TOA / CM-2330AT

The TOA CM-2330AT is a ceiling-mounted speaker that allows you to select the speaker panel (sold separately) that best suits your installation environment. The spring-catch system allows for easy installation by simply hooking the panel. The plug-in connector allows for one-touch wiring, allowing for both forward and branch wiring. The ATT circuit, which allows for volume adjustment in five stages, uses a transformer, so the attenuation is constant regardless of input, with almost no attenuation during emergency broadcasts.
