All signals going through the wall plate transmitter are sent digitally up to 450 feet.   "They are the perfect solution for integrating digital and analog sources via a single cable," says Crestron's director of marketing Vincent Bruno.  "DM wall plates give you remote input connectivity for virtually any AV source." The DM-TX-400-3G can install anywhere in the room and can be wall, floor or even lectern mounted using a standard triple-gang box.
