below. See Chapter 5: Specifications for specific pinouts.
• Main Audio Input: Connect the PCM signal which will be upmixed to create a 5.1 chan-
nel signals to this input.
• Mix Inputs: PCM signals connected to these inputs can be selectively mixed with the
output of the upmixing algorithm. These are useful for adding announcer via the C (cen-
ter) input, or stereo "natural," "crowd," or "ambience" audio via the Ls/Rs (Left sur-
round/Right surround) inputs. Lf/Rf (Left front/Right front) inputs are useful for
placing audio in the left and right main outputs with no additional processing.
• Main Audio Outputs: Main processed digital audio outputs with the SMPTE 320M
standard channel configuration: Left/Right, Center/LFE, Left Surround/Right Sur-
round. An Lt/Rt compatible downmix of the 5.1 channel output is always available on
the Lt/Rt output connector and is useful for monitoring or feeding systems such as
NTSC which support only two audio channels.
NOTE: The main audio inputs are hard-bypassed to the Main Audio Outputs during
boot and bypass (power off) conditions to support mission-critical applica-
tions. Under these circumstances, each input connector bypasses to the
output connector directly below it, passively maintaining audio continuity.
