5.3 Audio
5.3.1 PCM Down sampling: select right bitrate for PCM signal to ensure your SPDIF
receiver can handle it correctly. It's no effect for HDMI digital audio output.
5.3.2 Digital Output:
If you only have two speakers, set PCM stereo.
If you connect the receiver with more than two speakers, please refer to below tables:
5.3.3 Dynamic Range Control: means that you can allow the BD player to make
the loud parts of a movie's sound track quieter than they would be in the theatre,
without making the dialog of the actors any quieter. (Analog audio output and digital
output should be set to PCM or Bitstream Mixed).
5.3.4 Stereo Downmix: Select Auto. Stereo (LoRo) or Surround Enclosed (LtRt).
Note: In order to get the correct primary and secondary mixed audio at the Audio Out
FL and FR, please set HDMI to 2ch-PCM in the SETUP menu (Settings>Audio>Digital
Output>PCM Stereo) or connect a HDMI cable to your TV.
