Mono/Stereo crossover – 2 & 3/4-way
SC-234XL is a professional 2 ways stereo, 3/4 ways mono crossover. The unit is equipped with balanced XLR-3 connectors and it's built to endure the most demanding touring situations. SC-234XL sports a low frequency summed (subwoofer) output and has a x10 range switch on both channels to multiply the desired frequency by ten. Individual level control, phase reverse on all outputs, Low cut filter and 24dB per octave Linkwitz-Riley filters complete the most salient features of this ideal equipment for any professional rack.
