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 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 amplifi ers,
saving rack space and simplifying system wiring.

800-342-6939 or 574-294-8200. Also, visit the

Specifi cations
Note: Specifi cations describe typical results using the
SST-SX crossover module installed in a Crown SSTcompatible amplifi er. 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
specifi ed. Specifi cations for units supplied outside
the U.S.A. may vary slightly at different AC voltages
and frequencies.
Performance
Frequency Response: ±0.1 dB from 20 Hz to 20
kHz at 1 watt.
Signal to Noise Ratio,
A-Weighted: Better than 105 dB below rated 1-kHz
power;
20 Hz to 20 kHz: Better than 100 dB below rated
1-kHz power.
Total Harmonic Distortion (THD): 1-kHz rated
power, 1.0% or less true THD from 20 Hz to 20
kHz.
Crosstalk: Better than 50 dB below rated power,
20 Hz to 20 kHz.
Input/Output
Input Impedance:
Nominally 20 k ohms, balanced. Nominally 10 k
ohms, unbalanced.
Output Impedance: 600 ohms, balanced.
Maximum Output: +15 dBm into 600 ohms.
