About this Manual

This manual contains information about the Extron YCS SW2 Switcher, and discusses how to install, configure, and operate it.

The terms “YCS SW2,” “YCS,” and “Switcher” are used interchangeably throughout this manual.

About the YCS SW2

The Extron YCS SW2 is a high-performance, two input (one composite video and one S-video) switcher with three simultaneous outputs (one composite video and two S-video), digital transcoding and autoswitching capabilities, and digital time base correction (TBC). 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.

Certain projectors have both video and S-video inputs, but can use only one of them at a time. The YCS SW2 solves this problem by autoswitching between composite video and S-video, then decoding the S-video to feed to the projector. (See figure 1-1 under Application Diagrams, later in this chapter.)

The YCS SW2 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.)

Inputs can be selected by pressing the front panel buttons, by enabling autoswitching using a jumper wire, or by contact closure using a remote push-button device.

Features

Autoswitching — The YCS SW2 can be configured to automatically switch to the active input when the YCS detects a video 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 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.

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 two S-video outputs allow for recording and display at the same time.

Individually buffered S-video outputs — Two individually buffered S-video outputs are provided on one female 4-pin mini DIN connector and a pair of female BNC connectors, for easy integration.

Contact closure remote control — Inputs can be selected remotely using a user-supplied two-button contact closure device.

Quad standard compatibility — The digital quad standard decoder/encoder provides for universal compatibility.

Enclosure — The YCS SW2 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 supply — 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 can be mounted on a rack shelf, under a desk or podium, or on a projector pole, with an optional mounting kit.
