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.

Specifications
Note: Specifications describe typical results using the
SST-SX crossover module installed in a Crown SST-
compatible amplifier. All measurements are in Stereo
mode with 8-ohm loads and an input sensitivity of
26-dB gain at 1-kHz rated power unless otherwise
specified. Specifications for units supplied outside
the U.S.A. may vary slightly at different AC voltages
and frequencies.
