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.
