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. 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:
x LPCM – Forces down-mixed 2-channel digital audio output. Choose this setting if your
receiver/amplifier only supports stereo digital (PCM) audio.
x 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.
4. 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:
x 48K – Supported by most equipment.
x 96K – Allows a higher sampling rate and frequency response. It can result in better audio
quality. Ensure that the receiver/amplifier can support it.
x 192K (default) – Allows the highest sampling rate and frequency response. It can result in the
best audio quality. Ensure that the receiver/amplifier can support it.
NOTE
On the BD32, the “LPCM Rate Limit” can also affect the analog audio performance. Setting to
“192K” may help to get the best analog audio quality.
5. SACD Output: To select audio output format for SACD. The options are:
x 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.
x 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.
6. HDCD Decoding: To set the audio decoding option for HDCD (High Definition Compatible Digital)
discs. The options are:
x On – HDCD is decoded by the player. You can enjoy expanded dynamic range and improved
audio resolution.

x Off – HDCD is treated as regular CD. This is useful when the player is connected to an
HDCD-capable A/V receiver via a digital audio output link (Coaxial, Optical, or HDMI) so the
A/V receiver can perform HDCD decoding.
NOTE
If your receiver is capable of HDCD decoding, it is recommended to set the “HDCD
Decoding” to “Off” on the BD32, otherwise you might occasionally hear pop or crackle
sounds during the HDCD playback.
