Notes:
1. In the case of digital audio connections, note that the GND (ground) connection is common to two
audio circuits as opposed to the connections used for standard analog audio circuits. In the case of
digital audio circuits then, a single XLR connector supplies two (2) each audio circuits instead of a
single audio circuit in the case of standard analog audio connections.
2. Due to the variety of audio connection options available, either of two existing analog audio
connections may be connected to J13 (digital audio). The circular panel pin out will change
depending on which existing audio connection is used. See below for additional details.
Strata TX Digital and Analog Audio Options
Introduction
Due to the unique design of the Strata TX digital encoder circuit, a number of digital and analog audio
input options may be accommodated. This brief memorandum describes the provisioning and use of
these audio circuits.
Digital Encoder Audio Options
The current Strata TX system supports the following MPEG encoder audio input signals:
•
Analog audio
•
AES-EBU digital audio
•
SDI Embedded digital audio
Note:
SDI embedded digital audio is “embedded” within the SDI digital signal when the SDI video
option is employed, i.e., an SDI video + audio signal is connected to the TCU or TXU “Signal Input”
BNC connector. In this case the digital audio signals are not connected to the encoder via the circular
panel audio connector.
