      A/V AUTO SELECTOR SWITCHER (MAS-201AV)
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.
