SM-U400F One-to-Four True Wireless Microphone System

SM-U400F One-to-Four True Wireless Microphone System

The core of the professional wireless microphone system features an independent module true diversity receiver and an independent channel selection system, minimizing frequency dropout risks at the hardware level to ensure stable and reliable transmission throughout. Leveraging automatic frequency scanning and intelligent planning, it detects environmental interference in real time and rapidly locks onto available channels. Combined with digital frequency locking technology and PLL RF stabilization, it completely isolates co-channel/adjacent-channel crosstalk interference. Paired with low-latency transmission, transparent frequency response, and a wide dynamic range, it accurately restores pure, authentic sound quality.

The system supports flexible combinations of handheld, lapel, and conference microphones, adapting to diverse professional scenarios: The handheld microphone features a Type-C charging port (compatible with AA 1.5V NiMH rechargeable batteries, sold separately). The conference microphone incorporates a built-in lithium battery and Type-C charging port. Its base employs a metal panel with a high-brightness IPS TFT display, while the aluminum alloy square microphone boom allows adjustable tilt angles, delivering a premium, sophisticated design. The receiver boasts a high-contrast VA LCD display with an intuitive interface and dedicated shortcut keys for critical functions. Key parameters are clearly visible, enabling efficient and convenient setup. This delivers a high-quality, highly stable audio solution for professional performances, large conferences, high-end speeches, and similar scenarios.
