• Maketheroomasquietaspossible.Backgroundnoisecandisrupt
theroommeasurements.Closewindows,silencecellphones,

• Cellphonesshouldbeturnedofforplacedawayfromallaudio
electronicsduringthemeasurementprocessasRadioFrequency
Interference(RFI)maycausemeasurementdisruptions(evenifthe
cellphoneisnotinuse).
• Refrainfromtalkinganddon’tsitorstanddirectlybetweenanyof
thespeakersandthemicrophoneduringtheroommeasurements.
Eachspeakeremitsaseriesoftestsignalsduringthemeasure-
mentsandyourbodyandbackgroundnoisecandisruptthemi-
crophone’sabilitytorecordtheroomresponsetothetestsignal.
Therst(Position1)measurementmustbelocatedattheprimarylisteningposi-
tion,asthisisthemeasurementthatestablishesbothdistanceandlevelsettings
foryoursurroundprocessor.Placethemicrophone’stipatalocationhalfway
betweenwheretheprimarylistener’searswouldbe,pointingattheceiling.
ClicktheMeasurebutton.Eachspeakerwillbe“chirped”tentimes,followedby
abriefpauseduringwhichitremainsimportanttobequiet.Thisisbecausethe
systemismeasuringbackgroundnoiselevelstoascertainthequalityofthedata
itjustobtained.
Measuring additional positions Whenthesystemhassuccessfullymeasuredeachspeaker,theapplicationwill
bereadytomeasurethenextmeasurementposition.Startatthecenterofthe
listeningareaandthentakemeasurementsarounditspacedby1-2feet.The
ideaistosamplemultiplepointsthroughoutthelisteningarea.Measurements
nearthesideandbackwallsshouldbeavoidedevenifpeoplemaysitthere.
