The document describes the TOA BS-633A/633AT wall mount speaker systems. The BS-633A is a basic 5" cone speaker with a transformer allowing multiple power taps. The BS-633AT includes an additional built-in attenuator, allowing connection to 2-wire and 3-wire speaker systems. Both have a compact ABS resin enclosure and push-in terminal for easy installation. Key specifications include a frequency response of 120-15,000Hz, 91dB sensitivity, and multiple power taps for 100V and 70V speaker lines.

DESCRIPTION The BS-633A/AT are wall-mount 5" (12cm) cone-type speakers with a BS-633AT compact and unobtrusive enclosure of ABS resin. Installation is quick 173 (6.81”) 101 (3.98”) 120 (4.72”) and easy, and the speakers can be hook-mounted or mounted directly onto a wall. A push-type input terminal allows easy cable connections 184 (7.24”) 195 (7.68”) and bridge wiring. Input impedance can easily be adjusted by changing the tap position of the transformer. The BS-633AT comes with a built-in attenuator and can be connected to 2-wire and 3-wire systems. The speakers are highly cost-effective and well-suited for BGM and announcement applications. 81 (3.19”) 5 (0.2”) (0.45”) 12 11.5 (0.47”) FEATURES Fixing Hole • Compact and unobtrusive design Bridging terminal N • Quick and easy installation GRY R N BLK C • High cost-effectiveness Attenuator BLK 3.3kΩ RED 1.7kΩ N R COM • Ideally suited for BGM and announcements R 8Ω 3-wire connection WHT COM WHT N C R (Transformer connection when the speaker is supplied from the factory) C (Note) Use transformer terminals when changing input impedance.
