Powerful 4-Channel 300W Constant Voltage Amplifier
The Vocia VA-4300CV is a four-channel digital networked amplifier designed for use in Vocia systems, delivering 300 watts per channel with robust failover capabilities and extensive DSP functionality. This CobraNet-enabled amplifier supports emergency paging, background music, and ambient noise compensation, making it an essential component for public address and mass notification applications. With EN 54-16 certification, it meets stringent safety and compliance standards for life safety systems.
CobraNet-Enabled for Seamless Network Integration
Equipped with CobraNet audio and control functionality, the VA-4300CV provides dynamic use of available bundles for efficient audio distribution. Dual RJ-45 connectors ensure redundant network connectivity, maintaining audio performance even in the event of a network failure. As part of the Vocia platform, this amplifier integrates seamlessly with paging stations, message servers, and emergency interfaces.
Comprehensive Failover and Reliability Features
Designed for mission-critical applications, the VA-4300CV offers multiple failover mechanisms, including device-to-device and channel-to-channel redundancy. This ensures continued operation during power or network failures. The page active relay outputs provide a contact closure per channel when paging is in use, reinforcing its role in emergency communication systems.
Advanced Digital Signal Processing for Optimized Audio
The onboard DSP provides a fixed-chain signal processing architecture, allowing the VA-4300CV to manage background music, standard and emergency paging, and stored emergency messages. It also supports ambient noise compensation (ANC) for consistent audio clarity, automatically adjusting output levels based on environmental noise conditions.
Flexible Power and Output Options for Any Installation
The VA-4300CV supports both AC (100-240V) and dual 48V DC power inputs, ensuring continuous operation even during power interruptions. Its transformer-coupled outputs allow operation with low impedance (4Ω, 8Ω) or constant voltage (70V, 100V) speaker systems. Flexible line monitoring and extended audio delay of up to 32 seconds per channel enhance its adaptability to complex audio installations.
TAA Compliance for Government and Enterprise Installations
Complying with the United States Trade Agreement Act (TAA), the VA-4300CV is approved for federal procurement and enterprise-scale installations. With its robust design, networking capabilities, and failover redundancy, it is the ideal amplifier for large venues, public transportation hubs, educational institutions, and emergency communication systems.
