SAS-8C

RDL SAS-8C – 8 Station Audio Controller for SourceFlex Distributed Audio System

The RDL SAS-8C is a professional audio controller designed to manage eight remote listening stations in the SourceFlex distributed audio system. It allows independent control of the maximum listening level at each station, offering flexibility and convenience in large-scale audio installations.

Each station connects via a six-conductor cable, with the power line protected by an auto-resetting fuse. The SAS-8C features balanced or unbalanced line-level audio inputs – one for paging and eight switchable sources – with adjustable input level. It includes a paging control input, LED indicators for signal level and output voltage, and loop-thru output for daisy-chaining with SAS-82 or additional SAS-8C units.

Designed for cost-effective scalability, the SAS-8C is ideal for large SourceFlex systems, providing the lowest cost per listening station.
