Desktop Meeting Unit DMS-302C/D

sketch：

1. The representative unit adopts the latest six core ARM Cortex-A53 chip and is also equipped with a multi-core neural distributed GPU acceleration processor to ensure stable and reliable acquisition and transmission of distributed transmission signals;
2. Support HD Sound digital audio and video transmission technology, sending and receiving 1024 audio channels simultaneously through a regular Ethernet cable;
3. Using the top-level ADC chip AK5392 with 24bti/192KHz, the dynamic range and signal-to-noise ratio achieve CD sound quality
4. Adopting multi-channel digital filter transmission technology to solve crosstalk, noise, distortion, and noise caused by mutual interference between units;
5. POE switches are directly powered and connected to the switch using standard Ethernet cables, making system setup simple and flexible.
6. Support partition sharing technology, one conference host supports 4-6 conference rooms;
7. Support speech discussion, camera positioning and tracking functions
8. Adopting a fully copper shielded design to resist mobile phone RF interference, it has super strong resistance to mobile phone, electromagnetic, and high-frequency interference.
9. Adopting intelligent neural distributed algorithm technology to completely eliminate the phenomenon of host crashes caused by multiple units turning on at the same time;
10. Adopting the IEEE1588 precision clock protocol for clock synchronization and zero delay transmission of audio and video signals.
11. Using uncompressed audio transmission, 48K sampling rate, providing clear and perfect speech
12. Adopting soft control buttons to effectively avoid mechanical button sound impact;
