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. |
