Wired digital conference unit (Chairman) HA-631C, fully digital wired pure discussion tracking touch conference system Chairman unit (2.4IPS TFT display screen+touch switch) (8-core interface unit with T-wire) (network interface unit with 2-meter shielded Ethernet cable) Dual backup output

Technical features:

1. Compliant with international standards IEC60914 and GBT15381-94

2. ★ Metal panel design, overall high-end and solemn, in line with modern aesthetic standards

3. The unit is a passive device powered by the system host, with an input voltage of 24V, which is within the safe range

The unit with 8-core wire interface adopts T-shaped 8-core connection, and the wire adopts full line aluminum foil and water line shielding, greatly reducing the interference of strong electromagnetic waves on the wire

5. The unit of the Ethernet interface adopts a Category 6A Ethernet cable and a "hand-in-hand" cable connection method

6. Professional high fidelity capacitor microphone core, sensitive pickup, clear voice, bandwidth up to 20Hz~20KHz

7. ★ Adopting die cast aluminum alloy multi diamond square microphone, connected to the microphone base through a fixed joint, adjustable pitch angle, overall stable, high-end and atmospheric

8. ★ Built in fully isolated main microphone and backup microphone, two audio signals are output simultaneously. When the system where the main microphone is located fails, it does not affect the output of the backup microphone, ensuring the smooth progress of the meeting

9. Adopting anti-interference circuit design can prevent interference from electronic products such as mobile phones

10. ★ The microphone head is equipped with a dual color speaking light ring. When the unit speaks, the light ring is always on in red, and when the unit applies to speak, the light ring is always on in green

11. ★ Sensitive touch switch, the pattern will always light up green when not in standby mode, and the pattern will always light up red when pressed

12. ★ 2.4-inch high brightness IPS TFT display screen, clear display content, can display unit parameters, date and time, speaking volume, monitoring volume, etc., clearly understand the current usage situation

13. ★ Microphone with speech timing function

14. The microphone unit is equipped with a headphone output port and a volume adjustment button, allowing users to freely choose the output mode and adjust the volume

15. Adopting a "hand-in-hand" connection method, supporting hot swapping, convenient for installation and maintenance

16. ★ The speaking unit can apply for services such as tea, paper and pen, and assistance

17. The chairman unit has the function of approving representatives' speech requests;

18. ★ The chairman unit is not limited by the number of speakers;

19. The chairman unit has the priority function of fully controlling the order of the meeting;

20. The connection position of the chairman unit is not limited;

21. A system can support the simultaneous use of multiple chairman units.
