Functions and Features:
- Adopt all-digital conference technology, conform to IEC60914 international standard;
- A multi-functional conference terminal with speech discussion, video tracking, voting and conference services;
- Using 2.4 G digital frequency hopping (DSSS) modulation communication technology and ISM frequency band, voice data is exchanged through wireless transceiver to ensure that the audio delay is less than 5.5 mS;
- ISM frequency band. If the interference frequency system switches the high-quality frequency band automatically during the conference, it can coexist with WiFi completely and has strong anti-interference property.
- Supports simultaneous use of wireless and wired conferencing systems;
- Built-in conference service functions, supporting the conference unit to send tea, pen, waiter and other needs notification;
- Has the short message function, may carry on the internal communication with other units or the host;
- 128-bit AES Rijndael and 48-bit PIN encryption protection are adopted to prevent eavesdropping and unauthorized access and ensure the privacy of the meeting;
- The system adopts the method of ID addressing. The conference host or conference management software can customize the ID number of the unit and avoid the duplication of ID number.
- Super anti-jamming ability, incoming calls will never produce “Zizi” sound, to ensure that the equipment will not be disturbed by mobile phones, Bluetooth, radio, WiFi and other signals;
- Adopting detachable lithium battery with large capacity and low power consumption, it can speak continuously for 40 hours, and the waiting time can be up to 160 hours.
- There are four working modes: quantity limit, first in first out, speech application and voice control start, which can support four conference units to speak at the same time;
- It has the function of voice excitation, automatically turns on the microphone and turns off the microphone when no speech is detected.
- (optional time and timing of speech);
- With the camera, the speaker can be tracked automatically, and the screen freezing function is supported.
- It has the function of voting, supports the function of keystroke check-in and make-up check-in, and dynamically displays the data.
- Designed with advanced electrostatic isolation technology, static electricity can be avoided even in dry environments and regions.
- Electret super-heart-shaped directional microphone, with audio start-up function, to ensure sound pickup distance and sound quality, sound pickup distance up to 50cm;
- Supports 48K audio sampling frequency, frequency response up to 40Hz-20KHz, close to the CD sound quality effect;
- The microphone pole is provided with an indicator light ring, which can display the status information such as speaking, setting video, unnumbered ID, voting key prompt, etc.
- The microphone pole adopts spiral detachable design, which is convenient for equipment transportation, storage, installation, maintenance and storage between sessions.
- Built-in high-pass filter function to facilitate the removal of low-frequency components in the sound when needed;
- 256 unit or more than 256 chairman units can be access at that same time, an executive chairman and several vice chairmen can be arranged, the executive chairman has priority and control right, and the vice chairmen have priority;
- With DSP digital audio processing chip, each unit can be individually adjusted high and low tones;
- Stable capacitive sensing touch keys and glove mode support;
- Have 2 3.5 mm headphones, which can be used to monitor and record meetings, and the volume can be adjusted;
- It has the key function of correcting unit to ensure the sensitivity of touch key.
- With a Micro USB data interface, the device can be upgraded and maintained without disassembly, the battery can be charged with USB cable, and the unit can be used normally when charging with USB;
- It has the function of restoring the factory value, and can initialize the audio adjustment to prevent the noise from being disturbed.
