Setup Menu Options
2. HDMI Audio: To select digital audio output format from the
HDMI port. The options are:
• LPCM – Digital audio output via HDMI will be 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
advanced 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 advanced audio decoding, such as
Dolby TrueHD and DTS-HD Master Audio.
• Off – No digital audio output via HDMI.
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 (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.
3. SACD Output: To select audio output format for SACD. The
options are:
• PCM – SACD Direct Stream Digital (DSD) data is
converted into multi-channel, high resolution PCM data.
The converted PCM data is then output through HDMI
or the internal DAC (Digital to Analog Converter) for
the analog audio output ports. If you use a receiver that
supports HDMI v1.1 to listen to SACD, please select this
option. You may also want to select this option if you
prefer the sound quality of the DSD-to-PCM conversion.
• DSD – SACD DSD data is output over HDMI without any
conversion. For the analog audio outputs, DSD data is
converted into analog signal directly by the internal DAC.
If you use a receiver that supports HDMI v1.2a with DSD
over HDMI, or you prefer the sound quality of straight
DSD to analog, please select this option.
4. Coaxial/Optical Output: To set the output format for the
coaxial/optical digital audio output for use with Dolby Digital
and DTS-compatible receivers. The options are:
• LPCM – Forces down-mixed 2-channel digital audio
output. Choose this setting if your receiver/amplifier only
supports stereo digital (PCM) audio.
• 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.
5. LPCM Rate Limit: To set the maximum Linear PCM output
frequency for the coaxial/optical digital output. This menu
item is intended to ensure that the audio output is compatible
with equipment that cannot support high sample rates. It sets
an upper limit to decide whether the player shall down-sample
audio. The player does not up-sample audio to higher sample
rates. The options are:
• 48K – Supported by most equipment.
• 96K – Allows a higher sampling rate and frequency
response. It can result in better audio quality. Ensure that
the receiver/amplifier can support it.
• 192K – Allows the highest sampling rate and frequency
response. It can result in the best audio quality. Ensure that
the receiver/amplifier can support it.
