NLC 4x2.0: Four Stereo Pairs of Loudness Control

Neural Loudness Control 4 x Stereo gives you the ability to independently process four stereo channels of audio simultaneously while only occupying one rack unit of space. NLC 4x2.0 is often used in large facilities were space, power and heating constraints require a higher-density solution.

Neural Loudness Control: Control the loudness, don't squash it.

Neural Loudness Control (NLC) is an advanced loudness leveling technology that accurately measures and regulates the perceived loudness differences in audio. Annoying side-effects of traditional audio processing are eliminated and loudness is controlled without squashing the quality of the audio. The result is audio with a natural, open quality and a consistent audio experience for all viewers.

NLC actually mimics human perception of audio and provides tight control of loudness. Neural's Loudness Measurement detects spectral and density differences, inter-channel relationships and temporal overlaps within the audio signal. After detection, NLC applies the appropriate gain or attenuation to the audio to achieve a user-defined loudness level.

If NLC is used ahead of an AC3 (Dolby Digital) transmission, the target loudness level will also match the DialNorm metadata information, thus providing viewers with a consistent audio experience.

Key Benefits of Neural Loudness Control

• Guarantees a consistent viewer experience despite variations in consumers' equipment
• Adheres to the ITU BS.1770 loudness recommendation, and--more importantly--agrees with your viewer's perception of loudness
• Uses the same loudness control for stereo and 5.1 surround content
• Manages loudness without a "squashed" or compressed sound
• Corrects loudness while preserving the original equal loudness curve
• Using look-ahead technology, makes large gain corrections imperceptible
