Sound

The sound adds a fourth dimension to the flightdeck.  In the above picture you can see the two small amplifiers for the flight deck Channel 2 & channel 3.  Inexpensive but adds a nice element.

Channel 1

This left & right sound channel is driven off of the P3D Server and only plays engine sounds.

 

Channel 2

My Instructor station drives sounds to the speakers above the captain and first officer.  This left & right sound channel only plays call out sounds.  Warnings, GPWS, etc.

 

Channel 3

My Captain Server drives sounds to the speakers install in the back wall above the circuit breakers.  This left & right sound channel only play cabin calls.  These cabin cables are included in the Sim-Avionics sound package and add a flight crew element to the sound experience.  Very cool.
