Mentor CX
AES/DARS (unbalanced via BNC)
AES signals from the Mentor RG can be transmitted as
unbalanced via a 75Ω BNC output, or
balanced via a D-type connector. See section 5.1.3 for information about balanced connection.
Mentor CX supports AES with 32, 44.1, 48 and 96 kHz sampling frequencies.
The following errors cause a failure condition:
•
Peak-to-peak signal level <320 mV
•
Incorrect AES preamble.
Word Clock, 10 MHz and 27 MHz
The word clock, 10 MHz and 27 MHz signals from the Mentor RG are transmitted as 75 Ω BNC
outputs. The maximum amplitude the unit has to cope with is 10V peak to peak. The signal type is
automatically detected and reported.
The following error causes a failure condition:
•
Peak-to-peak signal level <320 mV.
5.1.3
AES (balanced via D-type connectors)
AES signals from the Mentor RG can be transmitted as unbalanced via a 75Ω BNC output, or
balanced via a D-type connector. See section 5.1.2 for information about unbalanced connection.
Mentor CX supports AES with 32, 44.1, 48 and 96 kHz sampling frequencies.
The following errors cause a failure condition:
•
Peak-to-peak signal level <200 mV
•
Incorrect AES preamble.
5.1.4
LTC (balanced via D-type connectors)
LTC from the Mentor RG is transmitted as a balanced signal via a D-type connector.
The following errors cause a failure condition:
•
Peak-to-peak signal level <500 mV
•
Incorrect LTC sync word.
The following causes a warning condition but does not cause changeover to occur:
•
Discontinuous timecode.
