Functional characteristics
1. The system adopts DSP/DDOV digital processing and transmission technology, 3.5-inch TFT display screen and five-dimensional navigation control button, with Chinese and English menus;
2. With 3 unit output, each can connect 25 conference speaking units, a single host can connect 75 conference units, (according to the power of the unit to determine the number of connections);
3. 48KHz audio sampling frequency, frequency response up to 40Hz-20KHz;
4. With two RS-232 interfaces, programmable central control system for control; Supports SONY VISCA, PELCO-D/P, B01 protocols and RS-485/RS-232 controls
5. Automatic ID addressing, can be customized number, boot automatic detection of the host and unit online, real-time monitoring of system operation;
6. The system has intelligent automatic protection technology, which can quickly locate the failure of the system when the non-power failure occurs in the conference host, and does not affect the operation of other equipment, which can ensure that the conference audio signal is not interrupted;
7. With one NET interface, support conference display connection, display content can be customized;
8. Built-in adaptive feedback suppression (AFC), environmental noise cancellation (AEC), digital equalizer (EQ), automatic gain control (AGC) function;
9.★ Built-in equalizer, can adjust the system output signal;
10. With the number of restrictions, first in first out, speech application, voice activated four working modes, the number of speakers can be set to 1 to 6;
11.★ With voice incentive function, the speaker automatically opens the microphone, and automatically closes when the speech is not detected;
12.★ The host and the computer use TCP/IP connection, the conference host control interface can be viewed and controlled through Android phones or tablets.
13. With 1 group of cannon and 2 groups of RCA audio input interface, you can input background music, wireless microphone, capacitor microphone, alarm signal, etc.;
14. With 1 group of cannon and 2 groups of RCA audio output interface, can be connected to sound reinforcement system, recording system, remote video conference system, etc.;
