1. Description 

■ This is analog auto switching device which enables to choose finer channel from
    main and two sub analog A/V signals. 

■ This is dual auto switching device (analog/digital) which enables to choose finer 
    channel from main and two sub SDI enbedded audio signals. 

■  Input singal has auto switching function regadless analog or digital. 

■  It enables to switch into manual by front pannel button. It switches into channel 
     #2 automatically in case there is no signal from chanel # 1. 

■ There is one supervisory remote control port. Front 3 color LED helps to view the 
     status of signal and operation. 

■ It does not need amplifier to prevent dropping a feature of vidoe sinals for main 
    output. Dual power composition enables to maintain output signal even power 
    supply is failed.
