Yamaha ST-L1WA Indoor / Outdoor High-Impedance Transformer for VXL1, 70V, White

Deliver consistent, professional audio for paging, security and surveillance with the Yamaha ST-L1WA indoor/outdoor high-impedance transformer. Designed specifically for VXL1 speaker arrays, this 70V speaker transformer streamlines multi-speaker deployments—reducing amplifier channels and cabling complexity for large venues, campuses, and monitoring installations. The ST-L1WA’s IP55 weather-resistant rating protects audio distribution from dust and water exposure, making it suitable for exposed outdoor zones and perimeter security systems. With compatibility for VXL1-24/16/8 (-WR) models and a compact open-frame layout (approximately 11" x 8", 9.45 lb), installation into racks, enclosures, or speaker mounts is fast and unobtrusive. Yamaha’s engineering ensures stable impedance matching and clear voice annunciation across paging, alarm, and surveillance applications, improving intelligibility for operators and first responders. Ideal for integrators specifying equipment for security, monitoring, or commercial AV projects, the ST-L1WA delivers durable performance where reliable audio matters most. Add this transformer to your next security or surveillance audio design to simplify installation and enhance system resilience.
