12The Acoustic Lens Technology systemin BeoLab 5 ensures better balancebetween sound in the high and midtone frequencies coming directlyfrom the loudspeaker, and soundreflected by the room. The AcousticLens Technology system also ensurescorrect tonal balance in the wholearea in front of the loudspeaker.The BeoLab 5 Adaptive Bass Controlsystem and the Acoustic LensTechnology system ensures optimumfreedom in the placement of yourloudspeakers. Performing acalibration of the Adaptive BassControl system ensures that theloudspeaker is optimally suited to itsplacement and the surroundings –and therefore, gives the best possiblesound quality.Adapt BeoLab 5 to your roomAdaptive Bass Control calibrationNormally, when a loudspeaker is placed in acorner, the bass level is boosted compared tothe bass level in a loudspeaker placed in amore freestanding position.With other speaker systems, you have toconsider this when placing them. WithBeoLab 5, the Adaptive Bass Control system– when calibrated – filters out this change inthe bass level.During the calibration, the loudspeakergenerates a series of sound signals andmeasures the response from walls, the floor,the ceiling, large objects and other surfaces inthe room. Based on these measurements, theloudspeaker automatically calculates optimalsettings for the Adaptive Bass Control filter.Important!– Before you start the calibration, place theloudspeaker where you want it to be.– Do not calibrate more than one loudspeaker at atime. Otherwise, the sound emitted from oneloudspeaker interferes with the measurementsdone in the other, and vice versa.– Consider the ‘normal status’ of the listeningroom: Will the doors be closed…?The windows…? Will the curtains be drawn…?Will there be many people in the room…?– If you, later on, decide to move theloudspeakers, rearrange your room, carpet thefloor, etc., we recommend that you perform thecalibration for each loudspeaker once again.– We recommend that you keep any tone controlsettings neutral.During the calibration make sure that no noiseinterferes with the sounds emitted by theloudspeaker. Such noise might, for example, be:a running vacuum cleaner, ventilation or airconditioning systems, motor sounds nearby, etc.Up to a certain level, the loudspeaker will try tocompensate for this noise, but eventually, thenoise may cause the calibration to fail – indicatedby a slowly flashing red light. Should this happen,you must restart the calibration – perhaps later on,when the noise has stopped…The ‘Adaptive Bass Control’ calibration ensuresthat the bass level suits the placement of theloudspeaker, and thus the surroundings.When you switch the loudspeaker on for the firsttime, the indicator light flashes slowly green* –signalling that it has not yet been calibrated.Acoustic Lens Technology –manufactured under licensefrom Sausalito Audio Works.
