TOA / CM-2330AT

The TOA CM-2330AT is a ceiling-mounted speaker that allows you to select the optimal speaker panel (sold separately) for your installation environment. Installation is easy thanks to its spring-catch system, which simply requires hooking the panel into place. One-touch wiring is possible with the plug-in connector, allowing for through-wiring and branching. The ATT circuit, which allows for 5-step volume adjustment, uses a transformer, ensuring constant attenuation regardless of input, and virtually no attenuation during emergency broadcasts.
