A. Dual Mono: To choose the output for Dolby Digital discs encoded with two independent
audio channels, such as bilingual programs. The options are:
• Stereo – Stereo output
• L-Mono – Left channel output to both Left and Right speakers.
• R-Mono – Right channel output to both Left and Right speakers.
• Mix Mono – Left and Right channels mixed to both Left and Right speakers.
B. Dynamic: To set the Dynamic Range Compression (DRC). DRC can smooth out the sonic
peaks and valleys common with wide-range digital audio. Increasing DRC may make low
level audio more audible during low-level listening. Decreasing or turning off DRC restores
the sonic energy present in the original recording.
8. HDMI Audio: To select digital audio output from the HDMI port. The options are:
• LPCM – Digital audio output via HDMI will be multi-channel Linear PCM format. The Down-
mix setting in the “Speaker Setup Page” will affect whether and how multi-channel audio
content will be down-mixed to stereo. When this option is selected, compressed audio bit
streams will decoded by the DVD player. This setting is recommended when connecting
the HDMI output directly to a TV.
• Auto – Digital audio output via HDMI will be the same as the digital coaxial/optical audio
output for CD, Dolby Digital and DTS audio signals. For high resolution stereo or multi-
channel audio contents such as DVD-Audio and Super Audio CD, the DVD player will send
multi-channel PCM audio signals with the highest available sample frequency and bit
numbers. Depending on the original audio content, the format could be 44.1kHz - 192kHz, 2
- 8 channels. This option is recommended when connecting the HDMI output to an A/V
receiver or processor with HDMI v1.1 or above audio capabilities.
• 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
recommended that you choose 720p or higher HDMI output resolution when playing high
resolution audio content (DVD-Audio and SACD). 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).
Depending on the capability of your A/V receiver or audio processor, if you play high
resolution audio content at 480p/576p resolution, you may get reduced audio resolution,
incomplete audio channels, or even no audio/video output at all. Choosing a high HDMI
output resolution such as 720p or 1080i allows enough bandwidth for all high sample rate
audio channels.
9. 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. If you use the multi-channel analog output or a receiver that supports
HDMI v1.1 to listen to SACD, please select this option.
• DSD – SACD DSD data is output over HDMI without any conversion. A receiver that
supports HDMI v1.2a with DSD over HDMI is required. When this option is selected, the
DVD player does not decode SACD audio, and its analog audio output is muted. Instead,
the receiver is responsible for decoding the DSD data stream it receives over HDMI.
