SPQ Processing 45
The preceding figures show configurations for a stereo speaker set. When configuring the speaker set, select the speaker format
from the preset or custom format list. The 5.1 speaker set is the selected output speaker set in the following figure. The speaker out-
put sets can be configured freely in the monitor profile editor. An additional curve is shown in the graph reflecting the presence of
the LFE channel.
When a speaker set format with one or more speaker SUB channels is selected like 5.1 with one LFE channel, it is also possible to
apply bass management functionality to the speaker set.
Bass Management for a speaker set is enabled by activating the
BMngt button as shown in the figure above. Once this is enabled
the curve for the selected speaker will reflect the high pass filter applied in the white resulting curve. When selecting the LFE/SUB
channel the response for the low pass filtered curve is shown. The low pass filter curve is also shown the in the non-SUB channels
as an additional information.
Configuring Bass Management
The configuration of the Bass Management system is done in the Monitor Profile Configuration window. A Bass Management con-
figuration can be made for all speaker output sets, where the speaker format comprises one or more LFE/SUB channels. In relation
to the format conventions a translation is made between what is the LFE channel in the signal source, and what are the subwoofer
speakers in the speaker setup, and in that relation the mapping between LFE, Bass managed speaker channels and subwoofer speak-
ers is also made. For example, the traditional subwoofer setup for a 5.1 speaker system has the subwoofer connected to the LFE
source channel, but Bass Management can be applied as well filtering the low frequency from the surround speakers to the sub-
woofer speaker. This is the Basic Bass Management configuration also applied in Pro Mon.
In order to configure the Bass Management setup in general or to make a starting point for a more complex Bass Management sys-
tem, such as with multiple subwoofer speakers, configuration is done in the Bass Management configuration window selected for
the relevant speaker set, as shown in the following picture.
