3. GENERAL DESCRIPTION

TheAMSeriesisaReal-timeSteeringArrayMicrophonethatefcientlypicksuptargetedsoundbyusinga

unique algorithm to detect the position of the sound source and control the microphone’s directivity.

This microphone system consists of an array microphone unit and its control unit. The array microphone is

availableintwodifferentversions:AM-1B(black)andAM-1W(white).

4. FEATURES

• Thearraymicrophoneutilizeseightmicrophoneelementstorealizeanarrayeffectbymeansofitsnarrow50°

horizontal angle of directivity.

• The microphone employs a unique algorithm to detect and track the position of the sound source and

automatically control the directivity of the array microphone in real time so that the targeted sound can be

efcientlypickedup.

• Thefree-to-download,dedicatedAM-1iOSappallowsnotonlyvisualmonitoringofsoundsourcedetection

conditions,butalsoeasyfunctionsettings.FunctionsettingscanalsobeperformedbywayofaPCbrowser.

• Thearraymicrophonecanbemutedbywayofitsmuteswitchorsoftwarecontrol(viatheAM-1iOSapp).

5. HANDLING PRECAUTIONS

• Warning: ThisisaclassAproducts.Inadomesticenvironmentthisproductmaycauseradiointerferencein

which case the user may be required to take adequate measures.

• Note: This equipment has been tested and found to comply with the limits for a Class A digital device,

pursuanttoPart15oftheFCCRules.Theselimitsaredesignedtoprovidereasonableprotection

against harmful interference when the equipment is operated in a commercial environment.

This equipment generates, uses, and can radiate radio frequency energy and, if not installed

and used in accordance with the instruction manual, may cause harmful interference to radio

communications.

Operation of this equipment in a residential area is likely to cause harmful interference in which

case the user will be required to correct the interference at his own expense.

• Theuserthatchangesormodicationsnotexpresslyapprovedbythepartyresponsibleforcompliancecould

void the user's authority to operate the equipment.

• Avoidblockingthearraymicrophonewiththehandorotherobjectsthatmayrestrictthemicrophone’soptimal

performance.

• Whenmountingthecontrolunitinarack,peripheralareasaroundpoweramplierscouldexceedtheoperating

temperaturespeciedfortheunit.Avoidinstallingthecontrolunitincloseproximitytopowerampliers.

• Takecarenottodroptheunitontotheoororbumpitagainstahardobjectastheunitcouldfail.

• Avoidusingamobiletelephonenearthisunitsinuse.Noisecouldbepickedup.

• Toclean,besuretorstcutoffpowertotheunit,thenwipewithadrycloth.

When the unit gets very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner or

chemically-treated cleaning cloth because such volatile liquids could deform or discolor the unit.
