SP-7U
Equipped with four high S/N beam forming microphones and two extension microphones
Support AI echo cancellation and noise reduction,impressive sound performance
Large voice pickup range can cover the demand of a large conferencing room.
4+2 Digital Array Microphone
Equipped with four high SNR omnidirectional Microphone array to locate the speaker’s direction and position. Built-in advanced audio algorithms can support AI echo cancellation and noise reduction,impressive sound performance, large voice pickup range can cover the demand of a large conferencing room.
AI Audio Noise Reduction Technology
Adopting multi microphone extraction technology with self positioning target speakers, it can shield common conference noise such as keyboard, mouse or table tapping, fan sound, etc. During full duplex calls, it can achieve dual talk without pressure and clear calls, allowing attendees to focus more on the conference content discussion.
Fashionable Business Appearance
All aluminum alloy box, metallic silver color scheme, highly textured, suitable for various business scenarios such as meeting rooms and offices.
AI Echo Cancellation System
Equipped with a new generation of traditional signal processing and deep learning echo cancellation system, using highly robust traditional signal processing algorithms and integrating the latest deep learning network (CrossNet). It achieves the effects of both echo cancellation, noise reduction, and ensuring speech quality.
Professional Design of Sound Chamber
High fidelity acoustics is used to design the sound chamber, and the tweeter and bass speaker units are matched, and professional sound effects are used to tune. When playing music as a desktop audio, the bass is thick, the tweeter is thorough, the voice is clear and natural, and the voice is more exquisite.
Plug and Play
Equipped with standard USB2.0 interface, compatible with Type-A/C connection, device plug and play, and compatible with various mainstream conference software.
