4 SST-SBSC
The Crown SST-SBSC modules
are stereo crossover networks
with equalization and summed
bass output. Truly professional
crossovers, SST-SBSC modules use
hard-wired precision components
that stay at the factory-set frequen-
cies for consistent bandwidth
control.
SST (System Solution Topologies)
modules install into the back of
Crown SST-compatible amplifi ers,
saving rack space and simplifying
system wiring.
Several SST-SBSC modules with
different crossover frequencies are
available (see Table 1 on page
15).
