The recording requirements ofparagraph(a)(2) of this section may be met:

(1)
By installing a cockpit-mounted area microphone located in the best position for recording voice communications originating at the .rst and second pilot stations and voice communications of other crewmembers on the .ight deck when directed to those stations; or

(2)
By installing a continually energized or voice-actuated lip microphone at the .rst and second pilot stations. The microphone speci.ed in this paragraph must be so located and, if necessary, the preampli.ers and .lters of the re-corder must be adjusted or supplemented so that the recorded communica-tions are intelligible when recorded under .ight cockpit noise conditions and played back. The level of intelligibility must be approved by the Administra-tor.Repeated aural or visualplayback of the record maybe usedin evaluating intelligibility.

(c)
Each cockpitvoicerecordermustbeinstalled sothatthepart of the communication oraudiosignalsspeci.edinparagraph(a) of this sectionobtainedfromeach of the following sources is recorded on a separate channel :

(1)
For the .rst channel, from each microphone, headset, or speaker used at the .rst pilot station.

(2)
For the second channel,from each microphone,headset, or speaker used at the second pilot station.

(3)
For the thirdchannel,from the cockpit-mounted area microphone, or the conti-nually energized orvoice-actuatedlip microphoneatthe .rstand secondpilot stations.

(4)
For the fourth channel, from :

(i)
Each microphone, headset, or speaker used at the stations for the third and fourth crewmembers; or

(ii)
Ifthe stations speci.edinparagraph(c)(4)(i) ofthis section are not requi-red orif the signal at such a stationispicked up by another channel, each microphoneonthe .ightdeck thatisused with thepassengerloudspeaker system if its signals are not picked up by another channel.
