NOTE: Since the Deep Color feature is OPTIONAL and may not be supported by all TVs, enabling Deep Color while connected to
a TV without this feature may result in no effect or no video. At this time, no disc is encoded with Deep Color. Enabling Deep Color
will not magically make colors richer, but will help preserve the maximum precision as a result of video processing and picture control
adjustment. Dithering is a technique to improve the image color depth with limited color quantization.
Audio Format Setup
The “Audio Format Setup” section of the
Setup Menu system allows you to congure
preferences for audio output formats. As the
UMT is a transport capable of outputting the
highest quality audio, the user is cautioned
against changing any of these menu items.
The menu items in this section are:
1. Secondary Audio: To set the Secondary
Audio Program mixing option. Some
Blu-ray Discs contain a secondary
audio and video program, such as the
director’s commentary. Some Bluray
Discs have a sound effect when you
make menu choices. This Setup Menu
item allows you to decide whether to
mix the Secondary Audio Program and
menu clicking sound into the primary
audio. The options are:
• On – The Secondary Audio Program
and menu clicking sound are mixed
into the primary audio. Usually this
will cause the primary audio volume to be slightly reduced and should be avoided.
• Off– The Secondary Audio Program and menu clicking sound are not mixed into the primary audio and you cannot hear the
secondary audio or menu clicking sound. This setting preserves the highest possible audio quality for the primary audio.
2. HDMI Audio: To select digital audio output format from the HDMI port. The options are:
• Auto (default) – The player checks with the device connecting to HDMI output to automatically determine which audio format to
use.
• 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. This process bypasses the MSB processing.
• 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.Thisisrecommended.
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 specication, the bandwidth available for audio is proportional to the total bandwidth used by video. At 480p/576p
resolution, the HDMI specication 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 Surround Output: To set the output format for the Surround 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. This option should NOT be selected. The UMT digital outputs
always output LPCM. This option is for the coaxial and optical surround output only.
• Bitstream– Passes audio as compressed bitstream format to the receiver/amplier. Choose this setting if your receiver/amplier
is capable of decoding Dolby Digital and/or DTS. This output will work but bypasses the MSB processing and should only be
used for movies.
4. LPCM Rate Limit: This menu item does NOT change the sample rate of the digital audio outputs.
NOTE: Output sample rate is set using the small toggle switch on the rear of the unit only when upsampling is enabled.
