(V4.0)
Controls the AES Audio Input features for the eight AES
pairs, and displays signal status for the AES pairs and
the 16 embedded audio channels. Also provides global
unity routing/parameter control resets.
Note: Also refer to AES Audio Input Advanced Features (p.
1-18) in Chapter 1 ,― Introduction‖ for detailed
information regarding these functions.
• AES SRC
•
•
Individual SRC Disable control for each AES pair (1 thru 8) disables or
enables Sample Rate Conversion (SRC) bypass as follows:
• Disabled: In this mode, AES SRC for the corresponding AES pair is
bypassed. SRC is set to Disabled by default. This mode is
preferred where the AES rate matches the input video rate. This
mode is necessary when embedding non-PCM AES audio such a
Note: In this mode AES rate must match the input video rate or
Note: AES audio must be nominally 48 kHz.
• Enabled: In this mode, AES SRC for the corresponding AES input
pair is enabled. SRC enabled allows the UPC-166 to interface
with asynchronous AES sources (sources in which the AES timing
does not match the video reference timing). SRC can be used to
the input video stream.
• AES Passthrough
•
•
•
Individual AES Passthrough On/Off control for each AES pair (1 thru 8)
disables or enables Passthrough as follows:
• Off: Disables AES passthrough for the selected AES input pair.
Passthrough is set to Off by default.
• On: Passthrough is turned on, with the corresponding AES output
pair to act as a bit-for-bit copy with zero delay of the corresponding
AES input pair.
Note: AES Passthrough set to On overrides normal audio routing.
