SilverCrest SHU 3.1 A1 HDMI switch
English - 7
Introduction
Thank you for purchasing the SilverCrest HDMI switch. The HDMI
switch communicates the HD signals of the connected source
devices (e.g. satellite receiver, Blu-ray/DVD player or HD camera)
to an output device (e.g. TV or digital projector). You can therefore
run three source devices on one HDMI port of your output device.
The HDMI switch cannot be used to distribute one source device
among three output devices, as only one output device can be
connected.
