Sale price$6,250.00



Developed specifically for the unique requirements of professional motion picture playback, the SC-434 extends QSC’s commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-434 is a 4-way, selectable tri or quad-amplified screen channel loudspeaker system comprised of two main units–the MHV-1090 high-frequency system and the LF-4315 low-frequency system. The MHV-1090 mid-high-very high system features a high output, horn loaded 10” midrange cone driver and a coaxial neodymium high-frequency/very high-frequency compression driver. The MHV-1090 includes a driver protection network and a passive crossover for tri-amp operation. The protection circuitry prevents low-frequency signals from damaging the high-frequency and very high-frequency driver. A high power 10” cone driver allows operation as low as 250 Hz and the advanced phase plug coupling permits a crossover point of up to 1800 Hz to the high-frequency horn. This ensures that most of the dialog range is reproduced by a single element, for unmatched intelligibility.
