Wireless digital conference host HA-310M, wireless discussion conference system host (2U with USB recording)

Wireless digital conference host HA-310M, technical features

1. Using digital technology as the core, built-in high-performance CPU, supporting discussion function

2. The main panel adopts spray coating technology, with a novel and high-end appearance design that highlights a high-tech sense

3. Using FM frequency modulation to transmit audio, combined with high fidelity restoration circuit and anti howling device design, coupled with the use of a new anti howling single directional high-sensitivity capacitive microphone core, to achieve high fidelity restoration of conference sound quality

4. New concept of anti electromagnetic interference circuit design to eliminate electromagnetic interference from electronic products such as mobile phones

5. Wireless high-frequency signal communication is used for both control and audio signals, avoiding the need for microphone cables. Installation is simple, convenient, and flexible

6. High definition COG display, clear Chinese menu, easy to operate

7. Supports USB recording and high fidelity WAV format output

8. The host has 20 fixed frequency channels, which can use multiple wireless systems in the same location and avoid mutual interference with other wireless products in the venue.

9. Each system can support 200 microphones, and the number of speakers can be set to 1-4, with a maximum support of 4 chairpersons speaking simultaneously.

10. The system host is based on a stable and reliable PLL phase-locked loop circuit, wireless transmission digital control circuit, and analog audio transmission. The host can be set with first in first out and chairman specific speaking functions.

11. Digital control technology, the microphone only occupies 4 audio frequency points to avoid the occurrence of cross frequency phenomenon. Solved the problem of traditional one to four UHF wireless conference not being able to use multiple wireless conference microphones in the same contract.

12. The effective communication distance of RF is 60 meters indoors and 100 meters outdoors.
