The M702 Cascade Microphone is a USB microphone that supports PoE Cascade, enabling flexible huddle and mid-sized conference room settings. Each M702 is built with an internal mic array and supports blind beamforming. With the cascade array, they are specifically designed to pick up accurate human voices at a long distance and automatically reduce environmental noise.
Omnidirectional Pickup
Features a high SNR microphone array design, achieving 360° omnidirectional audio pickup.
Intelligent Audio Algorithms
Incorporates built-in intelligent audio algorithms such as automatic noise reduction, echo cancellation, automatic gain, etc
PoE
Each microphone can be cascaded by Power over Ethernet (PoE).
Six Mic Cascaded
The M702 can cascade six microphones at the same time with a pickup range of a maximum area of 150㎡.
Blind Beamforming
The M702 achieves accurate positioning and adapts to the environment.
Flexible Installation
Support multiple installation methods such as desktop and lifting, flexible and fast deployment, and reduce operation and maintenance costs.
