Features and Functions 
(Continued) 
1.  Additional S/PDIF and analog line outputs may be added using the SWE-8 Sonnex Multiroom Audio 
Unamplified Expander (sold separately). 
2.  For connection of the Sonnex Link between the SWAMP-24X8 and each expander, use Crestron  
DM-CBL-8G or high-quality CAT5e shielded twisted-pair cable. The maximum cable length using 
DM-CBL-8G or CAT5e is 200 ft (61 m) per run. For longer distances, use the S-EXT1-S Sonnex 
Link over Fiber Extender (sold separately). 
3.  If using Cresnet
®
 as the control system interface, system expansion is limited to one expander. 
Support for more than one expander requires Ethernet as the control system interface. 
4.  CH (Crestron Home
®
) CAT5 balanced audio is supported using balanced inputs 13 – 16. All other 
inputs require an ABAR-1 CAT5 Balanced Audio Receiver.
