Abstract:
An aviation audio selector device comprising:a first input for receiving a first audio output signal of a first communication transceiver;a first output for providing a selected microphone audio signal to said first communication transceiver;a second input for receiving a second audio output signal of a second communication transceiver;a second output for providing another microphone audio signal to said second communication transceiver;a pilot headset connection for connection to a pilot headset;a copilot headset connection for connection to a copilot headset;a first audio switching device coupled to selectively provide either said first audio output signal to said pilot headset connection and said second audio output signal to said copilot headset connection, or said second audio output signal to said pilot headset connection and said first audio output signal to said copilot headset connection, depending upon a control signal;a second audio switching device coupled to selectively provide either a pilot microphone audio signal from said pilot headset connection to said first output and a copilot microphone audio signal from said copilot headset connection to said second output, or said pilot microphone audio signal from said pilot headset connection to said second output and said copilot microphone audio signal from said copilot headset connection to said first output, depending upon said control signal;a first user-operated switch configured to allow a user to select either said first communication transceiver or said second communication transceiver for connection to said pilot headset connection and the other of said first and second communication transceivers for connection to the copilot headset;a control circuit coupled to said first user-operated switch and said first and second audio switching devices and configured to generate said control signal to control said first and second audio switching devices depending upon a user selection set by said first user-operated switch; anda second user-operated switch coupled to said control circuit, wherein said control signal is also dependent upon an activation of said second user-operated switch to allow said user to override said user selection set by said first switch, whereby upon an activation of said second user-operated switch said first and second audio switching devices swap between a selection of said first communication transceiver and said second communication transceiver for said pilot headset connection and said copilot headset connection.
