Functions and characteristics
- Adopting DSP/DDOV digital processing and transmission technology, it conforms to IEC60914 international standard, GBT15381-94 and GB50799-2012 national standard;
- Equipped with 3.5-inch TFT display screen and five-dimensional navigation control keys, with Chinese and English menus, can complete all the system settings without the computer, improve the installation and debugging efficiency;
- The original digital processing and transmission technology of DCP/MOVE, no matter how many devices are not disturbed, can overcome the attenuation problem of long-distance transmission, the transmission distance of six-core wire can reach 250 meters, and the transmission distance of network wire can reach 150 meters.
- The connection mode adopts 6-core DIN shielded cable or 2-meter over 6-type network cable, which can effectively avoid and prevent the electromagnetic interference of the line and ensure that the data will never be lost.
- It has 3 output units, each six-core interface can connect 25 conference speaking units, a single host computer can connect 75 conference units, a network cable can connect 15 conference speaking units, and a single host computer can connect 90 conference units (the number of connections can be determined according to the power of the unit);
- The frequency response can reach 20Hz-20KHz by using 48KHz audio sampling frequency.
- 2 RS-232 interfaces, programmable central control system for control;
- It has a variety of connection modes, such as linear, ring and T/10 connectors.
- Adopt ID addressing, can define the number, start up the machine to automatically check the host and unit online list, can monitor the system operation in real-time, at a glance;
- With intelligent automatic protection technology, the conference audio signal can be guaranteed not to be interrupted in the event of non-power failure of the conference host.
- Built-in multi-channel internal communication and conference service functions, supporting the conference unit to send tea, paper and pens, waiters and other needs notifications;
- NET interface is provided to support conference display connection, and the display content can be customized;
- Supports rapid positioning of system failures without affecting the operation of other equipment;
- Has the short message function, may carry on the internal communication with other units;
- Built-in adaptive feedback suppression (AFC), environmental noise cancellation (AEC), digital equalizer (EQ), automatic gain control (AGC) functions;
- Built-in equalizer, can adjust the output signal of the system to meet the different occasions;
- 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.
