When moving AES signals between the Black Magic de-embedder and the S-Core, what impedance change is specified?

When moving AES signals between the Black Magic de-embedder and the S-Core, what impedance change is specified?

• A. 50 ohm BNC to 75 ohm XLR
• B. 75 ohm BNC to 110 ohm XLR
• C. 110 ohm BNC to 75 ohm XLR
• D. 50 ohm BNC to 110 ohm XLR

Answer: (B)

The key idea is proper impedance matching when moving an AES signal between interfaces that use different physical connectors. AES/EBU digital audio runs as 110-ohm, balanced data, typically on XLR. In many video setups, the signal path uses 75-ohm coax with BNC connectors. So the required change is from 75-ohm BNC to 110-ohm XLR. This transition preserves signal integrity by preventing reflections and ensuring the AES signal is presented to the next device in its standard 110-ohm, balanced form. The other impedance pairings don’t align with how AES is defined or with the typical BNC/SDI vs. XLR AES pathways.
