www.sy.co.uk 2
The SY-MS121 and SY-MS121-AP are multi-format switchers with 4 HDMI inputs, 4 VGA inputs and 2
composite video inputs, 1 component video input and 1 S-video input. Each of these inputs are presented
to all the output video connectors simultaneously. The resolution of the outputs can be set to one of five
resolutions.
Each input type and source can have different resolutions, but the output resolution will always be the one
shown by the Resolution LEDs on the front panel. As such the input video signal may be up-scaled or
down-scaled as necessary, providing consistent output resolution as required.
This Presentation Switcher is well suited to a wide range of applications in AV industry, Digital Signage and
at home; particularly when multiple source resolutions and formats are in use.

Using the Presentation Switcher
Connect all the available video inputs present in the installation to the appropriate input connectors and, if
required, any analogue audio signals to the corresponding audio inputs. Note that the audio inputs in the
VIDEO INPUTS section are shared between inputs one and three and also between inputs two and four.
Connect the display devices to the outputs as required or use the HDBT output where the display is too far
for a standard cable run for either the HDMI or the VGA outputs. Note that both the SY-HDBT-70P-R and
the SY-HDBT-100-R receivers provide only HDMI output.
To select an input, start by pressing the button for the source type, HDMI, VGA or VIDEO, then press the
channel button you wish to display from that group.
The MIC and LINE audio inputs are sent to all the audio outputs simultaneously and their levels can be
individually controlled from the front panel buttons.
