Professional Digital Audio and Metadata Monitor™, a complete package for highly accurate digital audio and metadata monitoring throughout the entire broadcast chain at this year’s IBC (Stand 8.D29).

“The LAMBDA is the first audio monitor that can decode Dolby Digital (AC-3) directly from an applied DVB-ASI transport stream, analyse the results via ITU-R BS.1770 loudness measurement, and display critical metadata information helping broadcasters ensure an optimal audio experience for viewers as well as compliance with standards and regulations,” says Tim Carroll, founder and president of Linear Acoustic.

The LAMBDA displays both audio and metadata, and allows simulation of metadata effects to provide accurate monitoring. The base model includes standard features like AES and HD/SD-SDI inputs, ITU-R BS.1770 loudness measurement, and a premium acoustically tuned speaker system with digital crossovers and bi-amplification, full-time 2-channel LtRt or LoRo downmix via AES and balanced analog outputs, AES outputs of decoded and/or de-embedded audio channels, and a powerful front panel headphone output. Options include Dolby Digital (AC-3)/Dolby E decoding, DVB-ASI input, and dual power supplies.

Unique front-panel controls allow quick stepping through any channel, channel pair, or downmix. Numerous presets can be created, saved and quickly recalled for different monitoring tasks. The display features metering of eight audio channels plus numeric loudness and metadata indication.

LAMBDA is part of a wider Linear Acoustic initiative to provide a comprehensive range of solutions that allow broadcasters to ensure content conforms to on-air standards while preserving the original quality.
