Product Features
Seamless Sound Amplification
Liberates presenters from physical constraints, enabling unrestricted movement and spontaneous presentations without preparatory complexities.
One-Touch Mode Switching
Integrates long-range pickup, local amplification, and remote interaction. Includes infrared remote control for instant switching between remote collaboration and local amplification modes.
Core Audio Processing Technology
Employs deep learning noise reduction and intelligent echo cancellation, with features like smart denoising, ultra-low latency, and automatic gain control to ensure clarity in noisy environments.
Plug-and-Play
Equipped with USB 2.0 and 3.5mm audio interfaces for instant digital/analog dual-mode connectivity, eliminating the need for professional audio tuning.
Flexible Power Supply
Supports USB or PoE (Power over Ethernet) for adaptable deployment in diverse environments.
