2.4 AntiMode
TM
: Automatic Room Correction
The room response is one of the biggest influences in reproduction of sound, altering the
tonal balance especially at the lower frequencies. In order to accomplish perfect sound
characteristics in every circumstance, the active speaker should be able to measure the
room and adjust itself to the existing acoustic conditions.
DSP
eaker Servo 300 is equipped
with the highly acclaimed builtin AntiMode
TM
algorithm, which is capable of automatically
and effectively measuring the room and correcting the effect of roominduced distortion,
including standing waves.
Before calibration, the output gain must be at 0dB, or the calibration will not begin.
AntiMode
TM
calibration is performed by connecting the included measurement microphone
into its dedicated 3.5mm jack at the back panel. After this the microphone is placed into the
listening zone. The input gain of the speaker is set to minimum to avoid any input signal that
could disturb the following series of automatic measurements. The calibration will begin
when the control button is pressed and held for about four seconds. The calibration will
feature two consecutive measurement sweeps, each taking approximately one minute. It is
adviced not to make any loud noises while the calibration is in progress. The calibration
process automatically adjusts the volume to optimal levels.
The calibration can be cancelled anytime by pressing the control button again. Once the
calibration is finished, the correction settings are stored in to the internal memory of the
speaker, in which they will remain even if the power is switched off or the power cable
disconnected. The settings can only be replaced by a new calibration, which is
recommended if the speaker or listening zone is moved. Remember to calibrate each Servo
300 speaker individually, and do this before the calibration of your A/V receiver.
Adjusting the level of bass after AntiMode
TM
calibration:
It is important to recalibrate A/V receiver after all Servo 300 speakers have been calibrated
first with the AntiMode algorithm. Otherwise the level of the bass may be incorrect, as the
receiver would have adjusted it relative to the existing room modes which are reduced after
AntiMode calibration.
