➢
To perform a multi-point calibration, the first step is to calibrate the device normally,
following either the Typical or Advanced procedure.
➢
After the first calibration, you can add more points by choosing the “Multi-point”
option at the Calibration dialog. Place the microphone to one edge of the listening
area and continue calibration.
➢
You can add as many points as you want to the calibration, and the system
automatically weights them by comparing them to the main calibration data. The
maximum recommended number of additional points is 7, more points would not
contribute much to the correction model.
Please note
: if the listening area consists of rather two alternate areas, instead of
one larger one, it is recommended to perform separate calibrations into two separate
profiles. In other words, the alternative area is calibrated into another profile, and the
user can then switch the optimum correction to one of the spots at a time.
8.Room Response menu (Measurements)
The
Room Response
menu and measurement tool allows you to measure and view the
response of currently active filters. You can also view the room responses measured
during the automatic Anti-Mode calibration process. The calibration measurements
always show the most important frequency range in terms of room correction – from
16 Hz to 200 Hz. The upper limit frequency of the calibration is shown as a dotted line
on the display.
You can create and view two custom measurements. The measurement frequency
range can be the same as for the calibration responses, but sometimes it can be
useful to measure the whole audio band. For example, it may be helpful when trying to
find the optimal places for acoustical treatments or for example the toe angle for the
loudspeakers.
Note that “Measurements” is not the same as “Calibration”. With the Measurements
tool you simply make measurements without applying any correction automatically.
PLEASE NOTE
: Bass response measurements are always shown
just as they were measured, without any ”sugar coating”. No
smoothing is applied to make things look prettier than they
actually are.
