Pioneer CLD-D604 No AC-3 output
Hello, I have a CLD-D604. The AC-3 output does not seem to be outputting a signal. Connection is..... CLD-D604 output --> Yamaha APD-1 RF > AC-3 demodulaor input --> Denon AVR-3805. Tried coax and optical. However I observed no light from the optical cable. Which leads me to believe either there is not an output from the Pioneer or the Yamaha is faulty. What test(s) can I perform to the Pioneer to see if there is indeed an output from AC-3 out? BTW, I used laser disks that are encoded with Dolby surround for the test.
Thank you in advance for your help.
