SC-2150 Cinema Loudspeaker SystemDeveloped specifically for the unique requirements of professional motion picture playback in smaller cinemas, QSC extends its commitment to the cinema market with the introduction of the SC-2150 Screen Channel Loudspeaker. As a member of QSC’s DCS (Digital Cinema Speaker) Series, the SC-2150 offers high-power handling, excellent sensitivity, and extended bass response in a very compact enclosure. The SC-2150 is a 3-way, selectable passive full-range or bi-amplified screen channel loudspeaker system comprised of two main units – the mid-high frequency system and the low-frequency enclosure. The components are easily assembled on-site via a pan and tilt bracket that mounts the mid-high components to the top of the LF enclosure. The mid-high system features a high output, horn loaded 6.5" midrange cone driver and a 1.4" (35.6 mm) diaphragm compression driver mounted to an adjustable pan and tilt bracket. QSC’s patented Cine-Sight simplifies aiming of the horns for proper audience coverage. The dual 15" (381 mm) low-frequency enclosure is designed specifically to address the extended low-frequency response required for cinema applications. The compact enclosure is only 14.5" (368 mm) deep, reducing the space required behind the screen. The enclosure is constructed of high quality MDF panels and features Single Woofer Chambers (SWC, separate chambers for each transducer). In the rare event of a transducer theft or failure, this prevents over-excursion of the remaining transducer caused by improper box loading. With Symmetrical Port Loading (SPL), bass ports are evenly spaced on each side of the transducers, making internal pressure more uniform across the back surface of the transducer. This prevents the cone from being displaced to one side or another by unbalanced forces, reducing the chance of driving the voice coil out of the center of the gap at high power. The SC-2150 includes a driver protection network and a passive crossover for bi-amp and full passive operation. Power limiter circuitry protects the high-frequency and mid-frequency drivers from overpowering. A simple switch setting determines the operating mode and eliminates dual inventory and ordering issues associated with fixed bi-amp or passive models. The 3-way design provides exceptional coverage of the critical midrange band for improved dialog intelligibility. The SC-2150 is designed for ease of installation. Three bolts are all that are required to secure the mid-high system to the top of the LF enclosure. A pre-wired harness and connector plugs into the terminal plate to provide all electrical connections to the mid-high system. Pre-installed rubber feet speed installation, thereby reducing labor costs.
