Introduction
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.
“SWP123” and “switcher” are used interchangeably in this manual to refer to
the SWP123 Presentation Switcher.
SWP123 Switcher Features
Bandwidth — Bandwidth for the VGA switcher is 450 MHz (-3dB), allowing the
switcher to switch everything from NTSC video to high-resolution computer
displays.
Multiple video inputs — Twelve inputs can include four composite video (NTSC,
PAL, or SECAM) on BNC female connectors, four VGA (or SVGA, UXGA,
RGBHV, RGBS, RGsB, or RsGsBs) on 15-pin HD female connectors, and four
S-video (NTSC, PAL, or SECAM) on 4-pin mini DIN female connectors.
Multiple video outputs — Three outputs for simultaneous (in Separate mode), and
one at a time (in Single mode) display on VGA, S-video, or composite video.
Multiple audio inputs — Twelve line level unbalanced stereo inputs can include
four to the VGA group, four to the S-video group, and four to the composite
video group. All audio inputs are on female RCA connectors.
Multiple audio outputs — One output for each group (VGA, S-video, and
composite video), plus Master Audio. All audio outputs are balanced or
unbalanced on 3.8 mm, 5-pin captive screw connectors.
Master audio switcher — A 3 x 1 stereo audio switching system allows the audio
input of any video group to be selected for Master Audio output, with
volume and mute control.
Individual input audio attenuation adjustments — To balance each audio input
Master-Audio-Follow-Video switching — When enabled, the Master Audio
automatically follows the last input selected, regardless of group (VGA,
S-video, or composite video).
This feature is disabled as a factory default. You must enable the feature
using an RS-232 serial command or the ICS100 Control Software.
Decoder loop function — Converts all composite video signals to S-video using
an optional external composite video to S-video decoder.
This feature is disabled as a factory default. You must enable the feature using
an RS-232 serial command or the ICS100 Control Software.
Microphone input — Built-in microphone amplifier and Microphone Talk Over
button, with adjustable talk-over threshold control and microphone
volume level control
+24V Phantom power — For condenser microphones
Front panel control disable — Locks out all front panel functions except input
selection. When the front panel controls are disabled, all controls are still
available through RS-232, RS-422, or RS-485 commands.
