Vocia VO-4e Enhanced Networked Audio Output Expansion Device

Description

Biamp Vocia VO-4e

The VO-4e is an enhanced networked audio output expansion device allowing the user to add four line-level and CobraNet output channels 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 RJ-45 connectors on the rear panel of the device provide redundant connectivity to process control data audio and power over a single Ethernet cable. 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.
