Outputs
Regardless of the type of codec used to store the movie’s audio track onto the disc, audio data is always
stored on a disc in a digital format. The BD player therefore has digital audio outputs, so that the digital
audio soundtracks on the disc can be sent straight to a surround-sound receiver, without any loss in
audio quality.
Not all surround-sound receivers are capable of playing back all of the digital audio codecs listed above.
In addition, some surround sound receivers can play back PCM data, but the data must be sent to the
receiver at a slower rate than what is stored on the Blu-Ray disc.
Because of this, an understanding of your surround-sound receiver’s capabilities is required in order
to properly set up the digital audio outputs of the BD player.
Now that the various types of digital audio codecs have been explained, the next few menu items will be
described in further detail.
5.3.2 PCM Downsampling
You can use this menu item to tell the BD player whether your surround receiver can handle high-
bitrate PCM signals over COAXIAL.
This menu item has no effect if you are connected to your TV or surround receiver over HDMI.
To inform the BD player of your surround sound receiver’s PCM capabilities, first make sure that the
Audio setup menu item is highlighted:
PCM Downsampling 48 kHz
Then, press the right arrow key ( ) on the remote to make the Digital Audio Options Menu appear.
Press the up/down arrow keys ( ) on the remote until the
