Crown Audio SST-SX User Manual

SST-SX

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 components 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.
