Video Products and Solutions:

Touch-it™ Series Touch Screen Video Switchers

Wohler's award-winning Touch-it™ series of 3RU touch screen video switchers includes the Touch-it 12-channel CVBS (composite) analog video monitor, Touch-it Digital eight-channel (or 16-channel with optional inputs) HD/SDI image viewer and switcher, and the Touch-it Plus CVBS/analog 12-channel video/audio confidence monitor and switcher. Each system combines a variety of features in a compact package that provides flexible confidence monitoring in space-critical environments. In addition to providing versatility in viewing and routing video signals, these multi-image viewers are configurable to display four, eight, 12, or 16 live images — all for a list price far below the per-channel rate of many other multi-view models.

Each Touch-it multi-image viewer features a high-resolution 7-inch widescreen LCD touch screen on one side and a full-size target screen on the other. Sources (NTSC or PAL autosensing) are displayed as thumbnails on the touch screen display, with the selected signal displayed on the target screen and simultaneously transmitted to a multi-rate BNC connector output. The front panel incorporates a headphone jack, internal speakers, and internal/external audio monitoring switches, allowing operators to route audio to the line out, internal speakers, or both.

HDMon Family of High Definition Monitors

Wohler's family of high definition color video monitor displays, the HDMon series, enables high-quality monitoring of digital HD-SDI, SD-SDI, or DVI signals; analog composite, component, and RGBHV video; and CGI images up to WUXGA resolution. HDMon systems on display will include the 19-inch HDMon 190, the 9-inch widescreen HDMon-90WS, and the dual 9-inch widescreen HDMon-92WS.

Though the HDMon series is designed primarily for 1080-line HD applications, each monitor provides exceptional noise reduction, motion interpolation, and motion-adaptive processing to ensure crisp, clear display of images, regardless of their native resolution. Operating either as a desktop monitor or installed in a 19-inch-wide rack, these LCD displays offer HD resolution, a choice of 4:3 or 16:9 aspect ratios, user-adjustable scaling, and up to 170 degrees of perfect off-axis viewing without the image and color distortions normally associated with LCD displays. A sleek, lightweight design allows HDMon displays to convert from portable to tabletop solutions without the need for additional hardware. Built-in 100Base T Ethernet and RS232 connections allow the monitors to be configured and controlled remotely via a Windows®-based GUI or by third-party control systems.

The MON4-2W/HR and MON2-3W/HR high-resolution display monitors feature four 4.3-inch and two 7-inch wide-format LCD panels respectively, each of which features dedicated recessed controls for contrast and brightness, native 16:9 aspect ratio, and selection between 16:9 and 4:3 aspect ratios for SD-SDI signals, as well as tally indicators and independent power and input termination switches. Both models automatically detect and accommodate NTSC and PAL video formats. Each LCD is mounted in a cylinder and thus may be rotated approximately ±30 degrees in the vertical plane for optimum operator viewing angles. The monitors' rear panel features four SDI inputs and four SDI outputs (buffered and equalized) on BNC connectors and a green LED indicating the lock status of the attached HD/SD-SDI source signal. A DB-25 connector on the rear panel can be interfaced to most tally systems.
