8 SETTINGS (Ctd.)
•
LPCM – Digital audio output via HDMI will be in the multi-channel Linear PCM
format. When this option is selected, compressed audio bit streams will be
decoded by the player. This setting is recommended when connecting the HDMI
output directly to a TV or to a receiver without compatible audio decoding
capabilities.
•
Bitstream – Digital audio output via HDMI will be in bitstream format. This option
is recommended when connecting the HDMI output to an A/V receiver or processor
that supports compatible audio decoding, such as Dolby TrueHD and DTS-HD
Master Audio.
•
Off – No digital audio output via HDMI.
3. Coaxial/Optical Output: Allows you to set the audio format and the upper sample
rate limit for coaxial/optical (S/PDIF) digital outputs. The upper sample rate limit is
used to decide whether the player will down-sample audio (the player does not up-
sample audio to higher sample rates).
•
48k LPCM – Forces down-mixed 2-channel, linear PCM (LPCM) digital audio
format, and sets the maximum sample rate to 48kHz. This is supported by most
receivers/amplifiers.
•
96k LPCM – Forces down-mixed 2-channel, linear PCM (LPCM) digital audio
format and sets the maximum sample rate to 96kHz. It can result in better audio
quality but ensure the receiver/amplifier can support it.
•
192k LPCM – Forces down-mixed 2-channel, linear PCM (LPCM) digital audio
format and sets the maximum sample rate to 192kHz. It can result in better audio
quality but ensure the receiver/amplifier can support it.
•
Bitstream – Passes audio as compressed bitstream format to the
receiver/amplifier. Choose this setting if your receiver/amplifier is capable of
decoding Dolby Digital and/or DTS.
NOTE
If you use HDMI to connect audio to an HDMI
A/V receiver or audio processor, it is important
that you choose 720p or higher HDMI output
resolution when playing high resolution audio
content (DVD-Audio, SACD, Dolby TrueHD and
DTS-HD Master Audio). According to the HDMI
specification, the bandwidth available for audio is
proportional to the total bandwidth used by video.
At 480p/576p resolution, the HDMI specification
can only support 2 channels of audio with high
sample rate (up to 192kHz), or 8 channels of
audio with standard sample rate (up to
48kHz). If
you play high resolution audio content at the
480p/576p resolution, you may get
reduced
audio resolution, incomplete audio channels, or
even no audio/video output at all.
Choosing a higher output resolution such as
720p or above allows enough bandwidth for all
high sample rate audio channels.
NOTE
Due to copyright restrictions and bandwidth
limitations, SACD audio cannot be sent through
the coaxial/optical audio output, and the high
resolution audio on DVD-Audio and Blu-ray discs
will be sent out at reduced resolution.
