7.13. 7814 AUDIO ARCHITECTURE

All 7814 series modules incorporate a similar audio architecture. Figure 7-22 depicts this architecture.
Internally, 16 channels of audio are processed within the module. Once input audio channels are selected,
auto-sensing audio sample rate conversion and adjustable audio delay is applied. All advanced audio
processing steps, such as audio up-mixing, down-mixing and adjacent channel mono mixing, have
simultaneous access to all 16 channels of input audio.
Finally, sixteen independent Output Channel Mixers generate sixteen channels of output audio. These
Output Channel Mixers perform any required audio inversions, audio gain adjustments and audio channel
swapping. Using the X and Y inputs of each Output Channel Mixer an additional level of mono mixing is
also available for each channel of output audio. AES audio outputs and embedded audio outputs can
carry different audio.
