I want to know the answer to the following question:
Did all AV receivers carry the demodulator circuits necessary for LaserDiscs, or only high-end models?
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: yes
