Parameters
Boost Mode
Increase of the bass level by 0dB to +6dB at 30Hz, 40Hz or 50Hz. To be used as preference or need on
multi-channel playback for very dynamic bass.
Subsonic Mode
Low-pass filter, adjustable from 0 (OFF) to 45Hz by 10Hz steps, at a slope of 48dB/octave. This filter can
be very practical when the subwoofer is placed in a small room and-or at an angle in the room, or if the
walls of the room are thin or not very rigid. The room may generate an excessive sound level in the lower
bass or even cause saturation. Vibration and unpleasant resonances can then occur. The subsonic filter
can progressively eliminate this annoyance and maintain a clean and strong bass performance. Adjust
the filter value until the resonances disappear in the listening room.
Note 1 : this filter setting can be used as well during extended listening periods at high levels. It inhibits
excessive cone movement of the diaphragm (bottoming out) and delays the appearance of distortion.
Note 2 : this filter can be used simultaneously with the mode “Boost” activated. The increase in energy
(+ 3dB, equal to a doubling of power) is compensated by the subsonic filter, which suppresses energy
in the upper bass.
Phase Mode
Adjustment of the phase from 0° to 180°, with very precise steps of 30°. This adjustment allows to
precisely lock in the phase of the subwoofer with that of the other loudspeakers at the crossover
frequency. Navigate through the phase values with the directional arrows until the bass of the subwoofer
perfectly meets that of the loudspeakers.
Note 1 : this adjustment can be done by ear. However, measuring instruments make for easy work, and
are recommended: discuss this with your reseller.
Note 2 : it is possible, whilst listening, to compare the position 0° and 180° (inverted phase) directly from
the menu, without fine-tuning by steps. This easy phase inversion solution can simplify final adjustment.
Gain Mode
It is possible to assign a different gain (from -6dB to +6dB) according to either a music or cinema
program that would benefit from a higher level. This level can be kept in memory on the buttons Select
Hi-fi and Cinema.
Remote Control Locking System
To avoid that the multiple remote controls of the audio/video equipments interfere with the SW 1000
Be, the new “Remote Control Locking System” function has been added to the DSP parameters. The
menu configuration ends with the “Remote Lock” line. When you are on the “Lock” mode, the infrared
reception is inactive. To reactivate reception, simply press the Set Up button of your remote control to
access the "Remote" menu and select the "Unlock" mode.
Presets buttons (memory)
After exiting a menu, you can assign your adjustments to one of the three available memory settings.
Press, and hold one of the three “Preset” buttons 3 for two seconds. When the display flashes, the
setting has been memorized.
Note 1 : the preset buttons correspond to the everyday use of either a stereo or home theatre system.
Naturally, according to the use or nature of the system, these three buttons can be assigned to settings
for either stereo or home theatre.
Note 2 : the “User” function is an additional memory setting that can be assigned to another use of the
subwoofer, e.g.: multi-channel SACD or DVD-Audio, which may require different settings.
