Digital Audio Out
“Digital Audio Out” is the first item in the left hand column; make certain that this item is highlighted, if it is not, then do so using the “Up” and “Down” navigation keys. To the right will be a list of individual choices and their current settings.
Digital Out
The first sub-submenu item is “Digital Out”. Here there are two choices, either “On” (default) or “Off”. The current selection will have a small square next to the selected entry. To change the entry, press the “Right” navigation to access the option pane and then using the “Up” and “Down” navigation keys choose either “On” or “Off” then press “Select” to indicate your choice.
The proper setting for “Digital Audio” will depend upon your system. If you have a digital processor connected to the either the S/PDIF or AES-EBU (depending upon which module you have installed) then you will want to select “On”. If the digital audio output is unused, then set this output to “Off” in order to reduce any emissions that would result from an terminated digital connection.
Dolby Digital Out
The second sub-submenu item is Dolby Digital. Here there are two choices, either “Dolby Digital” or “Dolby Digital > PCM”. Using the methods defined previously, navigate and select the
configuration that is correct for your system. The decision to use either “Dolby Digital” or “Dolby Digital > PCM” will depend upon the capabilities of your digital processor. If your processor can accept Dolby Digital bit-streams then select “Dolby Digital” if your processor is only capable of PCM, then select “Dolby Digital
>PCM”. If uncertain, contact the manufacturer of your digital processor.
DTS Out
The third sub-submenu item is for DTS. Here, like with Dolby Digital there are two choices, either “DTS” or “DTS > PCM”. Again, the correct choice will depend upon the capabilities of your digital processor. Using the navigation keys, select the appropriate choice for your systems capabilities.
Linear PCM Out
The fourth sub-submenu item is for PCM. Here, like in the previous examples there are two choices, either “Down Sample On” or “Down Sample Off”. The proper choice depends upon the capabilities of your digital processor. If your processor can handle medium speed digital audio sample rates (like 88.2 kS/s or 96 kS/s) then select “Down Sample Off”. If your processor is only capable of low speed digital audio sample rates (44.1 kS/s or 48 kS/s) then select “Down Sample On”. It should be noted that this control will also affect ‘Packed PCM’ material like MLP. The disc content and the protection scheme used by the disc will also affect the available data for PCM or packed PCM material. If copy protection is invoked on the disc, then the data rate will be reduced to low speed (either 44.1 kS/s or 48 kS/s) with a maximum word length of 16 bits, regardless of the setting you choose for the “Down Sample” option. High speed digital audio (176.4 kS/s and 192 kS/s) is not available from the digital audio output regardless of its presence on the disc. If playing a disc with high speed material, the digital audio output (either S/PDIF or AES-EBU) will process the data to either medium or low speed depending upon copy protection and the setting used in this sub-submenu choice, the lower of the two will prevail.
