Whirlwind AES-SP1X2 AES/EBU Splitter

The AES-SP1X2 delivers two identical AES/EBU signals from a single stream, passively. That matters on a digital feed, where a lazy parallel split degrades the eye pattern and the receiver starts dropping lock rather than simply sounding quieter.

The design uses a dual secondary transformer on the input and a separate isolation transformer for each output. With three transformers in the circuit it keeps data integrity high and gives a large amount of isolation between the two outputs.
