Operating Instructions
6.3Audio Menu Volume Control
This menu item is used to activate or deactivate the volume control buttons on the remote control. If the digital receiver is connected to the display by HDMI(DVI), the volume control is automatically set to maximum and deactivated. The volume control does not function on SD output to a VCR or DVD recorder.
Audio Delay Time
Some types of displays may have different delay times in displaying pictures, which may cause a slight problem with lip sync. This means that the audio is not heard at the same time as the person is speaking.
This feature allows you to select a time delay suitable for the video display to synchronise with the audio. The delay time depends on which choice appears to provide best performance of lip sync on your display device.
MPEG Audio Level
The MPEG audio level can be adjusted from
Audio Mode Priority
The Audio Mode Priority is used to choose the preferred sound track when both Dolby Digital (Dolby D) audio and MPEG audio are received with the program. Use
the cursor 
to select your choice. You may select any soundtrack channel by channel, regardless of the audio mode setting made in this menu.
If the default Audio Mode is Dolby D audio, and the input signal contains only MPEG audio, the default mode will change to MPEG automatically. If the Audio Mode is set to Dolby D audio, the digital receiver will automatically select the Dolby D audio soundtrack when it is available.
We recommend Dolby Digital audio selection if you will be connecting your receiver to a TV or A/V receiver that can decode Dolby Digital audio (look for the 
logo) or Dolby Pro Logic II (look for the 
logo).
Digital Audio
This function sets the output format of the digital audio from the S/PDIF terminal. “Auto” outputs the Dolby Digital audio as a digital bitstream in the same format as broadcast, and outputs MPEG audio as PCM stereo. Dolby Digital audio can be broadcast from 2.0 stereo to 5.1 surround sound.
“PCM” outputs Dolby Digital audio and MPEG audio as PCM stereo.
