Extron VSW 2VGA A - это компактный и бюджетный активный коммутатор VGA и стерео аудио с двумя входами и одним выходом. Он позволяет пользователю переключаться между двумя источниками VGA сигнала с аудио и напрявлять его на устройство отображения, например, монитор или проектор. Кроме того, VSW 2VGA A имеет буферизованный выход на монитор. Несколько коммутаторов VSW 2VGA A можно последовательно подключать друг к другу с помощью высококачественных VGA-кабелей Extron для создания многопользовательской системы презентаций.
