Note: • 2.0-to-5.1 upmixer function is an optional licensable feature. This function and its controls appear only when a license
key is entered and activated. Refer to Licensable Features function description on page 3-19 for more information.
• Channel sources used by the upmixer are post-processed signals received from the Audio Routing/Gain Control
function. When active, the channel selections made using this function are directly routed to the AES discrete pairs.
Refer to 2.0-to-5.1 Upmix Function (p. 1-9) in Chapter 1, “Introduction” for detailed functional description and signal flow.
• For any six channels selected for this function, the Left and Right channel selections always serve as the stereo input
pair.
• 2.0-to-5.1 Up Mixer Selection Separate drop-down lists for Left, Right, Center, LFE, Left Surround,
and Right Surround allow AES audio source selection, and channel
assignments for the six generated 5.1 channels.
The example below shows selection of AES channels 1 and 2 as the
received stereo source (AES Ch1 and Ch 2 for Left and Right drop-down
list selections in the Up Mixer Selection tool).
Using the setup shown in the example, when upmix is active the AES
channel 1/2 stereo pair is overwritten with the new stereo pair L/R on
channels 1/2. As selected in the example, the additional 5.1 channels C,
LFE, Left Surround (Ls), and Right Surround (Rs) overwrite AES Ch 3 –
Ch 6, respectively.
• Up Mixer Mode Control Enables or bypasses upmixer as follows:
• Auto: Automatic enable/bypass of 5.1 upmix function as follows:
• If detected signal level on all four of the selected channels
designated as Center, LFE, Left Surround, and Right Surround
are below the level threshold set using the 5.1 Detection Threshold
control, upmixer overwrites all six selected channels with the new 5.1
content generated by the upmixer.
• If detected signal level on any of the four of the selected channels
designated as Center, LFE, Left Surround, and Right Surround is
above the level threshold set using the 5.1 Detection Threshold
control, upmixer is bypassed and the original channels pass
unaffected.
• Always Upmix: Manual enable turns on upmixer and overwrites content
on all six selected channels with new 5.1 content generated by the
upmixer regardless of original signal level or content.
• Bypass: Manual disable bypasses the upmixer. When bypassed, the six
selected audio channels pass unaffected.
