SM-U2 One-to-Two Wireless Microphone

SM-U2 One-to-Two Wireless Microphone

Featuring an independent module non-diverse design with a dedicated channel selection system, a single channel failure does not affect overall operation, enabling more convenient maintenance. Equipped with automatic frequency scanning and planning capabilities, it intelligently detects and avoids interfering channels while rapidly locking onto available frequencies. Combining digital frequency locking technology with PLL RF stabilization technology, it effectively isolates same-frequency/adjacent-frequency interference, ensuring pure audio quality, a wide dynamic range, and low-latency transmission that restores pristine original sound.

The system supports flexible combinations of handheld, lapel, and conference microphones to adapt to diverse scenarios: Handheld microphones feature 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 features a metal panel with a high-brightness IPS TFT display, while the aluminum alloy square microphone boom allows adjustable tilt angles, delivering a solid and premium overall feel. The newly designed high-contrast VA LCD display, paired with an intuitive user interface, provides clear visibility of key parameters. Support for quick settings and shortcut key operations significantly enhances the user experience, making it a reliable choice for professional performances, conferences, speeches, and similar scenarios.
