Automatic
Position
Correction
(APC)
will optimise the acoustic output of the subwoofer
to
match the ideal system performance by removing the dominant room modes from the
listening position. The
APC will take measurements from 3 different seating locations
within the room to achieve the most accurate
correction.
NOTE:
Please
run the
APC
before running the automatic room set up of your
AV
amplifier.
To
perform
APC,
follow the steps listed below:
1.
Pressing
the Calibration Button (item
2,
page
6)
while
in
normal operation will enter
calibration mode. A flashing blue
LED
in
the calibration button indicates that the
subwoofer
is
ready to perform
an
APC
measurement.
2.
Place
the microphone
in
the normal listening position, then press the
EO
button to
activate a room measurement. This
will
flash cyan and
a series of tones
will be
heard.
If
it doesn't get a good enough reading, the
EO
button
LED
will
blink
red
and the
sub will run the test tones again until it gets
an
accurate enough measurement. The
LED
will
then blink green, then purple (processing the equalisation) and
go
off. The
Calibration button
will
be flashing blue indicating that it needs to run a second and
third set of tones.
3.
Repeat step 2
in
another 2 listening positions
to
provide more room information for
the subwoofer.
Good locations for the 2nd and 3rd measurements would be 1m
to
the immediate
left and right of the initial listening position.
The subwoofer will then calculate the error between the current listening position and the
ideal frequency response of the system, then calculate and apply digital filters to optimise
the listening experience for the room.
When it has completed the APC the Calibration Button
LED
will go off, and the
EO
Button
LED
will
go the colour of the previously selected
EO
profile.
If
you
do
not wish
to
run a second and third APC
frequency sweep, you can cancel the
test by pressing the Calibration Button again.
