TOA Electronics VX-3000 Digital Amplifier Module 210W@70V - VX-030D...
The TOA VX-030DA is a single-channel Class-D digital power amplifier module designed for use within the VX-3000 Series voice evacuation system. Delivering up to 300 W at 100 V (or 210 W at 70 V / 150 W at 50 V), it provides transformer-free constant-voltage output for direct connection to distributed speaker networks. The module's EN54-compliant design ensures suitability for life-safety installations to European fire alarm standards.
As a modular component, the VX-030DA slides into VX-3000 frame units (VX-3004F, VX-3008F, VX-3016F) and draws DC power from the VX-3000DS or VX-3150DS power supply. Class-D amplification minimizes heat generation and power consumption — a standby mode reduces consumption further during non-emergency periods. An accessible rear fuse and removable front dust filter simplify maintenance in installed systems.
Key Features
| Feature | Benefit |
|---|---|
| 300 W Class-D amplifier at 100 V | High-efficiency design reduces heat and energy consumption in continuous-duty systems |
| Selectable 50 / 70 / 100 V output | Adapts to different distributed speaker network voltages without a transformer |
| EN54-compliant design | Meets European fire alarm system standards for life-safety voice evacuation applications |
| Modular frame design | Easy removal and replacement without rewiring — minimizes maintenance downtime |
| Standby power mode | Reduces standby consumption during idle periods in large installations |
| Removable dust filter | Keeps internal components clean in demanding environments |
| 100 dB SNR (A-weighted) | Provides clean, high-intelligibility audio for emergency announcements |
| 82.8 mm wide modular construction | Compact profile minimizes rack footprint in multi-zone, multi-channel systems |
Typical Applications
The VX-030DA is deployed within the TOA VX-3000 voice evacuation platform for EN54-certified fire alarm and emergency PA systems in commercial buildings, hospitals, shopping centers, airports, transit stations, hotels, schools, and high-rise facilities where compliant life-safety audio is required. It is specified for multi-zone installations where independent zone control and high amplifier density are required in a single system frame.
