We help the world since 2012
Product Overview
Our high-performance audio transformers are engineered for crystal-clear signal transmission in demanding environments, including public address systems, indoor/outdoor sound columns, and commercial speaker installations.
Key Competitive Advantages
✅ Superior Frequency Response
80Hz–15kHz (±1dB) – ideal for voice clarity and music reproduction.
✅ Dual Input Flexibility
- 2-Wire: 0V–100V (Black-Red)
- 3-Wire: 0V–70V–100V (Black-Yellow-Red)
✅ Industrial-Grade Durability
- Epoxy resin encapsulation withstands humidity up to 95% RH non-condensing.
- Vibration resistance tested to 5G acceleration(MIL-STD-810G).
✅ Plug-and-Play Integration
Pre-drilled mounting holes and color-coded terminals simplify installation.
