Rolls' SX45 is a two-way stereo crossover with mono sub output. It features a 12dB per octave roll-off, a frequency dividing range of 50Hz to 2.5kHz and clip indication for proper level settings. The crossover's compact size allows for easy mounting in any universal rack tray or install-cabinet, while the external power supply provides clean DC power to the unit for quiet operation.

Controls for the SX45 include input level, variable frequency adjustment, and high and low output level. All connections are made via RCA phono jacks. The crossover provides clean, high-impedance audio signals in a compact steel chassis. It is perfect for small sound reinforcement applications like nightclubs or restaurants.
