Section 1. Aircraft Overview
1.6 Audio
1.6.1 Cabin Speakers
There are two cabin speakers for an additional source of audio in the event of an
inoperative headset or other pilot requirement. The Cabin Speakers are turned off
during normal operations. However, by pressing the "SPKR" button on the Pilot's
(the left side) keyboard, the COM1/COM2 audio is sent to the Pilot's speaker. By
pressing the "SPKR" button again, the Pilot's cabin speaker is turned off. An LED
positioned just above the SPKR button on the Keyboard is illuminated to indicate that
the speaker is selected. The volume control on the Pilot's keyboard can be used to
adjust the speaker volume.
The Copilot's keyboard (if installed) controls the audio sent to the Copilot's speaker in
the same manner as the Pilots controls.
Speaker functionality is outlined in Section 15.9 "Keyboard"
1.6.2 Handheld Microphones
There are two hand held microphones (Pilot's and Copilot's). Each handheld
microphone has a built-in Push-To-Talk switch. There is a separate handheld
microphone jack on each of the flight crew 's armrests so that the handheld
microphones (used primarily as backup for the headset microphones) can remain
plugged in along with the headset or boom microphones.
The left handheld microphone is permanently wired to the Left PFD, and the right
handheld microphone is permanently wired to the Right PFD. The COM SOURCE
switch located on the left switch panel does not affect these microphones; they
always remain connected to the on-side PFD.
When a member of the flight crew pushes the handheld Push-To-Talk button, the
microphone audio is transmitted over COM1 or COM2, depending on the flight
crew/member's radio selection.
