MUSIC 1 Muting
MUSIC 1 muting occurs when aircraft radio or marker
beacon activity is heard. MUSIC 1 is always soft-muted
when an interruption occurs from an aircraft radio. Soft
muting is the gradual return of MUSIC 1 to its original
volume level. The time required for MUSIC 1 volume to
return at the headset outputs is between one-half and four
seconds.
MUSIC 1 Muting Enable/Disable
Pressing and holding the
seconds toggles MUSIC 1 muting ON and OFF. When
toggling, either one (1) or two (2) beeps can be heard; one

GDL 69A XM RADIO SYSTEM
When no external entertainment music is connected
to the audio panel through MUSIC 1 and MUSIC 2
jacks, audio from the GDL 69A is heard by the pilot and
passengers simultaneously.
Connecting a stereo input to either MUSIC 1 or
MUSIC 2 removes the GDL 69A audio from that input.
For example, if passengers prefer music while the pilot
listens to the GDL 69A, the entertainment audio would be
connected to the MUSIC 2 jack.
Refer to the Optional Equipment Section for more
details on the GDL 69A.
