Metcom Audio Controller Metcom Audio Controller

Rack mounted component of a Metcom Aviation Meteorological system

Resumen

The Metcom controller is a 19” rack mounted component of a Metcom Aviation Meteorological system. Its function is to:

Convert the audio signals generated by the Metcom server(s) to provide balanced outputs to third party ATIS radio systems.
Where two servers are used the controller can switch between signals output from a primary server to those from a secondary, failover server when it gets a command to do so from that server.
The controller also has voltage free contacts which close as a “Press to talk” (PTT) signal for the radio systems. This function is controlled by the active server.
The controller can also provide signals and control to an optional, external telephone interface, to allow user to dial in and listen to the ATIS messages.
The controller has a small loudspeaker and selector switch on its front panel to allow a local check of any broadcast channels. It allows checking of the channels coming from the two servers and also the channels being output from the system.
