User manual BOSE 802C II BROCHURE

[. . . ] The 802C Series II systems controller assures smooth, accurate spectral response across the entire operating range of the 802 Series II loudspeaker. Sharp subsonic and ultrasonic band-limiting filters reduce power waste, stage noise, high-frequency instability, and interference. The systems controller also provides two independent signal channels. · Modular components for system design flexibility · High linear excursion and power output · Electronic systems controller Technical Information Frequency range 55Hz ­ 16kHz Active equalization (with 802 C Series II systems controller) Required Nominal impedance 8 Maximum acoustic output 114d B-SPL average, 123d B-SPL peak Power handling capacity 240W continuous pink noise, 55Hz ­ 16kHz Recommended amplifier power 240W minimum, 480W maximum Sensitivity Full-range, 91d B-SPL (1W, 1m) Horizontal beamwidth 120° Vertical beamwidth 100° Enclosure construction Mica-reinforced polyethylene copolymer structural foam Fusing Built-in 4-ampere quick-acting fuse (replaceable) Insert locations Four M8 (8 mm) Connectors Two (2) parallel-wired 1/4 " (6. 3 mm) phone jacks and two (2) parallel-wired male XLR connectors Dimensions 13 " (H) x 20 1/2 " (W) x 12 1/2" (D) (33 x 52 x 32 cm) Weight 31 lb (14 kg) Component Description Each 802 Series II loudspeaker uses eight 4 1/2" full-range drivers mounted in symmetric vertical pairs on a faceted Articulated Array ® baffle assembly.

Made in Germany Serial No. : ® Figure 1 Beamwidth vs Frequency (Bose 802-II) The loudspeaker shall be provided with a ducted vent system, tuned at 55Hz. The input connectors of the 802 Series II loudspeaker shall consist of two (2) parallel-wired 1/4 inch (6. 3 mm) phone jacks and two parallel-wired male XLR connectors. The loudspeaker enclosure of the 802 Series II loudspeaker shall be composed of mica-reinforced polyethylene copolymer structural foam. Outer dimensions of the 802 Series II loudspeaker shall be 13 " (H) x 20 1/2 " (W) x 12 1/2 " (D) (33 x 52 x 32 cm); its weight shall be 31 lb (14 kg). The loudspeaker shall be the Bose 802 Series II loudspeaker system. The loudspeaker system shall be supplied with a separate systems controller, to be connected before the input(s) of the system power amplifier(s). The fixed, 2-channel systems controller shall provide active electronic equalization and crossover functions. It shall include an operating mode switch, input sensitivity switch, low-frequency output level control, and mono sum switch. The systems controller shall use screwtype terminal strips for balanced input and output wiring connections. Outer dimensions of the systems controller shall be 1 3/4" (H) x 19. 0 " (W) x 8. 0 " (D) (4 x 48 x 20 cm). It shall fit in the single space of a standard 19 " equipment rack for mounting. The electronic controller shall be the Bose 802 C Series II systems controller.
