Introduction

The seamless sound amplification ceiling array microphone consists of 129 high fidelity microphones, designed with a composite circular array layout to provide the necessary pickup sampling conditions for the algorithm; The CPU adopts a professional audio processor (8-core, 6T high computing power) and is equipped with industry-leading audio signal processing algorithms, such as low latency ClearVoice AI algorithm, real-time feedback suppression engine, adaptive sound field control technology, multimodal AI noise reduction system, spatial sound field modeling technology, traditional audio processing+AI deep algorithm dual engine architecture, dynamic beamforming, etc., which can effectively improve the quality of voice amplification interaction; The design adopts a professional audio composite circular array layout microphone, which can achieve 17 amplification areas and 33 pickup areas, with a amplification distance of 4 meters and a pickup distance of 8 meters, effectively picking up sound from any position in the pickup area; Built in cascading function module, capable of cascading multiple seamless sound reinforcement ceiling array microphones; Built in Dante module to achieve network audio transmission function. Built in advanced algorithms that automatically match various scenes, whether it is the effect of local amplification or the effect of outputting to remote terminals, can achieve clear and high fidelity vocals.

Features

1. Wide sound pickup: The seamless sound amplification ceiling array microphone is composed of a 129 unit omnidirectional array microphone, with a sound amplification distance of 4 meters and a sound pickup distance of 8 meters, achieving true seamless soundamplification wherever you go.
2. High volume: The sound feedback gain is ≥ 15dB. With a higher volume, it is less likely to howl and makes speaking without burden.

3. Clean sound: Implant ClearVoice AI deep algorithm to accurately recognize sound, remove various noises, and enhance speech signals.
4. High flexibility: Supports custom setting of positioning pickup, supports 33 pickup zones and 17 amplification zone mode settings, and can support multiple cascaded adaptation to different scenarios.
5. Easy to expand: Rich analog and digital (Dante, USB) audio interfaces, can be used independently, and can be connected to wireless microphones, without the  need for additional audio processors;

6. Easy to manage: The system is simple and provides multiple external control methods such as infrared, 485, and network to meet different needs and make the system more flexible.
