3 9901-UDX Function Submenu List and Descriptions

3-48 9901-UDX PRODUCT MANUAL 9901-UDX-OM (V1.15)

Provides upmixing of any normal PCM stereo pair into

5.1 surround sound audio which in turn can be applied

to six user-selectable channels. (Option +UM)

Upmixing

Note: • For any six channels selected for this function, the Left and Right channel selections always serve as the stereo input pair.

• Upmixing induces a 6 msec delay into the audio. This delay can be removed by setting either the bulk or channel Audio/

Video Delay controls to introduce a -6 msec advance. See Audio Bus Input Routing/Controls (p. 3-33).

• 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 three of the selected channels

designated as Center, Left Surround, and Right Surround are

below the level threshold set using the 5.1 Detection Threshold

control (described below), upmixer produces new 5.1 content

generated by the upmixer.

• If detected signal level on any of the three of the selected channels

designated as Center, Left Surround, and Right Surround is

above the level threshold set using the 5.1 Detection Threshold

control, upmixing is bypassed and the channels fed to the upmixer

pass unaffected to the upmixer outputs.

• 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

input audio channels pass unaffected to the upmixer output.

• Upmixer Input Channel Selection Separate drop-down lists for Left, Right, Center, LFE, Left Surround,

and Right Surround allow a stereo pair to be upmixed to 5.1-channel.

The example here shows selection of bus channels 1 and 2 as the

received stereo source (Bus Ch1 and Ch 2 for Left and Right drop-down

list selections in the Upmixer Selection tool).

Using the setup shown in the example, when upmix is active (either forced

upmix or auto-enabled) the Upmix L thru Upmix Rs channels comprise a

5.1-channel upmix of the input stereo pair. If any content is present on the

monitored C, LFE, Ls, or Rs input channels whose is above a

user-defined level threshold (Bus Ch 3 thru Ch 6 in this example), all six

inputs channels pass through the upmixer, with upmixing bypassed.

Upmixer output channels Upmix L thru Upmix Rs are available as

sources for the card audio output routing.
