Overview 

 

 

 

The Contemporary Research 232-STSi Stereo S-Video PAL Tuner is a versatile RS-232 controlled PAL TV tuner featuring 
high-

quality S-Video video and balanced A2/NICAM stereo audio output, switchable composite AV input, closed-

captioning and on-screen text, 125 Channel Preset memory, front-panel operation and feedback, and intelligent RS-
232 control. Designed for global applications, the 232-STSi is CE listed and receives PAL B/G/ H, D/K, and I standards, 
as well as SECAM B/G, D/K, and L. 
 
The 232-STSi features a new, versatile solution for auto-tuning broadcasts that allows the user to mix and match 
different TV standards. For example, a viewer in Germany (PAL B/G, A2 audio) can also save presets for Belgian 
broadcasts (PAL B/G, NICAM audio). Channel preset search, TV standard, add, and delete can be controlled from 
optional iC-RC remote or control system programming. 
 
An onboard character generator displays on-screen text for closed captioning, channel names, interactive menus, and 
system feedback. Switchable inputs for composite video and stereo audio are included for display of PC graphics, VCR, 
camera or other A/V sources. AV from inputs and off-air broadcast are output as composite video, S-Video and Stereo, 
Mono, or Dual audio.
