ZHC-AI30 AI-Powered Noise Suppression Conference Central Host | GZZHYUN
ZHC-AI30 AI-Powered Noise Suppression Conference Central Host
Specifications：
1. Pioneering multi-integrated IoT conference technology that unifies digital wired and wireless conference systems, complying with the international standard IEC60914.
2. It supports 44.1kHz and 48kHz audio sampling rates, with no degradation of sound quality even for long-distance signal transmission.
3. The host can establish wireless control connections with computers through TCP/IP or Wi-Fi access.
The host supports IP address assignment to realize distributed deployment and unified management.
4. Equipped with AI intelligent automatic noise reduction technology.
The deep ambient noise suppression reaches 25dB, and the relative gain of adaptive feedback suppression hits 18dB.
Built with a deep learning model for the AI adaptive noise reduction algorithm, it can automatically distinguish valid audio including human voice and instrumental sound from ambient noise (steady-state noise and transient noise).
It features AI intelligent feedback suppression (5 adjustable switchable levels) and noise reduction function (switchable with 5 adjustable strength levels) to meet the needs of different conference scenarios. No obvious audio distortion or pumping effect occurs after noise reduction.
5. Built-in Dante/AES67 network audio interfaces, compatible with all Dante/AES67 audio devices.
Users can adjust all parameter values remotely via PC host software and iPad software under TCP/IP connection.
6. It supports PoE Ethernet power supply, digital signal transmission and DSP control, all transmitted via a single cable.
The system units adopt ring loop wiring (1 output plus 1 backup input) to guarantee efficient and stable operation of the whole system.
The system boasts high stability and supports cable hot swapping, allowing users to add microphones to the system anytime.
Users can set automatic tracking for multiple cameras via PC software, and preset panoramic positions are supported.
7. The main unit supports dual backup output of analog and digital signals, as well as dual backup power supply consisting of PoE power supply and AC220V power supply.
An optional external 4-inch wall-mounted touch control panel is available for managing and configuring the conference host conveniently. It can display the following information:
a. Four optional speech modes: Normal Mode, FIFO Mode, Free Speech Mode, Request Mode
b. Speech quantity limit function: the maximum number of active speaking units can be adjusted to 1, 2, 4 or 6; chairman units and VIP units are free of this limit
c. Adjustable system volume, treble and bass
d. Configuration selection: switch to the setting interface of wireless conference system, and set parameters for wired conference system and wireless conference system separately
When connected to a computer and matched with the system control software, more functions are available:
a. Centralized microphone management, including microphone pickup gain adjustment, forced mute/unmute and speaker information registration
b. Support conference check-in and voting functions
c. Interact with microphones to receive service requests such as water, pens and paper
d. Check the online status of each microphone
e. VIP units can be set via software; the activation of VIP units will not be restricted by the upper limit of open conference units or speech modes
8. The multi-integrated wired & wireless IoT conference technology enables unified software management and parameter configuration for both digital wired conference system and wireless conference system.
The integrated conference technology also allows splitting the whole system into independent wired or wireless subsystems for separate use.
