About the 4100-1327
Flex-50 digital-input audio amplifier for 4100ES emergency voice systems, 70.7 VRMS output and 50 W total. It is a dual-channel, self-backup design with three on-board Class B audio NACs. A digital decoder module selects one or two of the up to eight input channels carried on one twisted wire pair.
Digital amplifiers work only in digital audio systems; a system is either analog or digital, not intermixed.
