Quad standard compatibility — The digital quad standard 
decoder and encoder provide for universal compatibility.
Enclosure — The YCS 100 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. 
The power supply input has single diode polarity 
protection.
Rack, furniture, and projector mounting — The YCS 100 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 contains information about the Extron 
YCS 100 Transcoder, and discusses how to install, confi gure, and 
operate it. 
The terms “YCS 100,” “YCS,” and “transcoder” are used 
interchangeably throughout this manual.
About the YCS 100
The Extron YCS 100 Transcoder has a composite video to 
S-video (luminance [Y] and chrominance [C]) decoder and an 
S-video to composite video encoder in one product. The high 
performance digital decoder has a time base stabilizer that 
corrects the jitter from VCR signals. A 5-line adaptive comb 
fi lter performs the Y/C separation, virtually eliminating chroma 
noise. Each input has its own individually buffered loop-
through signal. 
The transcoder is compatible with NTSC 3.58, NTSC 4.43, 
SECAM, and PAL standards.
Features
Digital decoding and analog encoding — The YCS 100 digitally 
decodes (separates) the composite video input signal 
into Y and C for S-video. It provides analog encoding 
(combining) of the Y and C signals of S-video input into 
composite video. 
Time base stabilizer — The time base stabilizer (TBS) stabilizes 
the video signal in the time domain. This results in a 
signifi cantly 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.
Input connectors — The decoder has one composite video 
input on a female BNC connector. The decoder input 
is buffered and looped through, also on a female BNC 
connector.
    The encoder has one S-video input on 4-pin mini DIN 
connectors. The encoder input is buffered and looped 
through, also on a 4-pin mini DIN connector.
Output connectors — The decoder has one S-video output 
on a 4-pin mini DIN connector. The encoder has one 
composite video output on a BNC connector.
