 DCS***0 Full Digital Conference System
Full digital conference system which is based on audio video conference transmission protocol of self-dependent innovation (AVCBus), achieve the function of meeting audio&video data receiving, processing,forwarding control supervisor of conference terminal.
Main unit adopts ARM Cortex A8 processor which dominant frequency up to 1GB, Linux3.2 OS and SQ Lite database， then it can manage or control terminal units(including chairman unit, delegate unit, interpreter unit etc) and in charge of external data interchange. System supports upgrade to adapt to multiple usage requirements.
Adopting *4BIT and maximum up to *6 sampling rate high performance multi-channel Codec, the system integrate with AVCBus, audio delay, only 2 millisecond delay for audio
Adopt **0M internet hand-hand connection, support maximum ***4 capacity. 

1.1 System Features
1)Adopt proprietary technology patent audio&video conferencing transport protocol, or AVCBus for short.
2)Adopt ARM Cortex A8 processor, Linux3.2 operating system, digital intelligence platform of SQLite database
3)adopt *4BIT, *6KHZ uncompressed stereo sampling, 2 millisecond delay, *0KHZ system frequency response, with fine and smooth, vigorous and clear CD grade sound quality, meet the requirement of high-level internationalized conference sound field
4)Support maximum 6 microphone to speak at the same time(include chairman unit), support send the origin to microphone to amplified sound, support using with simultaneous interpretation system.
5)Multiple conference modes
a)PPT: Turn on microphone by pressing key, turn off it when loosing the key.
b)FIFO: When the quantity of turned on microphones exceed the total, the microphone turned on last will make the microphone turned on first off, to make sure the quantity of turned on can not exceed the total. 
c)LIMIT: When the quantity of turned on microphone is up to the total, if turn on new delegate units, it will enter queue application (**6 can enter application status at the same time), microphone that make application first will turn on if others turned off.
6)Adopt **0M internet hand-in-hand connection, support maximum ***4 unit.
7)Support AVB protocol
8)Main unit has the function of centralized management microphone, achieve the management of sleep, wake up, parameter setting and speak.
9)Main controller has expansion slot, can expand to achieve intelligent video track, it doesn't need computer software and third-party device.
ACS****0M Digital Main Unit


Main Unit Feature
*LCD interface and electronic pulse knob make operation simple style 
*Has external audio , MIC IN, AUX IN, RECORD OUT and mixed audio OUTPUT, MIC IN and AUX IN can adjust the volume.
*Sampling is *4BIT, *6KHZ, 2 millisecond delay, frequency response of system is *0KHZ, exquisite, rich and clear CD acoustic, meet the need of high-level and international meeting room.
*System support maximum 6 microphone to speak in the same time (include chairman unit), support send the origin to microphone to amplified sound, support using with simultaneous interpretation system. 
*Multiple conference modes
PPT: Turn on microphone by pressing key, turn off it when loosing the key.
FIFO: When the quantity of turned on microphones exceed the total, the microphone turned on last will make the microphone turned on first off, to make sure the quantity of turned on can not exceed the total.
LIMIT: When the quantity of turned on microphone is up to the total, if turn on new delegate units, it will enter queue application (**6 can enter application status at the same time), microphone that make application first will turn on if others turned off.
*Conference main unit module can add the function module according to your need, like simultaneous interpretation system module.
*Main unit has the function of centralized management microphone, achieve the management of sleep, wake up, parameter setting and speak.
*With functions of protection loop nodes
*Main unit has expansion slot, SD an HD video-tracking expansion card can be optioned as required, has remote controller design for intelligent video-tracking, it doesn't need computer software and third-party device. When connect more than 2 cameras, system can output video-tracking signal and venue full view signal at the same time.
