SST-SX  
he Crown SST-SX module is a fourth-order  
Linkwitz-Riley type crossover with the  
T
crossover point switchable to either 80 or  
120 Hz. High-frequency (HF) signals are routed to  
the internal amplifer channels, and low-frequency  
(LF) signals are summed and routed the mono  
output connector. Truly a professional crossover,  
the SST-SX uses hard-wired precision compo-  
nents that stay at the frequencies you have  
selected for consistent bandwidth control.  
SST (System Solution Topologies) modules install  
into the back of Crown SST-compatible amplifiers,  
saving rack space and simplifying system wiring.  
Neutrik® Combo (¼-inch (6.35-mm) phone  
and 3-pin XLR) input jacks.  
Features  
Stereo biamp.  
Male 3-pin XLR Sub Output.

Crossover switchable to either 80 or 120 Hz.  
Optional high-pass filter bypass on amplified  
outputs adapts system for full-range use.  
SST modules install into the back of your  
amplifier, saving rack space and simplifying  
system wiring.  
SST Modules add flexibility by allowing you to  
tailor your Crown Contractor (CH/CL) Series  
or CE Series amplifier to your application.
