NAB 2011: Wohler Technologies Products Preview

2011 NAB Show Preview

Booth N2524

Wohler Technologies will demonstrate its range of signal management solutions.

MADI-8 Audio Monitor (New)—Making its international debut, the new MADI-8 audio monitor lets broadcasters implement the Multiple Audio Digital Interface (MADI or AES10) in their production workflows. MADI is an industry-standard electronic communications protocol for an interface that carries multiple channels of digital audio. MADI is extremely desirable for outside broadcasters since it greatly reduces the amount of cable and weight associated with traditional analog- or AES-based audio distribution. Similar in appearance and operation to Wohler’s VMDA-SUM8 eight-channel analog/digital continuity monitor, the MADI-8 can be connected in series within a 64-channel MADI stream to audibly monitor up to eight channels. The 1RU monitor features a 16-character by two-line LCD display as well as both coax and optical MADI inputs and outputs, mixed two-channel or mono analog outputs, channel presence indicators, and eight user-nameable presets.

AMP2-16V Series Modular Audio/Video Processing Monitor—Wohler will present major functional enhancements to its flagship AMP2-16V audio/video processing monitor. Highlights include support for SMPTE 2020 metadata monitoring, a menu lockout function that prevents unauthorized changes to the unit’s configuration, the ability to cycle through solo monitoring of defined clusters of audio channels at the press of a button, an optical SPDIF input option for monitoring the consumer’s set-top box (STB) experience, and improved display of metadata and stream status information. To facilitate the additional information that can be displayed, the system gives operators free rein in using both screens as they wish, including the possibility of putting metering on one screen and status/metadata on the other. These new updates are available as a simple upgrade to all current AMP2-16V owners and come standard on all new AMP2-16V units.

Pandora Loudness Analyzer—Pandora is a compact desktop or optional rack-mountable loudness monitor with logging that can be employed at any point in the broadcast chain. In helping broadcasters to address the demands of global loudness standards, the Pandora monitor provides a clear, accurate reading of loudness measurements for any SDI video signal with audio. Accepting and analyzing embedded audio in either SDI or AES streams, Pandora gives the user an accurate reading of loudness measurements (LKFS/LUFS) over a user-defined period of time, ranging from 400 milliseconds to 60 minutes. Logs for each session are stored for review at any time.

Presto Multiview Source Selector (New)—This new multiview source selector makes 16 3G/HD/SD-SDI video channels readily available for monitoring and straightforward switching via integrated OLED pushbuttons. Following on the success of Wohler’s Touch-It digital multichannel video monitor and controller, Presto is a compact 1RU solution with 16 OLED screens, each of which serves as a switching button that displays the video stream from any source.

HDCC-200A Captioning Cards—These captioning cards allow users to handle encoding, decoding and monitoring of CEA608, CEA708, WST and OP47 captions, as well as encoding and decoding of multiple GPI triggers. Based on Wohler’s award-winning flexible HDCC-200A card design, broadcasters may choose the functionality their application requires.
