The PMA450 begins our journey into the digital-audio domain. Our company is known as the source of the vast majority of innovations in audio control systems for General Aviation and the PMA450 opens up completely new dimensions for audio panels with valuable features and an intuitive interface. Although the PMA450 has a superset of the capabilities of the PMA8000BT, pilot’s access to new advanced features is significantly more intuitive. Pilots who currently are flying with the PMA8000BT will have all of the advantages of their current system along with all of the new capabilities of the PMA450. IntelliAudio is a patented technology that we have licensed from the United States Air Force. Originally designed for fighter pilots who are inundated with multiple types of audio signals, the PMA450 now brings this technology to GA Pilots. IntelliAudio® provides dimensional sound for easy discernment of simultaneous radio sources 3 Customizable Named Switched Inputs Optional Marker Beacon Receiver Volume Light Bar Indicate Various Volume Levels 3 Customizable Switched inputs. Pilot creates custom labels to fit specific aircraft equipment list. 6-place hi-fi stereo intercom with limitless distribution capability and 3 music mute modes. USB charger for portable devices including iPhones® or iPads®. Adjustable Volume levels for Speaker, Music 1, 2, and Bluetooth inputs, and 2 of the 4 unswitched inputs and the optional Marker Beacon Receiver Two hardwired Music inputs as well as Bluetooth® music Audiophile intercom, aircraft radio and music fidelity. Extremely quiet intercom system. No computer programming required, front panel configurable. Simply stated, when wearing stereo headsets, Com 1 will appear to come from the pilot’s 10 o’clock position while Com 2 will appear to come from the 2 o’clock position. Because the method used to create this audio environment not only makes it possible for the pilot to hear both radios at the same time, it allows the brain to more easily discern one com from the other. With IntelliAudio®’s digital audio processing, the radio and intercom audio is incredibly clean, clear and crisp. Our highly acclaimed patented automatic VOX (IntelliVox®) is also an integral part of the intercom system of the PMA450, completely eliminating manual intercom squelch adjustments. Through the use of 3 soft-keys and a graphic display, the pilot visualizes the set up of the audio panel. This makes making changes to the audio configuration simple. This approach means a pilot guide is almost unnecessary. In addition to Nav 1 and 2 switched inputs, there are three pilot definable switched inputs that can be named to reflect actual equipment in the aircraft. Finally, there is no requirement for an avionics shop to connect a computer for initialization of the audio panel. All audio panel adjustments can be done by way of the front panel, eliminating the need to connect to an external computer. *GARMIN and GMA340 are trademarks of Garmin International, Inc.
