Itel D-PRO 6
D-PRO 6 digital audio processor is a multi-band audio processor for sound processing, optimized for use in the D-TV environment.
The processing chain includes a two-band AGC that feeds the six-band limiter.
The final clipper-limiter operates at 96KHz and has been optimized to contain the distortion caused by this, allowing to obtain a clear sound and free of artifacts common to digital clipping.
The audio processing is realized through DSP, allowing to have a stable operation over time and the possibility of implementing new functions through software updates.
The loudness control, compliant with ITU-R BS.1770, allows to maintain a constant perceived volume level even with different types of audio input, such as movies, talk shows or music videos.
The version for D-TV use is supplied with SDI interface.
The same device can then process the audio already present in a SDI signal (SD - HD - 3G), or act as an audio embedder, inserting the audio from the analog or AES/EBU input in the SDI signal.
There is also an audio delay line to allow synchronization with the video signal.
In case of malfunction the device will automatically exclude itself, connecting all the outputs to the respective inputs.
