Dolby DP571 E Encoder

This Dolbly DP571 is used but is in good condition, it features some cosmetic marks on the bottom and top of the unit from previously racked but the front panel is in near mint condition. The Dolby DP571 is an encoder that Encodes up to eight channels of digital audio and metadata for use in DTV program production and broadcast distribution. The Dolby E multichannel distribution system is the first technology that can transport multichannel audio within the digital broadcast industry’s current two-channel infrastructure. A single Dolby E bitstream can carry up to eight discrete audio channels, each with its associated Dolby Digital metadata, in a 16- or 20-bit, 48 kHz AES pair.

The DP571 encoder and DP572 decoder employ an almost identical front-panel user interface. The devices are also similar to some of the Dolby Digital series of encoders and decoders, which may be familiar to broadcast engineers.

Since Dolby E’s audio and video frame rates are identical, many common editing and switching practices can be performed on the encoded bitstream without causing mutes or other disturbances in the decoded PCM audio. For editing tasks that require decoding, Dolby E’s sophisticated audio coding algorithm allows ten or more encode/decode cycles without audible degradation; this exceeds the requirements of even the most elaborate program contribution, distribution, and emission paths.
