The Vocia® VA-4300CV is a digital networked four-channel amplifier for use in Vocia systems. It is capable of delivering continuous audio power at 300 Watts per channel. The VA-4300CV is CobraNet® enabled for audio and control with dynamic use of bundles. Two RJ-45 connectors on the rear panel provide redundant CobraNet connectivity to the Vocia network. The onboard DSP provides comprehensive fixed-chain, digital signal processing within the device. In addition, emergency messages are stored in local non-volatile memory. Page active relay outputs provide a contact closure per channel when paging is active on the channel. The amplifier also has comprehensive failover capability with device-to-device and channel-to-channel failover.
