Using Bass Management Filter Settings
The Bass Management Filter (subwoofer crossover frequency) is normally set in the subwoofer
group settings. When the Bass Management setting is marked ‘global’, the Bass Management
Filter setting is applied to all monitors in the group.
In certain special cases you may want to turn off the bass management for certain monitors, for
example when you do not want to bass-manage rear monitors in a room having a subwoofer
located in the front of the room.
To turn off the bass management for a specific monitor
 select the monitor by clicking on its icon
 set ‘Bass management setting’ to ‘individual’
 set ‘Bass management filter’ switch to ‘OFF’
We recommend using the ‘global’ setting for all normal applications. In certain exceptional cases
there can be acoustical reasons for setting the Bass Management Filter to ‘individual’ in a monitor.
This enables you to set the Bass Management Filter individually for this monitor to a value that
differs from the rest of the system. Using the ‘individual’ setting is an expert feature as the Bass
Management Filter for this monitor no longer tracks the selection made in the subwoofer settings.
Advanced use of AutoCal
AutoCal automatic calibration offers you the possibility of using multiple microphone positions
(multipoint) in order to determine the system calibration instead of one microphone position
located, for example, at the main listening position (single point).
Multipoint calibration uses up to four spatially averaged microphone positions. The first microphone
position is the primary position. Timing and level are calibrated to the primary microphone position.
Put the microphone first to the primary position.
Multipoint calibration
The steps of a multipoint calibration are
 select ‘Multipoint’ in the AutoCal window (additional microphone positions appear in the
layout grid)
 place the microphone in the primary listening position
 press the center position microphone icon (the others are grayed out)
 wait until the measurement sweeps occur and all products are measured
 move the microphone to the next position
 press the next microphone icon
 measurements are taken for this position
 once all the positions have been measured (either 2, 3, or 4) press the ‘Optimize’ button to
start the calculation process
