The Vocia® VA-4300CV is a digital networked four-channel amplifier for use in Vocia systems. It is capable of delivering 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.
Four channels of 300W per channel • Flexible line monitoring • Page active relay • Comprehensive failover • Extended audio delay • Dual Ethernet ports for redundancy • Dual power inputs (100-240V AC and 48V DC) • CobraNet audio/control with dynamic use of available bundles • Rack mountable (2RU) • DSP functionality includes: BGM, regular and emergency paging, emergency messages and ANC support • CE marked and RoHS compliant • Covered by Biamp System’s 5-year warranty
