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.
