Video Products and Solutions

RM LCD Video Monitoring Series

Packed with functionality but priced affordably, Wohler's new RM series of high-definition (HD) monitor packs are ideal for video and audio confidence monitoring in mobile trucks, news and transmission control rooms, and duplication and post-production facilities. Each screen can display eight channels of VU over PPM audio level meters, UMD, safe areas, frame marks, cropping, switchable aspect ratios, and built-in color bars. The RM HD units also provide an active loop-through output for each SDI input. All settings are accessible from front-panel controls and the RM's intuitive on-screen menu. As a fully inclusive solution designed for high-resolution HD imaging, each unit features built-in NTSC and PAL autosensing and accepts two composite video inputs per screen on the same BNC used for HD/SD-SDI.

Additional features include a versatile chassis in which the LCDs may be rotated ±55° in the vertical plane to provide optimum viewing angles. Red/green/yellow tally, as well as the in-screen UMD, can be interfaced to most tally systems.

HDMon Family of High Definition Monitors

Wohler's family of high-definition (HD) 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. 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.

Current HDMon models include the HDMon-90, HDMon-90WS, HDMon-170, HDMon-92WS, HDMon-190, and HDMon-260. Whether operating 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 requiring 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.

MON Family of High-Resolution Display Monitors

The compact yet flexible design of Wohler's MON high-resolution display monitors is ideal for confidence monitoring of multiple video feeds for mobile trucks, news and transmission control rooms, duplication facilities, and post-production applications. Monitors in the MON family feature from two to eight wide-format LCD panels, situated side by side, each with dedicated recessed controls for contrast and brightness, a 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.

All 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 SDI inputs and SDI outputs (buffered and equalized) on BNC connectors, with a green LED indicating the lock status of the attached HD/SD-SDI source signal.

Touch-it™ Digital Multichannel Video Monitor

Wohler's Touch-it™ Digital offers unique multichannel video monitoring functionality in a smart, affordable design. The 3RU system features dual seven-inch high-resolution color LCD displays. The left monitor is a touch screen that displays from four to 16 thumbnail images. When one of these images is touched, that video source appears on the right monitor at full size. The video source's HD/SD-SDI source signal is then sent to an unbalanced output and to a VGA output for monitoring on an external display. Touch-it Digital accepts and switches up to 16 HD/SD-SDI video inputs, passing along any embedded audio. When combined with a Wohler openGear™ frame with closed captioning and logo keyer cards, the Touch-it Digital serves as an elegant and cost-effective master control system.

Digital AMP Series Monitoring Systems

Wohler's digital AMP monitoring systems offer premium-quality sound and professional level metering in a compact package. Wohler's HD World 2008 booth will showcase the AMP2-S8MDA audio monitoring system, which provides eight-channel analog, AES/EBU, HD-SDI, and SD-SDI digital multichannel audio monitoring and conversion, as well as professional level metering in a compact 2RU cabinet.

Wohler also will feature the AMP2-E8MDA multi-format audio monitor, which processes and monitors up to eight channels from a Dolby® E or AC-3 (Dolby Digital) bit stream, an HD-SDI or SD-SDI bit stream, two sets of four AES/EBU signal pairs (balanced and unbalanced), or eight balanced analog channels. Close cooperation with Dolby® Laboratories ensures that these products meet high standards for the monitoring of both Dolby E distribution and Dolby Digital emission coding systems. Users of these AMP systems can switch seamlessly between encoded or discretely embedded sources, in addition to providing a simultaneous demuxed output of the multichannel source.

Both systems feature eight high-resolution, 53-segment tricolor LED bar graph audio-level meters to enable instant and accurate level monitoring at a glance. The unique acoustic design of these AMP2 units provides optimally focused sound in an ultra-near-field environment, which gives the operator a higher sound pressure level while reducing overall ambient sound and adjacent bay crosstalk.
