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.)

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 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 A can be mounted on a rack shelf, under a desk or podium, or on a projector pole, with an optional mounting kit.
