Garmin's GMA 340 audio panel meets the needs
of aircraft owners and operators who require reliability and
versatility in the essential audio switching function.
The GMA 340 features innovative LED-illuminated
push button controls that allow audio selection of both NAV
and Comm audio. Large buttons activate the Comm microphone and
audios for up to three Comm transceivers to simplify cockpit
workload. Another feature of the GMA 340 is the Split Comm,
which allows the pilot to transmit/receive on Comm 1 and the
co-pilot to transmit/receive on Comm 2. MASQ™ processing reduces
ambient noise from the avionics inputs. Comm transmit indication
is also provided. Speaker selection is available to monitor
the aircraft radios or to make PA announcements. There are two
unswitched inputs for telephone ringers, altitude alert warnings,
or other warning tones. In addition, the GMA 340 includes a
six-place VOX intercom with three selectable modes of isolation,
dual stereo music inputs, and independent pilot, co-pilot, and
passenger volume control. Each microphone input has a dedicated
VOX circuit to ensure that only the active microphone is heard
when squelch is broken. Special cabin noise de-emphasis circuitry
enhances cockpit communications. Also standard is the three-light
Marker Beacon Receiver/Indicator with high/low sensitivity selection
and SmartMute™ marker audio muting.
Surface mount technology provides shallow depth
and light weight, which simplifies installation in the tightest
aircraft spaces and saves precious panel space. Operation is
available in 14 or 28 volts without voltage converters or dropping
resistors. Installation is simplified with the built-in intercom
and marker beacon, and the GMA 340 also features photo cell
dimming of annunciators, pilot fail-safe mode connection to
Comm 1, and FAA TSO approval.
Read what Private Pilot magazine had to say about
the GMA 340:
"The Garmin® Model 340 audio panel, reviewed
above, is the finest example of communications integration and
control for GA. The ICS system offers everything: individual
level controls, positive com override of crew/music audio, stereo
or monaural operations, soft-on/off, music/voice, crew-isolation,
positive VOX control—you name it! The marker beacon and multifunction
communications controls complete an excellent design. This unit
will be as popular as Garmin's GPS units." -Private Pilot, March
1999
