•
Press the left/right ARROW buttons to select the channel to be adjusted.
•
Press the up/down ARROW buttons to raise or lower the volume of the selected channel in
0.5dB increments.
•
Press the SELECT button to confirm the settings and return to the Audio Setup Page.
Channel trim is generally not required since most A/V receivers have the capability to adjust
channel trim and compensate for speaker sensitivity differences. However if your receiver does
not have such functions, you may adjust channel trim on the DVD player. For most accurate
results, it is recommended that you use test tones from a calibration disc, such as AVIA Guide
to Home Theater, and a SPL (Sound Pressure Level) meter.
7. Audio Delay: To add delay to analog or PCM digital audio output. If you experience
audio/video synchronization problem, you may use this option to add a slight delay to the audio
so it is in-sync with video.
•
Press the left/right ARROW buttons to adjust delay. The audio delay can be adjusted in
10ms steps.
•
Audio delay does not apply to raw bit stream digital audio output.
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
- 6 channels. This option is recommended when connecting the HDMI output to an A/V
receiver or processor with HDMI 1.1 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.
