Encoding Dolby E, Dolby D/AC-3 (7630, 7635 Software Key Option Required)
If you have purchased the 7630 Dolby E Encoder sub module and software key option, or the 7635
Dolby D/AC-3 Encoder sub module and software key option, you can encode up to four pairs, or one
stream. Select which mixer channels you want to send to the encoder by using the Encoder menu.
Signals going out of the encoder are compressed.
Specifying the Mixer Channels to be Encoded
To specify the mixer channels to be encoded, make a selection from one or more of the Encoder In
Sel drop-down controls on the Encoder menu. From each control, you can choose from the following
pairs of mixer channels:
Mixer 1/2, Mixer 3/4, Mixer 5/6, Mixer 7/8, Mixer 9/10, Mixer 11/12, Mixer 13/14, Mixer 15/16
When encoding a Dolby D/AC-3 stream, a maximum of 6 channels are encoded. When encoding a
Dolby E stream, a maximum of 8 channels are encoded.
The Encoder Type field reports which type of encoder is installed.
Meta Data Src: Use this control to select Serial 1, Serial 2, Serial 3, Serial 4 or Decoder as the source
of the Dolby metadata going into the signal being encoded. The serial ports go through the 15-pin
D connector. Note that you must first configure the jumper connectors to work with data before you
can use the serial ports in this manner. See Configuring the Analog Audio and Balanced Digital Data
Jumper Connectors on page 10 for details. The encoder will always have access to the decoder as
the source of metadata even when the decoder is configured to send metadata out through one of
the serial ports.
