Focal PROFILE SUBWOOFERS, Руководство пользователя

Страница: 19 / 40

The DSP (Digital Signal Processing)
module replaces the typical analog
module generally found in subwoofers.
In addition to the exacting control in
settings, the module’s precision is
exceptional. Thanks to the ease of
use of the remote, one can control
at distance all the functions in order
to immediately compare the different
choices without leaving the listening
zone, which allows the installer to tune
with great precision.
The digital display of different values
of filtering or correction allows one
to easily recognize and establish the
favorite settings (this should be saved
in writing at the end of the manual).
Navigation
One only has to push once the button
“Set-up”
™
to enter the first mode of
the menu. Pushing the button several
times then displays the different types
of programming. Selecting a setting
is as easy as scrolling through the
choices
š
. Several dozen different
options can be proposed. Once the
settings are made, one can leave the
menu simply by pressing the scroll
button
š
as the display shows “Exit?”.
To return to the first line of the menu
without exiting, simply press on “Set-
up”
™
.
Low Pass Mode
Active digital crossover, adjustable from
50 to 150Hz, 5Hz steps, 24dB/octave
slope. Set the frequency according to
the characteristics and performance
of the associated speakers. On stereo
program, with speakers that already
perform well in bass frequencies,
choose a crossover value lower or
equal to 80 Hz to give lower bass
support without overloading the lower
octave.
In multi-channel mode, this value can
rise (to 100 or 120Hz) to give more
impact in the bass.
Use a value higher or equal to 120Hz
when the speakers are compact
satellites with little bass performance.
Note 1: the inactive mode (Off) can
be chosen when the active filters of the
amplifier are used.
Note 2 : the active crossovers of the
Profile subwoofer, due to their extreme
precision, can work simultaneously
with those of an AV amplifier. The
latter usually employs a crossover with
a 12dB/octave slope. In this case,
using simultaneously the crossovers,
and set at the same frequency, the
result is a sharp slope of 36dB/octave.
This facilitates the integration of the
subwoofer with the other speakers in
the system.
Input mode
Choice of analog inputs LFE (Low
Frequency Effects) mono or stereo, or
digital coaxial (Digital).
Note 1: it is possible to simultaneously
connect the stereo inputs and the LFE
from the amplifier for both stereo and
multi-channel listening. These choices
will be conserved in the memory as
“Hi-fi” and “Cinema”.
Note 2: the menus on the “slave”
subwoofers connected to the input
“Digital” are partially deactivated.
Only “Gain” and “Phase” are active
on each subwoofer to allow easy
adaptation to room acoustics.
