• Name：3G-SDI Master-Slave Switcher Splitter
  
  This device could be Master-slave Swicher or 1 to 8 SDI Splitter. it could support 3G-SDI, HD-SDI, SD-SDI, ASI signal. Broadcast quality, could be a 1+1 back up SDI Switcher and splitter, it could be use by train for PIS systerm transmission 
  
  Introduction
  
  1. The device includes 2-ch SDI input, 2-ch SDI loopout, 8-ch SDI output, 1-ch analog audio(unbalanced) output. SDI loop channel 1 comes from SDI input channel 1,  SDI loop channel 2 comes from SDI input channel 2.
  2. Two SDI input channels support master-slave switch function, SDI 1 is master input channel, SDI 2 is slave input channel. SDI 1 signal will be distributed to 8 SDI output channels, and meanwhile audio will be decoded to audio output port.
      When this device detect that the SDI 1 resource has no input, the slave channel of SDI 2 will start work to make sure the whole system keeps working in good status. If SDI 1 and SDI 2 resources both has no input, the device will keep one frozen picture and no audio output. The frozen picture could be designed according to user’s request.
  3. The device supports SDI (1080P60/50Hz,1080i 60/50/30Hz ,720p 60/50Hz,SDI 576i )
  4. All SDI output channels will keep the same quality as SDI input resource
  5. Support cascade transmission, using 9 pcs of such switcher could have 72 channels SDI output( the following diagram is for reference)
  6.  All external connectors of the equipment is fastened connectors.
  7. Meet electromagnetic compatibility
  8. DC12V power supply
