I want to know the answer to the following question:
What did the Onkyo outboard demodulator covert the RF AC-2 signal to?
All the background I'm provided with is that "In the mid to late 1990s many higher-end AV receivers included the demodulator circuit specifically for the LaserDisc players RF modulated Dolby Digital AC-3 signal.". Is that enough to answer the question?
Answer: no
