the multichannel bass processor is used, the center and surround speakers, and mute the subwoofer.
For this use case the connector (10) is provided.
6.8
Using big main speakers
For large main speakers, the BASIS 11K, BASIS 13K or BASIS 14K should be used exclusively for the
subwoofer channel (LFE). The connection of the individual speakers to the subwoofer is therefore
not advisable, as an additional bass reproduction, in addition to the large main speakers, serves no
purpose.
6.9
Acoustical room adjustment of the subwoofer
After the subwoofer is properly positioned and connected,
the volume (5) will be adjusted to that
of the main speakers. Then adjust the volume of the additional LFE channel (subwoofer) (4). We
recommend gradual adjustment of the level. As an advantage start this procedure with stereo mode.
Usually listeners have the most listening experiences in this mode, so that they react very sensitively
to errors in the sound image.
In case it was not possible to place the BASIS 11K, BASIS 13K or BASIS 14K at the same level as the
stereo speakers,
please use the “Distance” knob (2) to correct the distance (see chapter 5.2). Please
note that the maximum correction for the distance of the subwoofer to the level of the front speakers
(in the direction of the listening zone) is 1 m.
On delivery, the f
u
switch (lower limit frequency) is set to 25 Hz. If you require a higher overall level
, a
lower limit frequency of 40 Hz may be useful (1). This adjustment applies when using the subwoofer
as the central bass unit in stereo or surround mode,
as well as in LFE mode. Via the controller (3)
you can adjust the crossover frequency between 60 and 80 Hz. This setting is possible when using
the subwoofer as the central bass unit. By default, we recommend a crossover frequency of 80 Hz.
The optimum range should be set by acoustic measurements. The upper limit frequency of the LFE
channel is not adjustable and is 120 Hz.
For studio applications with reference status, professional measurement in the control room is
appropriate.
