HD World 2010: 22-foot Wohler Mobile Trailer Features Spatial Solutions

At HD World 2010, Wohler (booth 1301) will showcase it’s a wide variety of products, including a Wohler Mobile, a 22-foot-long trailer packed with the company’s audio, video, and data monitoring solutions. The unit presents highlights how easily the solutions fit into space-constrained production applications.

Wohler Mobile will highlight the AMP2-16V, the latest in Wohler’s line of 16-channel modular monitoring systems which combines video monitoring with comprehensive audio management capabilities including loudness control. Also featured will be Wohler’s new Pandora system for clear, configurable loudness monitoring at any point in the broadcast chain.

Wohler’s AMP2-16V Series 16-channel audio/video processing monitor is a new dual 4.3-inch OLED version of the company’s AMP2-16 Series modular audio monitor. The monitor features dedicated video monitoring, loudness metering and control, audio mixing and routing, SDI audio embedding, and instantaneous Dolby bit stream analysis, called Dolby Zoom.

Dolby Zoom, applied to all installed digital modules with a Dolby upgrade, dynamically switches between the standard overview of monitored channels and monitoring of the decoded channels and metadata of an available Dolby bit stream with a single button press. The full trim, pan, and routing controls of the mix mode feature reduce dependence on mixing consoles, and can be adjusted from the main metering screen, which features simultaneous color- and scale-adjustable metering of up to 16 channels of audio from a choice of input and output modules including 3G/HD/SD-SDI, AES, and analog.

Also on display is variable-timescale loudness metering and selected metadata. In addition to the same user interface and help system as before, front-panel hotkeys can now be assigned not only to solo or mute groups of channels and recall system-wide presets, but also to activate Dolby Zoom on a target source or adjust the audio level of individual output channels.

The Pandora Loudenss Meter is a compact and easy-to-read desktop or rack-mountable loudness monitor that can be employed at any point in the broadcast chain to provide simple, accurate loudness monitoring. In helping broadcasters to address the demands of the CALM (Commercial Advertisement Loudness Mitigation) Act and other standards, the Pandora monitor provides a clear, accurate reading of loudness measurements for any SDI video signal with audio.

Accepting and analyzing SDI, AES, stereo, or multichannel audio, Pandora gives the user an accurate reading of loudness measurements (LKFS) over a user-defined period of time, ranging from five seconds to 60 minutes. A large numerical display shows LKFS readings, and a warning light indicates when this value exceeds acceptable thresholds. The unit’s graphic display shows changes in loudness over time and real-time loudness (LU) levels at a glance. Additionally, Pandora allows users to set a range of loudness parameters, including reference level, gating, and integration time; configure the system for 2-, 4-, 6-, or 8-channel (AES or SDI) operation; or use a contribution matrix for multichannel mode.
