Biamp Vocia VA-4300CV Networked Four-channel Amplifier - 911.0417.900
Product Overview
The Vocia VA-4300CV is a networked four-channel constant-voltage amplifier for paging, voice evacuation, and commercial install-sound systems. Delivering 300W per channel at 70V/100V, it is built for life-safety and distributed audio applications that require networked amplification with redundancy. As a CobraNet-enabled rack-mount amplifier it integrates into decentralized Vocia paging and EVAC networks.
Product Description
The VA-4300CV provides four channels of 300W continuous power with 70V/100V constant-voltage output. It is CobraNet-enabled for audio and control with dynamic bundle use, and includes dual Ethernet ports for redundant connectivity, dual power inputs (100-240V AC and 2x 48V DC), and comprehensive device-to-device and channel-to-channel failover. A page active relay, extended audio delay of up to 32 seconds per channel, and flexible line monitoring support reliable distributed paging. The 2RU chassis is EN 54-16 certified, CE marked, and RoHS compliant.
Key Features
- Four channels at 300W — Each of the four channels delivers 300W continuous at 70V/100V for distributed loudspeaker lines.
- CobraNet networking — CobraNet audio and control with dynamic bundle use integrates the amplifier into a Vocia network.
- Comprehensive failover — Device-to-device and channel-to-channel failover maintain audio in mission-critical paging systems.
- Redundant connectivity — Dual Ethernet ports and dual power inputs provide network and power redundancy.
- EN 54-16 certified — EN 54-16 certification supports use in voice alarm and evacuation systems.
- Line monitoring — Flexible line monitoring and a page active relay support supervised distributed audio.
- Extended delay — Up to 32 seconds of audio delay per channel aids time-aligned distributed systems.
- Warranty — Covered by the Biamp 5-year warranty.
