Audio In
The new CS48DV2B supports a host of signal processing
applications concurrently, including the mass production-ready
Dolby Volume solution. See Section 3. for details about
firmware concurrency on the CS48DV2B. The target
applications for the CS48DV2B DSP are:
—
Digital Televisions
—
Soundbars / DTVs with Integrated Soundbars
—PMD/iPod Docking Stations
—
Automotive Head Units
—
Automotive Outboard Amplifiers
—
Blu-ray Disc & DVD Receivers / HTiBs
—
PC Speakers
All of these applications and many more that use volume
control and are subject to playback from sources that do not
have consistent volume levels will benefit from the CS48DV2B
Dolby Volume solution.
