SST Modules 1 Welcome Crown®’s System Solution Topology (SST) modules bring you superior control and flexibility with the convenience and cost savings of plug-in processing. SSTs plug quickly and easily into the back of your amp. loss found with passive crossover networks). Compact and versatile, Crown SST modules continue the Crown tradition for fast setup, greatsounding output and exceptional value.
SST Modules 2 SST-MX The SST-MX module is a fourth-order Linkwitz-Riley type crossover with a fixed crossover point set at 100 Hz. Figure 2.1 SST-MX Front Panel Controls and Connectors 2.1 Controls HP Filter Bypass Switch This switch enables/disables the high-pass filter on the local amplified output signal. Select IN to enable high-pass filter; select BYPASS to disable filter for these outputs. Figure 2.
SST Modules 2.2 System Setup Typical input wiring is shown in Figure 2.2 on the previous page. Stereo Mode Standard stereo-mode output configuration (shown in Figure 2.
SST Modules Bridge-Mono Mode Standard bridge-mono-mode output configuration (shown in Figure 2.4) routes the signal in the following manner: low-frequency signal from the amplifier’s Channel 1 input is sent to the Channel 1 barrier block output; high-frequency signal from Channel 1 input is sent to the local (amplified) Channel 1 output. Note: Only the Channel 1 audio signal is required to drive the amplifier during mono operation.
SST Modules High-Pass Filter Bypass When activated, the High-Pass Filter Bypass (Section 2.1) allows the fullrange signal to be sent to the local (amplified) Channel 1 and Channel 2 outputs, while still providing filtered low-frequency output to the Channel 1 and Channel 2 barrier block outputs. This configuration works well if you have full-range speakers driven by the main amplifier, plus dual subs on an auxiliary amp for sub-bass output. 2.3 Block Diagram 100HzLP 24dB/oct.
SST Modules 3 SST-SX The SST-SX module is a fourthorder Linkwitz-Riley type crossover switchable between 80 Hz and 120 Hz. It also includes summed lowfrequency output. Figure 3.1 SST-SX Controls and Connectors 3.1 Controls 80/120 Hz Crossover Selector HP Filter Bypass Switch A two-position switch, located on the front panel of the module, is used to select a crossover frequency of 80 or 120 Hz for both channels 1 and 2 of the local (amplified) signals.
SST Modules 3.2 System Setup Typical input wiring is shown in Figure 3.2 on the previous page. Stereo Mode For standard stereo-mode output wiring, connect your system components as shown in Figure 3.3.
SST Modules Bridge-Mono Mode For standard bridge-mono-mode output wiring, connect your system components as shown in Figure 3.4. This configuration routes the signals in the following manner: low-frequency signals from the host amplifier are sent to the male XLR output; high-frequency signal from the host amplifier’s Channel 1 input are sent to the local (amplified) Channel 1 output. Note: Only the Channel 1 audio signals are required to drive the amplifier during mono operation.
SST Modules High-Pass Filter Bypass When activated, the High-Pass Filter Bypass (Section 3.1) allows the fullrange signal to be sent to the local (amplified) Channel 1 and Channel 2 outputs, while still providing filtered low-frequency output to the Mono Summed Male XLR Output. This configuration works well if you have full-range speakers driven by the main amplifier, plus a sub on an auxiliary amp for sub-bass output. 3.3 Block Diagram 80 / 120 Hz HP 24 dB/oct.
SST Modules 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 frequencies 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.

SST Modules 4.5 System Setup Typical input wiring is shown in Figure 4.3 on the previous page. Stereo Standard stereo-mode output configuration (Figure 4.4) routes the signal in the following manner: Lows from SST-SBSC CH1 go through the local amp to its CH1 speaker output. Lows from SST-SBSC CH2 go through the local amp to its CH2 speaker output. Highs from SST-SBSC CH1 go to its Output A, and from there through aux amp CH1 to its CH1 speaker output.
