Parameters
The DSP (Digital Signal Processing)
module replaces the
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
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" ➊ 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 ➋. Several dozen different
options can be proposed. Once
the settings are made, one can
leave the menu simply by pressing
the scroll button ➋ as the display
shows "Exit?". To return to the first
line of the menu without exiting,
simply press on "Set-up" ➊.
Input mode
typical Choice of analog inputs LFE (Low
Frequency Effects) mono or stereo,
or digital coaxial (Digital).
Note 1: it
simultaneously connect the stereo
inputs and the LFE from the
amplifier for both stereo and multi-
the 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.
Low Pass Mode

is possible to
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 Electra SW 1000 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
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.
