Overview:

The model DA-422-IRIG-2X4 is designed to accept a RS-422 signal input signal.
Amplify and send to 4 outputs the same signal with the same or very closely the same
delay characteristics. An analog input accepts an audio frequency signal, passes it
through a variable gain AGC system, through separate potentiometers, drives the
transformer coupled output stages.
