1. OVERVIEW
The 7707AT-A series Audio Fiber Transmitters extend multiple channels of analog audio over a single
fiber optic link. The 7707AT-A12 version accommodates twelve channels of analog audio, while the
7707AT-A8 version accommodates eight channels. Each 7707AT-A version is designed to operate with a
companion 7707AR-A Audio Receiver module, to permit transport of the audio over distances up to 50Km,
with minimum possible latency.
Monitoring and control of card status and parameters is provided locally, at the card-edge, or remotely via
