DATA SHEET: TOA VX-3004F AMQ VOICE ALARM SYSTEM FRAME
The VX-3004F AMQ is a high-performance, network-based voice evacuation and public address system manager belonging to the certified TOA VX-3000 series. Designed to consolidate reliable emergency broadcasting and multi-zone audio routing, this frame supports up to 4 output channels for highly reliable A/B speaker line configurations.
KEY FEATURES & SYSTEM ARCHITECTURE
Integrated DSP Functionality: Comprehensive acoustic controls including a parametric equalizer, high/low pass filters, feedback suppressors, compressors, and audio delay up to 2.7 seconds per channel.
A/B Speaker Line Redundancy: Provides 4 speaker output channels utilizing independent A and B line routing to ensure full compliance and continuous operation during a single-line fault.
Flexible Amplifier Management: Accommodates up to 4 hot-swappable digital amplifier modules. Configurable as 4 dedicated zones or 3 zones plus 1 shared standby amplifier.
Ambient Noise Control (ANC): Smart adjustment of output volume based on real-time room noise levels without interference from the system’s own audio broadcast.
