Lecture Discussion 6 Flight Deck Calls Panel Emg Call Cabin Call Gnd Call Cabin Headset Ground Crew Jacks Operation with Other Systems Slide 17 Turbine Section Operation Connect a personal electronic device (PED) to the AUD INPUT connector, press the PAX BRIEF switch (annunciator light on) to enable the input. Play back the prerecorded message, then press the PAX BRIEF switch again (annunciator light off) to disable the input. The PED can then be disconnected from the system. Instructor: Select each Note button on screen. Note: The PAX BRIEF input is not intended for any long term playback (more than approximately 15 minutes). The audio output stage of the Passenger Address amplifier is not designed to be utilized for long periods of time and will overheat. Note: When playing back the prerecorded message it may be necessary to set the output volume of the PED at or near maximum to overcome any noise gate internal to the Passenger Address system. If an audio equalizer is included in the PED player application (e.g. Windows Media Player) then it might be helpful to boost the equalizer bands in the frequency range between 250 and 4000 Hz approximately 3 to 6dB.
