Product Introduction

This system is designed for local sound reinforcement needs. Composed of one CT20 Seamless Local Omnidirectional Audio Capture and Amplification System (Ceiling Microphone) paired with local sound reinforcement equipment, it forms a complete local audio capture and playback system. Equipped with built-in audio processing algorithms, the sound reinforcement system delivers clear and authentic sound quality without the need for additional audio processing devices, evenly diffusing sound throughout the entire room. Speakers do not need to carry any additional sound pickup equipment, and audiences can clearly hear the speaker from any position in the room. Additionally, speakers can conduct real-time interactions with remote counterparts via a remote interactive system.

Key Customer Benefits

High-Quality Experience

Adopting the latest voice processing technology, it enables 360° omnidirectional clear sound pickup.
