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
Push once the button "Set-up" ➎ to enter the first mode of the menu (fig. H). 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, you 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" ➎.
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.
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 SW 1000 Be 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.
