LDP-8242 Multi-Definition Loudness Processor

The LDP-8242 is ideal for correcting irritating loudness differences between programs and commercials. Featuring 24-bit audio processing that supports 16 channels of embedded audio from an HD / SD SDI signal.

With Linear Acoustic AEROMAX™ technology, the card applies loudness control on up to 6 channels of audio from any of the 16 channels of embedded audio. Linear Acoustic AEROMAX™ algorithms use a sophisticated multiband approach to loudness processing. These algorithms can apply multifacted loudness correction specifically targeted to various frequency ranges and other characteristics within the program material, resulting in audio free from abrupt loudness or image shifts while preserving more of the original content than previously possible.

An optional discrete AES option provides 16 channels of discrete audio support, with 8 AES pair BNCs, which can be configured as inputs or outputs. The AES-8242 option provides discrete audio loudness processing as well as 16 channel embedding / de-embedding.

Optional Linear Acoustic UPMAXTM upmixing technology allows legacy stereo program audio to be converted to 5.1 channel audio, with the UMA-8242 option.
