4 The DEE28 Card
Introduction
The DEE28 is a next generation Dolby multi format decoder and Dolby
E encoder with quad speed ADD-ON audio bus. It replaces the popular
DBD08 and DBE08 on a single card. Based on the Dolby’s Cat. No.
1100 sub module it is capable of
decoding Dolby E, Dolby Digital and
Dolby Digital Plus and encoding to Dolby E . The enhanced feature set
includes the capability of decoding 7.1-channel Dolby Digital Plus or
5.1-ch Dolby Digital 5.1 with audio description, carried in a single
bitstream (Single PID), or as two bitstreams (Dual PID).
In addition to the extensive Dolby Decoding capabilities this card can
add a voice activated (or triggered by GPI) Voice Over signal to any of
the decoded streams or plain PCM streams that could enter the unit.
Individual delay and gain controls are available for all decoded or plain
PCM streams that entered the card. A dual mode I/O configuration is
possible with physical 2x AES/EBU in and 6x AES/EBU out or 4x
AES/EBU in and 4x AES/EBU out.

internal streams

GPI trigger of VO is included

GPI can be used as ‘cough button’ to mute unwanted voice
activated mixing

Physical metadata output



Individual gain control per channel (except bitstream input)



Full audio channel shuffling

Loudness measurement according to ITU BS.1770-1 and ITU
BS.1770-3 (CALM and R128)

A tone generator is included that can be controlled by the
loudness measurement.

It will generate a -20dBFS sinewave when the loudness
measurement reads and measures -20LUFS so a normal
peak/VU/dBFS meter can be used to read loudness
