To
adjust room response measurement settings, select
the MSR menu option to display the measurment screen.
The
2.2 XP is factory configured to measurement
parameters as displayed in Fig. 5. The MSR
MIC CAL option should be turned ON and the
MIC FILE field should display the microphone
serial number as printed on your microphone.

8. Mode menu. 2.0 mode selection is displayed
in the upper left corner (1).
MSR
MIC CAL When this option is set to ON, the room correction
algorithm will apply the microphone calibration
file to the measurement data. When this option
is set to OFF, the microphone calibration
file is ignored.
MIC FILE This field displays
the microphone file name used to perform microphone
calibration. The microphone calibration file
data is saved in 2.2 XP internal memory. For
more details on how to transfer microphone
calibrations file to 2.2 XP memory, please
refer to the Microphone section of the PC
software manual.
AVG This is a very important
measurement parameter. It equals the number
of measurements that are averaged prior to
being saved. The averaging process reduces
the effects of random environmental noise.
Typical Average values go from 10 to 30.
DELAY If you do not want
to be in the room while measurement is in
progress, set this parameter to a few seconds
to allow you to exit the room. For example,
if DELAY = 10 the system will wait for 10
seconds before it starts pulsing.
PULSE This parameter sets
the relative level of the output measurement
pulse. Minimum level is 1% and maximum level
is 100%.
FILE Use this option to assign
a File number to the measurement you are just
about to perform. At the end of the measurement
process, the measurement data for all four
channels will be saved in the selected File
number. Tact-2.2 XP supports up to seven measurement
files. In another words you can save up to
seven different measurements in 2.2 XP internal
memory.
Use L, R, SL and SR options to select (enable)
a channel for measurement. Channels are labeled
as L for left, R for right, SL for subwoofer
left and SR for subwoofer right channel. Selected
(enabled) channels are marked by a rectangle.
To select or deselect a channel place the
cursor over desired channel and press ENTER
button.
In
most cases factory presets are optimum and
users can proceed directly with performing
actual measurements. To initiate the room
measurement process click on the START button. The following screen will be displayed:
Microphone
calibration and measurement screen.
After
the measurements are completed, click on the EXIT option and then click
on the MENU button to go
back to the DRC-RCS screen.
At any time during the measurement process
you can click on the CANCEL option to cancel the process. After the measurement
is completed or the measurement was canceled,
the CANCEL option changes
its name to EXIT.
