6.36. DOLBY E ENCODER MIXER TAB
The 7812 series module can encode Dolby E with the Dolby E options installed. There can be more than
one Dolby E module installed. The controls for each Dolby E encoder are identical. Since each Dolby E
Encoder Control tab is identical, only Dolby Encoder A will be described.
As shown in Figure 6-41, there are eight individual Dolby Encoder Channel Mixers in 7812 series
modules. These Channel mixers perform audio inversion, audio gain adjustment and audio channel
swapping for each of the 8 Dolby audio channels. Using the X and Y inputs of each Output Channel Mixer
an additional level of mono-mixing is also available for each channel of audio.
