INTRODUCTION
The SN-4100 series switcher is a 4 input to 1 output high
resolution VGA switcher. The ‘A’ models include bal-anced
stereo audio switching with audio following video.
The SN-4100 is ideally suited for stand alone use or as
an upstream switcher for a stand alone scaler such as
the FSR MAS-3100 or a scaling switcher such as the
FSR Compass, Compass S2 or Omni Navigator. The SN-4100
could also be used to route 4 high resolution sig-nals
to a down converter such as the FSR MDC-MK1.
At 1 RU in height, and 1/2 rack wide, the SN-4100 is
easy to install and does not require an excessive
amount of space. All connections are on the back of
the unit using HD-15’s for VGA and 5 position plug-gable
Phoenix connectors for stereo balanced audio.
Control of the SN-4100 is available on the front panel
through 4, large, easy to see push buttons with an LED
that illuminates for the selected input. The SN-4100
also provides a contact closure interface, with lamp
feedback, for remote control or to interface to an AMX
or Crestron system.
As with all FSR products, the SN-4100 includes all of
the necessary accessories for use and installation. The
SN-4100 ships with a power supply, manual and a full
width rack mount kit with removable blank.
