About the SWP123 Presentation Switcher

The Extron SWP123 is a presentation switcher featuring three independent
audio/video (A/V) switchers and a master audio switcher in one enclosure.
They include a 4 x 1 composite video/stereo audio switcher, a 4 x 1 S-video/
stereo audio switcher, a 4 x 1 VGA/audio switcher, and a 3 x 1 Master Audio
switcher. The SWP123 accepts microphone input and mixes the microphone
signal with the main audio in "talk over" mode. The SWP123 also features a
built-in transcoder loop function and an RS-232/RS-422/RS-485 control port.
