The Bose Panaray 502 system is a fully modular system that represents a major advance in speaker array, low-frequency transducer and system control technology. It consists of two 502A controlled array loudspeakers, one 502B Acoustimass woofer and one Panaray system controller, providing up to 122dB peak SPL (1m, driven with maximum recommended power) over the 55Hz to 15kHz range.
The Bose Panaray 502 series consists of the 502A controlled array speaker and the 502B Acoustimass low‑frequency enclosure. Both units are fully modular, feature Bose patented driver technology and are intended for permanent installation in venues such as theatres, churches and nightclubs.
The manual provides detailed technical data, recommended amplifier power, mechanical dimensions, mounting accessories and warranty information, as well as example system configurations for speech‑only and full‑range audio applications. This manual is written in Chinese.
