Today is all about the Gables audio selector panel and seeing it in action. For the test setup I have configured 3 audio channels that are fed to the VHF-1, VHF-2 and VOR-1 channel on the audio panel. Here is a description from the L-1011 flight manual on how the audio panel works (taken from a Delta Airlines L-1011 Operating Manual):
1. Microphone Switchlights
Push to select desired transmitter. Integral light illuminates. VHF switch lights also select respective receive function without independently selecting the corresponding receive switch. A mechanical interlock prevents the selection of more than one transmitter at the same time.
2. Control Knobs
Push to monitor audio. Push again to discontinue monitoring audio. All receivers may be simultaneously monitored. Rotate knob to adjust volume.
3. Voice Only
Filters out the out the Morse code (CW) signal.
Below is a short video demonstrating the features of the Gables audio selector panel that I intend to use for the L-1011 project:

Note: The computer voice that says "This is VHF one" and other is there for testing only. I mix it into the audio channel that is connect to help me assure that I am cabled correctly. Also, the ATC feeds are not from X-plane or VATSIM quite yet ... they are live ATC audio feeds from the Internet.
