D-PRO 6 is a digital multiband audio processor optimized for television broadcasting.
The audio processing chain comprises a two bands AGC which feeds the six bands limiter-compressor, followed by a final clipper-limiter operating at 96KHz, optimized for distortion masking, thus obtaining a cleaner and clipping artifacts free sound.
The audio processing are realized through DSPs, allowing a stable operation over time and the possibility to implement new functions through software updates.
The loudness limiter can equalize the perceived loudness among different audio program sources such as live shows, commercials, films, music videos.
It operates according to the ITU-R BS.1770 standard.
The D-TV version is equipped with SDI audio embedder-deembedder with automatic bypass in case of failure.
This version can process the audio stream already embedded into the SDI (SD - HD - 3G) signal, or can be used as an audio embedder to insert the audio coming from an external source into the SDI signal.
An adjustable delay line will help in lip-syncing the embedded audio to the incoming video.
All outputs will be bypassed to their respective inputs in case of malfunction.
