This QSC SC-443C 3-Way Screen Channel Loudspeaker, Bi- or Tri-Amp is developed specifically for the unique requirements of professional motion picture playback, the SC-443 extends QSC’s commitment to the cinema market. As a member of the DCS Digital Cinema Speaker Series, the SC-443 is a three-way, selectable bi or tri-amplified screen channel loudspeaker system comprised of three main units—the MH-1075 high-frequency system and dual LF-4215 low-frequency systems.
The MH-1075 mid-high system features a high output, horn loaded 10" midrange cone driver and a 3" (75mm) titanium diaphragm compression driver mounted to an adjustable pan and tilt bracket. The MH-1075 includes a driver protection network and a passive crossover for bi-amp operation. Power limiter circuitry protects the high-frequency driver from overpowering.
The MH-1075 provides extended frequency coverage for the critical midrange band. 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
