• Has the short message function, may carry on the internal communication with other units or the host;

• By using DSP/DDOV digital processing and transmission technology, the attenuation problem of long-distance transmission can be overcome, and the line distance can reach 250 meters.

• The connection mode adopts 6-core DIN shielded cable or 2-meter over 6-type network cable to effectively avoid and prevent electromagnetic interference of the line (optional, can transmit 64 languages at the same time to ensure that the data will never be lost), and the connection mode adopts 6-core DIN shielded cable or 2-meter over 6-type network cable to avoid and prevent electromagnetic interference of the line.

• (Optional, 4/8/12/16/20/32, up to 64 languages);

• The connecting cable can lead out from the bottom and the back, which can guarantee the moving position of the speaker and the neatness of the desktop.

• It has a variety of connection modes, such as linear, ring and T/10 connectors, for easy installation and maintenance;

• 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.

• The unit is passive equipment, the conference host provides 24V power, low power consumption design, a single can connect 25 conference units;

• Adopt digital strong anti-jamming technology to ensure that the equipment in the venue is not disturbed by mobile phone, Bluetooth, radio, WiFi and other signals;

• There are four working modes: quantity limit, first in first out, speech application and voice control start, and the number of speakers can be set to 1 to 6;

• 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 five-key voting function, supports key check-in and check-in function, and dynamically displays data.

• Designed with advanced electrostatic isolation technology, static electricity can be avoided even in dry environments and regions.

• The system has the function of auto-repairing and supports the hot-swap function of live line, which ensures the safety of the system.

• 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;

• The system can access 100 chairman units at the same time, can set up an executive chairman and several vice-chairmen, executive chairman has priority and control, 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.

• It has the function of restoring the factory value, and can initialize the audio adjustment to prevent the noise from being disturbed.
