1 9061 Functional Description
1-16 9061 PRODUCT MANUAL 9061-OM (V4.9)
The examples in Figure 1-7 show the automatic enable/disable up-mixing
function applied to example selected channels
Emb Ch 1 thru Emb Ch 6. As
shown and described, the processing is contingent upon the signal levels of
the channels selected to carry the new 5.1 upmix relative to the selected
threshold (in this example, -60 dBFS). Note also that this function is applied
after the Audio Routing/Gain Control function. Because all audio inputs pass
through the Audio Routing/Gain Control function before the up mixer, the up
mixer can use embedded, AES discrete, and/or analog audio sources.

With all detected signal levels on
EmbCh3– Ch 6 below
threshold, upmixer is active and
overwrites with new 5.1.

5.1 Up Mix
Because the selected channels are
already carrying viable content,
upmixing is bypassed, allowing the
six original Emb Ch 1 – Ch 6 to pass
unaffected.
With any detected signal levels
on Emb Ch 3 – Ch 6 above
threshold, upmixer is bypassed.

Note: In either case shown here, the unselected
channels (in this example, Emb Ch 7 thru Ch
16) are not involved in this process and always
pass unaffected.
