With this technique, the PRIR is gathered in at least two stages.
Stage 1: virtual L, C and R.
Press

Connect the microphones, put the microphones in your ears and sit in the desired listening
position facing forward. Press

Stage 2: virtual Ls and Rs.
Press

Turn 180° and face away from the speakers. Move forward or backward so that the angles
between you and the speakers are what you desire for the virtual surround speakers. Typically
you will move toward the speakers to obtain wider surround angles.
The angles for looking left and right while facing rearward are
not
determined by the angles
now existing between you and the speakers. If you are using the
AZI
mode for look angles,
look the same angles left and right as you did while measuring the front speakers, since these
angles will have been entered as the azimuth. For example, if the front speakers are ±30°, you
will have looked ±30° when looking at the front speakers, and you would look ±30° again while
looking toward the rear of the room even though you may be positioned such that the speakers
are at other angles.
If you are using the
HT
mode for look angles, wear the head-top unit facing the set-top
(backwards with respect to you, forward with respect to the room) when you are facing
backwards. In
HT
mode the Realiser will measure the look angles and they are independently
measured for each sweep, so the look angles need not be the same for looking forward and
rearward, but the narrowest look angles will limit the head-tracking for the composite PRIR, so
look at least ±30°.
Press
OK
. The personalisation sweeps will run, followed by the diagnostic screens.
If you had set
SAVE AT END
to
YES
, then the channels on/off screen will reappear with the
following settings (verify).
