Crown’s Three-Year, No-Fault, Full Warranty
Crown offers a Three-Year, No-Fault, Full Warranty for every new Crown amplifier product—an
unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown ampli-
fier product is warranted to meet or exceed original specifications for the first three years of ownership.
During this time, if your unit fails, or does not perform to original specifications, it will be repaired or
replaced at our expense. About the only things not covered by this warranty are those losses normally
covered by insurance and those caused by intentional abuse. And the coverage is transferable, should
you sell your unit.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside of the
USA, please contact your authorized Crown distributor for warranty information or call 574-294-8200.
The Crown SST-SX module is a fourth-order
Linkwitz-Riley type crossover with the
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.

tact the Crown Technical Support Group at
