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 four different AUD-EXT models, each providing different connectivity options. Refer to the
following table for details.
*
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.
