TOA VX-030DA Digital Power Amplifier Module
Official Product Datasheet | Exclusively Distributed and Managed by SKYRS Pakistan
Product Overview
The TOA VX-030DA is a highly efficient, lightweight Class-D digital power amplifier module specifically engineered for seamless integration into the TOA VX-3000 Voice Alarm and Public Address System framework (compliant with European EN54 fire alarm standards). Its space-saving, transformerless design drastically optimizes power delivery while offering robust energy efficiency through an automated low-power standby mode.

VX-3000 Series Family Variants (Supported via SKYRS Ecosystem)
Depending on your localized zone power requirements within Pakistan, the VX-030DA forms a unified matrix alongside alternative output modules to scale your PA/VA network:
VX-015DA Variant: 150W Class-D digital amplifier module sharing an identical modular form factor.
VX-050DA Variant: 500W Class-D digital amplifier module for higher acoustic density zones.
Deployment and Physical Installation
The physical handling, slot placement, and frame integration are managed directly by certified engineers under standard safety layouts.
Chassis Integration: The module utilizes a hot-swappable toolless slide-in design. It slots cleanly into the rear bays of compatible TOA Voice Alarm System Frames (VX-3004F, VX-3008F, or VX-3016F).
Thermal & Clearance Rules: Modules must be seated firmly into designated alignment tracks to allow correct front-to-back ventilation. The integrated dust filter must remain unblocked.
Bus Interconnection: Low-voltage signal routing and module power are executed using the packed premium DA Control Link cables hooked into the host frame backplane.
System Configuration
Configuration protocols require certified network parameters to prevent zone impedance mismatching or faults.
Voltage Line Configuration: The local output voltage (50V, 70V, or 100V) must be carefully dialed using the physical toggle switch located on the rear panel of the module before initialization.
Software Provisioning: System mapping is handled via specialized PC software to register the amplifier within the network, define emergency trigger logic, assign priority routing, and configure standby parameters.
Impedance Calibration: Line surveillance parameters must be calibrated down to the minimum load impedance threshold (33 Ω at 100V line) to guarantee ongoing pilot-tone line monitoring.
