Full bandwidth pink noise is applied to the Panaray system digital controller and amplified to a level at the speaker terminals corresponding to the long-term rated power handling of the speaker. 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.

Full bandwidth pink noise is applied to the Panaray system digital 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.

Full bandwidth noise, meeting the International Electrotechnical Commission standard #268-5, is applied to the Panaray system digital 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.

International versions use XLR-type connectors.

System Description

The Bose® Panaray® 502® system is a fully modular system which represents significant advances in loudspeaker array, low-frequency transducer, and system control technology. Components of the basic Panaray 502 system, which are sold separately, include two 502 A controlled arrays, one 502 B Acoustimass® enclosure, and one Panaray system digital controller. This basic system 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 extremely smooth band-to-band directivity. The system also features a new, compact low-frequency enclosure using Bose-patented Acoustimass technology. The Panaray 502 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 502 A controlled array is a midto high-frequency component of the Panaray 502 system. It features five new-design 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.

*Beamwidth is the -6dB point, in each one-third octave band, on a polar plot representing the average within ten degrees of the horizontal and vertical planes about the array.

It can be used with either the 502 B Acoustimass enclosure for fullfrequency sound reinforcement, or separately for voice-only reinforcement systems.

The 502 A controlled array is designed for installation 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 décor.

The 502 B Acoustimass enclosure uses a single high-power-handling, high-reliability 12" (30 cm) woofer. This new Bose-designed lowfrequency transducer features a hightemperature, 4" (10.2 cm) voice coil, cast aluminum basket, and a highdurability rubber surround. The 502 B speaker provides clear, deep bass reinforcement from a small enclosure, using patented Bose Acoustimass speaker technology. Its low cross over frequency results in a non-

localizable sound source, which allows it to be unobtrusively installed apart from the 502 A 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 502 B is available in both Professional Gray and Arctic White, and is covered with a scratch-resistant vinyl, which can be painted to match any décor.

The Panaray system digital controller is a single rack-space device which provides crossover functions, active electronic equalization, and dual-channel signal processing for both the 502 A and 502 B.

An optional plug-in card is available for Bose amplifiers, which allows 502 A controlled arrays to be combined in a sound-system design with the Acoustic Wave Cannon™ system.

The Panaray 502 system includes a complete line of accessories for suspending or mounting both the 502 A and 502 B in a wide variety of configurations.

*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

Figure 1: Basic Panaray system

502 B

The Bose® Panaray® 502® system provides a flexible, building-block approach to fit the sound reinforcement requirements of many types of applications, from nightclubs to cathedrals. Detailed installation and system design guidelines for the Panaray 502 system are provided in the Panaray 502 System Owner’s Guide. For illustrative purposes, here are some typical system configurations:

Figure 1 shows a block diagram of the basic Panaray 502 system, consisting of one 502 B, two 502 A speakers, one Panaray system digital controller, and three channels of amplification 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.

Figure 2 illustrates how components can be added to the basic Panaray 502 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 502 Bs on the floor adjacent to the dance area, will deliver approximately 118dB-SPL average, with 130dB-SPL peaks, and all components driven at maximum recommended amplifier power.

Figure 3 shows how the Panaray 502 components can be interconnected for a voice-only 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 502 As 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.)
