The MCTWA provides immunity from false call-ins and its common return wiring eliminates the need for isolated speaker shields. Each MCTWA adapter provides 24-station operation.The adapter(s) are easily installed using plug-in centerline connectors. Each adapter is capable of handling up to 10 watts of audio power per channel. Each adapter operates from 24V DC at no more than 2.4 watts.
