USER MANUAL AUD-EXT-100 Crestron

The Crestron® AUD-EXT Series provides a solution for extending analog or digital (S/PDIF) audio signals (depending on model) up to 2000 ft (610 m) over CAT5 cable. It is ideal for any application that requires connecting a remotely located source to a receiver or audio distribution system.

There are three different AUD-EXT models, each providing different connectivity options. Refer to the following table for details.

MODEL	DESCRIPTION
AUD-EXT-100	(1) Unbalanced stereo signal; 2000 ft (610 m) max
AUD-EXT-200	(2) Unbalanced stereo signals; 2000 ft (610 m) max
AUD-EXT-201	(1) Unbalanced stereo signal and (2) S/PDIF signals; 600 ft (183 m) max*

* If using only the unbalanced connection, the maximum length is 2000 ft (610 m).

Each audio extender is comprised of one transmitter and one receiver. Each component can be mounted discretely in the back of an equipment rack or on any suitable flat surface. Linking the two components requires just one run of high quality CAT5 cable (sold separately). Crestron offers a full line of rugged cables and installation tools for a complete solution.
