Features
Autoswitching — The YCS SW2 A can be configured to
automatically switch to the active input when the YCS
detects a signal, thus providing hands-free switching.
If both the composite video and the S-video signals are
present, the switcher defaults to input 2, S-video.
Digital encoding and decoding — The YCS SW2 A digitally
decodes (separates) the composite video input signal into
Y and C for S-video, and encodes (combines) the Y and C
signals of S-video input into composite video.
Audio — The YCS SW2 A features a 2x1 switcher for unbalanced
stereo audio.
Digital time base correction — Time base correction stabilizes
the video signal in the time domain. This results in a
significantly more stable image on the screen and better
recording quality from input sources with unstable video
signals, such as consumer VCRs and worn or multi-
generation VHS tapes.
Simultaneous composite video and S-video outputs — One
composite video and one S-video output allow for
recording and display at the same time.
Contact closure remote control — Inputs can be selected
remotely with a user-supplied contact closure device.
Quad standard compatibility — The digital quad standard
decoder/encoder provides for universal compatibility.
Enclosure — The YCS SW2 A has a compact 1U high, ¼-rack
wide, 3 inches deep Versatools ® metal enclosure that can
be easily placed or mounted in a variety of locations.
Power suppl y — An external 12 VDC power supply with a
two-pin captive screw connector accepts 100 to 240 VAC.
Rack and furniture mounting — The YCS SW2 A can be
mounted on a rack shelf, under a desk or podium, or on a
projector pole, with an optional mounting kit.
About this Manual
This manual describes the Extron YCS SW2 A Switcher, and
discusses how to install, configure, and operate it.
The terms “YCS SW2 A,” “YCS,” and “Switcher” are used
interchangeably throughout this manual.
About the YCS SW2 A
The Extron YCS SW2 A is a high-performance, two input,
dual output video and audio switcher with transcoding and
autoswitching capabilities and digital time base correction
(TBC).
The YCS SW2 A has one composite video and one S-video input,
which can be switched and transcoded to output simultaneously
on a composite and an S-video output. Each input also has
an unbalanced stereo audio input switched to one unbalanced
stereo audio output.
Using a 3-line NTSC/5-line PAL digital comb filter, the YCS
accepts NTSC 3.58, NTSC 4.43, PAL, or SECAM composite
video, and decodes the signal into Y (luma) and C (chroma) for
S-video. As an encoder, it combines Y and C signals and outputs
a composite video image.
You can select inputs by pressing the front panel buttons, by
enabling autoswitching using a jumper wire, or by contact
closure using a remote push-button device.
Certain projectors have both video and S-video inputs, but
can use only one of them at a time. Because of this, they
usually share one audio input between them. The YCS SW2 A
solves this problem by allowing both an S-video source and a
composite video source, each with audio, to be connected to
this type of projector, and switch between them automatically.
The remaining video output can then be used for monitoring
or recording purposes. (See figure 1-1 under “Application
Diagrams,” later in this chapter.)
The YCS SW2 A can also be used at the output of a multi-format
switcher, such as the Extron MPS 112, to automatically select
between the video and S-video group outputs, sending a single
S-video signal to the projector. (See figure 1-2.)
