Connecting the Audio Inputs,
To Connect the Audio Inputs
Do as follows to connect the audio inputs:
1. For digital channels 1 and 2 connect the audio input to the Digital Audio In
connector.
Hint: For digital audio connections, use a coaxial cable designed for 75-ohm
AES-3id.
2. For analog channels 1 and 2 do as follows:
Spring Cage Plug
Connector
3. For channels 3 and 4 connect the analog or digital audio input to the Ana/Dig
Audio In 3 & 4 part of the terminal block connector. The input type of channels 3
and 4 is set up in the GUI.
Hint: For digital audio connections, use a balanced cable designed for 110-ohm
AES/EBU digital audio or a coaxial cable designed for 75-ohm AES-3id. Use a
high-quality balanced audio cable for the analog inputs.
If you have many or heavy audio cables connected to the D9040 Encoder, you
may need to suspend the cables in your rack to prevent unnecessary mechanical
stress on the audio connector.
4. If relevant, use the Digital Out pins of channels 3 and/or 4 to synchronize
external equipment to a reference clock. The reference clock is locked to the
video.
