Unamplified Outputs 
For applications requiring line level zone outputs, Crestron offers the SWE-8 Sonnex 
Multiroom Audio Unamplified Expander (sold separately). Each SWE-8 provides an 
assortment of analog line level, S/PDIF digital, and Crestron Home (CH) CAT5 
balanced audio outputs, offering a solution for routing audio to AV receivers, 
powered subwoofers, headphone amplifiers, phone systems (for music-on-hold), and 
other audio equipment. 
70/100 V Option 
Any amplified zone output can be converted to 70- or 100-volt output using one or 
more Sonnex Output Transformers (SAT-70V/100V-2 or SAT-70V/100V-4, sold 
separately). A 70/100 V (constant-voltage) speaker system allows for the connection 
of numerous speakers per circuit and long wire runs using small-gauge wire. Typical 
applications include outdoor speaker zones, commercial retail spaces, hallways, and 
common areas. 
Intelligent Monitoring and Protection 
To help ensure the most seamless user experience and long-lived operation, Sonnex 
includes several ways to keep tabs on its operating status and health. On its own, 
Sonnex possesses the intelligence to protect itself from many types of faults 
including over temperature, over current, over voltage, under voltage, and dc offset 
on any channel. In the event of a fault, the front panel LCD provides clear fault 
indication to speed the troubleshooting of incorrect wiring, poor rack ventilation, and 
other unforeseen issues. Fault alerts may also be sent to a system touch screen or 
mobile device, and integrators can even monitor and track the data remotely through 
Crestron’s Fusion RV
®
 software to ensure a rapid service response. 
Ultimate Integration 
Without question, Sonnex delivers unprecedented intelligence from source to 
speaker. Via Cresnet
®*
 or high-speed Ethernet, Sonnex affords incredible integration 
potential as part of a complete Crestron system, enabling seamless control of every 
room and source through a wide selection of touch screens, keypads, wireless 
remotes, computers, and mobile devices. Complete setup is afforded via USB or 
Ethernet, using Sonnex Tools software, part of the Crestron Toolbox™ installer 
toolkit. 
*  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.
