The average sound pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment. The peak maximum acoustic output is the peak SPL possible with the maximum recommended amplifier power using musical program material. 2 Full bandwidth pink noise is applied to the 502C Systems Controller and amplified to a level at the speaker terminals corresponding to one Watt as referenced to the nominal impedance. The average sound pressure level (dB-SPL) is measured at 1 meter from the speaker in an anechoic environment. 3 Full bandwidth noise, meeting the International Electrotechnical Commission standard #268-5, is applied to the 502C Systems Controller and amplified to a voltage at the speaker terminals corresponding to the power handling of the speaker. The speaker must show no visible or measurable loss of performance after 100 hours of continuous testing. 4 International versions use XLR-type connectors. System Description The Bose® Panaray® Sound System is a fully modular system which represents significant advances in loudspeaker array, low frequency transducer, and system control technology. The basic Panaray system consists of two 502®A controlled arrays, one 502B Acoustimass® bass enclosure, and one 502C system controller, and provides up to 122dB peak SPL (at 1 meter, driven with maximum recommended amplifier power) over the 55Hz to 15kHz range. Extensive research has yielded new technology in array design which, using a proprietary arrangement of Bose 4.5 inch full range drivers, results in tightly controlled horizontal and vertical beamwidth, and extemely smooth bandto-band directivity. The system also features a new, compact low frequency enclosure using Bose-patented Acoustimass technology. The Panaray sound system is a highly aesthetic voice or music sound reinforcement system for permanent audio installations in theaters, auditoriums, churches, nightclubs, transportation facilities, and other places where people gather to be entertained, enlightened, or informed. Component Description The 502A Controlled Array is a mid-high frequency component of the Bose Panaray system. It features five newdesign 4.5" (11.4 cm) helical voice coil drivers in a slim, elegantly-designed enclosure. The result is natural sounding, extremely even coverage at all frequencies over the entire listening area. It can be used either with the 502B Acoustimass bass enclosure for full frequency sound reinforcement, or separately for voice-only reinforcement systems. The Beamwidth* (-6 dB point) 300° 200° nominal horizontal 100° 80° nominal vertical 60° 40° 30° 20° 10° 100 500 1,000 5,000 Beamwidth* vs. Frequency of 502A Controlled Array 10,000 Frequency [Hz] * Beamwidth is the -6dB point, in each one-third octave band, on a polor plot representing the average within ten degrees of the horizontal and vertical planes about the array. 502A array is designed for installability in a variety of configurations, using its integral 10x safety-rated attachment points and Bose suspension and mounting accessories. The baffle and rear panel are constructed of high strength structural foam, and the speaker grille is constructed of a durable perforated steel. It is available in both Professional Gray and Arctic White, and both the enclosure and grille are fully paintable to match interior decor. The 502B Acoustimass bass enclosure uses a single high power handling, high reliability 12" (30 cm) woofer. This new Bose-designed low frequency transducer features a high temperature 4" (10.2 cm) voice coil, cast aluminum basket, and a high durablility rubber surround. The 502B provides clear, deep bass reinforcement from a small enclosure, as a result of Bose-patented Acoustimass speaker technology. Its low crossover frequency results in a non-localizable sound source, which allows it to be unobtrusively installed apart from the 502A arrays. The enclosure is fitted with 10x safety-rated attachment points (top and bottom) for mounting in a variety of orientations. Two-point suspension is easy to accomplish using the Bose CSB-5B suspension bracket. The 502B is available in both Professional Gray and Arctic White, and is covered with a scratch resistant vinyl, which can be painted to match any decor. The 502C systems controller is a single rack space device which provides cross-over functions, active electronic equalization, and dual channel signal processing for both the 502A and 502B. It features -10/+4dB-V input sensitivity switches, all-balanced inputs and outputs, -18/+3dB bass level control, bass mono sum switch, automatic output muting on turn-off, and a secure, rear-panel operating mode switch. An optional plug-in card is available for the 502C which allows 502A controlled arrays to be combined in a sound system design with the Bose Acoustic Wave® Cannon system. The Panaray system includes a complete line of accessories for suspending or mounting both the 502A and 502B in a wide variety of configurations. 100 Directivity (Q)* 10 1 100 500 1,000 Directivity vs. Frequency of 502A Controlled Array 5,000 10,000 Frequency [Hz] * Directivity is the ratio, in each one-third octave band, of the average response in the nominal 120º x 70º polar window, to the average response over the entire solid angle about the source. System Configurations The Bose® Panaray® system provides a flexible, building-block approach to fit the sound reinforcement requirements of many types of applications, from night clubs to cathedrals. Detailed installation and system design guidelines for the Panaray System are provided in the Panaray System Owner's Guide. For illustrative purposes, here are some typical system configurations. Figure 1 shows a block diagram of the basic Panaray System, consisting of one 502®B, two 502A's, one 502C, and three channels of amplication for a stereo system. This system provides 115dB SPL @ 1 m average acoustic output. Additional low frequency output can easily be achieved by locating the cabinet against large hard surfaces. (There is also bass volume adjustment possible through the rear-panel control on the 502C). Figure 2 illustrates how components can be added to the basic Panaray system to achieve a variety of SPL or coverage requirements. One example of an expanded system would be a small disco dance area. In this application, four arrays at the outer corners of the dance floor, plus two 502B's on the floor adjacent to the dance area, will deliver approximately 118dB SPL average, with 130dB SPL peaks, all components driven at maximum recommended amplifier power. Figure 3 shows how the Panaray components can be interconnected for a voiceonly paging system. This system is ideal for applications where voice reinforcement is needed over a large area, such as an airport terminal or a train station. Through the use of the Bose CVT-5 constant voltage transformer, multiple 502A's can be installed in a 70/100V constant voltage distributed system. (This system operates from 130Hz and above only, and is not recommended for use where music is an integral part of the program material). . . . .. .. .. . . .
