Audio Meters for Teranex AV only
The Teranex AV allows you to select which pair of input or output audio channels willbe
displayed on the front panel LCD. The channel numbers are displayed below themeters
forconfirmation.
When a Dolby Digital or Dolby E encoder is installed in the Teranex 3D, two additional
selections will appear in the Audio Menu:
Dolby Encode Menu
The ‘dolby encode’ menu will allow you to select your source for each channel to be encoded.
For Dolby Digital encoding, you may select up to 6 channels to be encoded. For Dolby E, you
may select up to 8 channels.
You may select from discrete audio channels, Dolby decoded channels if a Dolby decoder is
installed, test tones or mute. This menu is similar to the ‘output mapping’ menu, but you should
understand that the sources selected in the ‘dolby encode’ menu will be mapped to two Dolby
encoded channels, which may later be mapped to your output.
As an example, let’s say that you need to encode input channels 3 through 10 to Dolby E and
you want your Teranex to provide Dolby E encoded audio outputs on SDI channels 9 and 10.
 First, you would use the ‘dolby encode menu to route ‘input 3’ as the source for Dolby
Encode channel 1.
 Press the ‘next’ button on the menu to move to Dolby Encode channel 2 and route
‘input 4’ to it. Continue this process until you have routed the remaining input channels
5-10 to Encoder channels 3-8.
 The 8 input sources routed to the Dolby E encoder module will result in two encoded
output channels. Using the ‘output mapping’ menu in the ‘audio menu settings’ section
of this manual, you would map the two Dolby E encoded channels, which we call
‘encode 1’ and ‘encode 2’, to your SDI output channels 9 and 10.
Dolby Metadata Menu
‘Dolby metadata’ describes the encoded audio and conveys information to control downstream
equipment. Metadata is usually carried in the Dolby Digital or Dolby E bitstream, but can also be
carried as a serial data stream between Dolby E and/or Dolby digital equipment.
