the lower one. The midrange low-
pass value remains fix (fig. 3).
S3 setting (Level)
Midrange level setting according to
low-pass crossover 8 values, 1dB per step. Step "1"
(12dB/octave). refers to the higher boost whereas
"8" refers to the lower one (fig. 4).
S4 setting (Level)
It is the tweeter level setting. Eight
steps increase or decrease tweeter
level (1dB per step). Step "1" refers
to maximum level, whereas "8"
refers to minimum one (fig. 5).
changes high-pass
(12dB/octave).
