232-STSi
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, H, D, K, and L formats.
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. Up to nine tuners can be integrated from one RS-232 control port.
VTunes PAL CATV and off-air frequencies, storing up to 125 Channel Presets in memory
VFeatures intelligent auto-tuning of TV frequencies, with the ability to save channel presets that include the
frequency and TV Standard
VDelivers balanced A2/NICAM Stereo audio with programmable volume levels, as well as Mono and Dual A/B audio
VOutputs S-Video signal for improved image quality for monitors, large-screen displays and video projectors,
employing adaptive comb and anti-aliasing filtering, as well as cross-color and cross-luminance reduction
VSwitches between tuner and composite AV inputs, outputs simultaneous composite and S-Video
VOperates using one of several control pathways:
- Full bi-directional RS-232 control and status feedback, AMX and Crestron modules available
- PC control using free Tuner Helper software (great for saving tuner channels and setup information)
- Front-panel programming options for tuning, RS-232 and operation setup
- Optional IC-RC IR wireless remote, discrete IR and wired IR codes, as well as contact closure channel up/down
VProvides front-panel control for A/V Mute, mode select, and channel up/down
VDisplays closed-captioning (LIne 22) and on-screen text channel names, interactive menus, and system feedback
VInserts blue screen video image when unit senses loss of video level
VUpdates firmware with easy-to-use S12 Flash software, available from CR website
VMounts in 19" rack with optional RK1 or RK2 kit for dual side-by-side installation
