Automatic Position Correction
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 EQ 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 EQ 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 EQ Button
LED will go the colour of the previously selected EQ 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.
