SR8100_No_Grille SC2150_front QSC Introduces Two New Cinema Loudspeaker Systems

Built expressly to meet the needs of professional motion picture playback in smaller theatres, QSC's new SC-2150 loudspeaker is one of two new members of the DCS (Digital Cinema Speaker) Series.

Offering high-power handling, excellent sensitivity, and extended bass response in a very compact enclosure, the SC-2150 is a three-way, selectably passive full-range or bi-amplified screen channel loudspeaker comprised of two main units: A mid-high frequency system and a 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. QSC's patented Cine-Sight simplifies aiming of the horns for proper audience coverage.

The dual 15” (381 mm) low-frequency enclosure is built to address the extended low-frequency response required for cinema applications. The compact LF device is only 14.5” (368 mm) deep, reducing the space required behind the screen. The enclosure is constructed of high quality MDF panels and employs 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.

Thanks to a design feature within which the bass ports are evenly spaced on each side of the transducers, internal pressure within the enclosure is more uniform across the back surface of the drivers. 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 additionally 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.

Three bolts are all that are required to secure the SC-2150's 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.

QSC's new SR-8100 cinema surround loudspeaker is the second newcomer to the DCS Series built expressly for use in smaller theatres. Offering high power handling, excellent sensitivity, and extended bass response in a very compact enclosure, the device features a long-throw 8” low-frequency transducer coupled with a 1” soft dome tweeter. The system's MDF enclosure incorporates a 15° down angle baffle and easily accessible top-mounted terminals. The 125-watt continuous power rating and sophisticated crossover with protection circuitry provides absolute reliability, while the black-finished enclosure with black grille blends easily into any theatre environment.

A proprietary QSC design, QSC's QuickMount bracket allows for fast, easy and secure installation of the SR-8100. The loudspeaker half of the bracket comes pre-installed on each SR-8100, while the QuickMount QM-SW wall bracket is purchased separately to facilitate shipment to the job site ahead of the loudspeakers. A traditional U-bracket, the YM-300, is also available in lieu of the QuickMount bracket system. The SR-8100 is shipped in pairs to reduce shipping costs.
