Introduction
About the MPS Series
The Extron MPS 112 and MPS 112CS are media presentation switchers featuring
three A/V switchers and a program audio switcher with microphone pre-amplifier
and mute controls in one product. The A/V switchers include a four input, one
output VGA/audio switcher; a four input, one output S-video/audio switcher; and
a four input, one output composite video/audio switcher. The MPS 112 and
MPS 112CS accept microphone input and mix the microphone signal with the main
audio in "talk-over" mode. Both models have an RS-232 control port. The MPS
112CS also features switchable 48 V phantom power for the microphone.
The MPS Series is a one box solution for small presentation systems.
Throughout this manual both models of this switcher are referred to as "MPS" or
"MPS 112" if the instructions are not model-specific.
