Why Choose TELUNSHI T480S?
✅ 1. Balanced Power — Cost-Effective for Most Installations
The T480S delivers 80W×4 @4Ω or 160W×4 @2Ω — clean, reliable power for most mainstream 4-speaker systems, with bridging capability for a subwoofer. The sweet spot between performance and cost — ideal for bulk orders used in standard upgrade packages, increasing your margin per system.
✅ 2. Class AB Amplification — Warm, Natural Sound Quality
Class AB topology combines the fidelity of Class A with the efficiency of Class B. Rich midrange, natural vocals, and musical warmth. Audiophiles prefer Class AB for its engaging listening experience. Great sound builds customer loyalty and word-of-mouth for your shop.
✅ 3. Flexible Crossover & Bridging Options
- Independent HPF/LPF: CH1/2 and CH3/4 have separate high-pass (32-250Hz) and low-pass (20-250Hz) filters, plus OFF mode for full-range. Easy active crossover setup to protect speakers and optimize soundstage.
- Bridgeable Design: Bridge CH1/2 or CH3/4 for higher power to drive a subwoofer. One amp handles both full-range and subwoofer duties — saving the cost of a separate mono amplifier.
✅ 4. High-Fidelity Specs — Low Distortion, High SNR
With ≥90dB SNR and ≤0.04% THD, the background stays black and noise-free. Stable performance even under sustained high load. Higher customer satisfaction, fewer after-sale issues.
✅ 5. Factory Direct — Tour Welcome
We are based in Foshan, the heart of China’s car audio manufacturing industry. Our own factory integrates R&D and production. Global buyers are welcome to visit our facility to see our processes, quality control, and real inventory. No middlemen — transparent pricing, consistent quality.
