Vocia VO-4e

The Vocia VO-4e is an enhanced networked audio output expansion device that allows the user to add four line-level and CobraNet® output channels to be added to a Vocia system. The VO-4e can be configured for channel-to-channel or device-to-device failover and uses comprehensive fixed-chain digital-signal processing within the device, including volume control, ducking, equalization, compressor/limiter, speaker crossover, delay, and output gain. Emergency messages for life-safety systems are stored in non-volatile memory. Two RJ45 connectors on the rear of the device provide redundant connectivity to process control data, audio and power over an Ethernet cable. In addition to this the VO-4e also has dual inputs for accepting power from an Auxiliary supply. The per-channel paging relay provides a contact closure when Paging is active on an associated channel.
