Request more information or contact us now for purchasing information.


C2-2100A Down Converter is based on TV One's exclusive CORIO®2 technology and provides high quality conversion from DVI and analog PC or HD sources to standard video formats. The input can be any analog computer resolution up to 2048x2048 and 1080p or any DVI resolution up to 1920x1200 and 1080p. A wide variety of computer signal formats are available to support PC, Mac and Workstation formats. Our exclusive AutoSet feature takes the hassle out of setup by automatically sizing and positioning the computer image to fit exactly on the video screen. An analog computer input signal bypass (loop-thru) is also provided. The output is simultaneously available in Composite, S-Video (YC), YUV and YPbPr. NTSC, PAL, PAL-M, PAL-N, SECAM output standards are supported. The C2-2105A provides an SD/HD-SDI output as well as all the other features of the C2-2100A.

All settings are stored in non-volatile memory and are retained even when power is switched off. Ten user defined presets are also available to customize settings for various applications. All the functions can be controlled via the front panel Push Buttons, Infrared, RS-232 or IP. A Windows Control Panel is provided and most third party control systems interface directly with the entire C2 range of products. A front panel LCD makes setup easy. The unit is housed in a desktop case and an optional rackmount kit is available that holds one or two units.

Variable Zoom to 10X enlarges any part of the computer screen to fill the entire video screen and position controls allow movement to any area desired. Variable Shrink to as little as 10% allows fitting the image onto most displays. The advanced Digital Flicker Elimination circuitry and high sampling rate insures crisp, clear images, while full bandwidth chroma sampling insures faithfully reproduced, high resolution colors. Temporal interpolation greatly improves frame rate conversion by analyzing and merging successive frames. Pixel Level Motion Adaptive Diagonal Interpolation insures high quality de-interlacing of PAL and NTSC signals. The Composite Video Genlock feature insures precise synchronization of the incoming signals by providing a wide Subcarrier lock range with SC phase adjustment.

C2-2150A Advanced Features - In addition to all standard C2-2100A features. The Key Mode allows computer graphics to be keyed over an external Composite or YC signal. The keyed image may be faded in and out. Due to the 4:4:4 sampling format, precise keying at the pixel level can be achieved. The Mix Mode permits Seamless Cut, Fade or Wipe transitions between input sources. The PIP Mode allows either of the computer inputs to be inset in a window over either of the video inputs or vice versa. The PIP window may be placed anywhere on the screen. The C2-2155A provides an SD/HD-SDI Output as well as all the other features of the C2-2150A.

Input Expansion is possible by using the optional S2 Series Input Expansion Switchers for DVI or RGB/YPbPr. These units link to C2 unit via an OPTIONS Interconnect Cable and become an integral part of the main unit from a control and operational standpoint. The routing of these additional inputs is controlled directly from the control system of the C2 unit and multiple different S2 models may be simultaneously connected.

Advanced Stereo Audio processing and switching is available via the optional S2-106AD Input Expansion Switcher, providing six differential audio inputs, which can be used for low impedance balanced or high impedance unbalanced sources. The user controls audio level, audio sampling frequencies and up to 999ms of adjustable audio delay independently for each input. The unit has numerous choices for audio I/O connectors, including a terminal block. The S2-106AD connects to the C2 unit via the OPTIONS interconnect cable and is then fully integrated into the control system of the host unit.
