2 LoudspeakerSystems SC-0 Screen Channel Loudspeaker SC-50 Screen Channel Loudspeaker SC-50 Screen Channel Loudspeaker The SC-0 is a two-way, full-range screen channel loudspeaker with a passive crossover network. Optimized for small rooms up to 5 feet ( meters) in length from the screen to the last row of seating, the SC-0 consists of a single -inch (05 mm) low frequency transducer and a.75-inch diaphragm high frequency compression driver. The system includes a specially-designed high power passive crossover network, so it can be powered from a single amplifier channel. The enclosure was designed to be platform mounted, and its shallow depth (less than inches or 00 mm) dramatically reduces space requirements behind the screen. The SC-50 is a two-way, full-range screen channel loudspeaker with a passive crossover network. Optimized for slightly larger rooms up to 45 feet (4 meters) in length from the screen to the last row of seating, the SC-50 consists of a single 5-inch (80 mm) low frequency transducer and a.75-inch diaphragm high frequency compression driver. The system includes a specially-designed high power passive crossover network, so it can be powered from a single amplifier channel. The front baffle is treated with sound absorbing material, reducing behind screen acoustical reflections. The enclosure s shallow depth (less than inches or 00 mm) dramatically reduces space requirements behind the screen. For rooms up to 55 feet (7 meters) in length from the screen to the last row of seating, the SC-50 screen channel loudspeaker provides the ideal balance of high performance and economy. The SC-50 is a -way, selectable passive or bi-amplified screen channel system comprised of a low frequency enclosure and a mid/high frequency component. The dual 5-inch (80 mm) lowfrequency enclosure is only 4.5 (68 mm) deep, reducing the space required behind the screen compared to conventional cinema loudspeakers. The mid-high component features a high output, horn loaded 6.5-inch (65 mm) midrange cone driver and a.4 (5.6 mm) diaphragm high frequency compression driver mounted to an adjustable pan and tilt bracket. QSC-patented Cine-Sight simplifies aiming of the horns for proper audience coverage. The SC-50 includes a switchable passive crossover for full-range or biamplified operation. A simple flip of the switch determines the operating mode. Power limiter circuitry protects the high-frequency and mid-frequency drivers from overpowering. The -way design provides exceptional reproduction of the critical midrange band for improved dialog intelligibility.

3 LoudspeakerSystems PowerAmplifiers SB-80 Subwoofer SB-80 Subwoofer SR-80 Surround Loudspeaker DCA 644 / DCA 84 The DCA Series 4-channel power amplifiers offer four channels of power in a compact package that doesn t consume precious rack space. And, compared to the cost of multiple two-channel amplifiers, you ll find they leave more room in your budget as well. Channels Watts/Channel 8Ω 4Ω Ω The SB-80 and SB-80 subwoofers offer the maximum extended low frequency response from unusually shallow enclosures. Both models feature high excursion 8-inch low frequency drivers with 4-inch (00 mm) voice coils, providing output down to 0 Hz, making them the perfect extended low-frequency match for any of our Small Room screen channel loudspeakers. For small rooms and budget-driven applications, there simply isn t a more economical surround loudspeaker than the SR-80. The two-way SR-80 combines a high power 8-inch (0 mm) low frequency driver with a -inch (5 mm) soft dome tweeter. Its narrow width profile allows the enclosure to be unobtrusive in any small room cinema application. Pre-installed speaker-side hardware allows fast single-installer mounting, and brackets support down-angles of either 5 (standard) or (optional). Connections include parallel outputs to make multi-speaker configurations easy. Each DCA 4-channel amp is equipped with two DataPort connectors for use with a QSC DCP (Digital Cinema Processor), providing a total system solution that greatly reduces labor and wiring costs. The DCA 644 delivers 50 watts at 8 ohms from each channel, so you can power three SC-0 or SC-50 screen channel loudspeakers in a single chassis that occupies only two rack spaces (.5 inches or 89 mm). A single DCA 84 is ideal for powering up to sixteen SR-80 surround loudspeakers, since each channel can deliver up to 450 watts at Ω to four parallel 8Ω speakers.

It is designed for systems of no more than eight channels (up to 7.) in which all amplifiers will connect directly to the DCP via QSC DataPort. In one three rack space chassis, the DCP 00 combines digital signal processing, a booth monitor, crossovers, and status monitoring for up to three bi-amplified screen loudspeakers, minimizing cost, space, and installation time.
