5.9 Audio Modules panel
The XVP-3901 has two on-board sockets for optional audio modules. The supported modules are:
•
MOD-DOLBY-DEC-2
Dolby E/Digital (AC-3) decoder
•
MOD-LA-DUP-701
Linear Acoustic upMAX
tm
•
MOD-DOLBY-ENC-D-2 Dolby Digital (AC-3) encoder
•
MOD-DOLBY-ENC-E
Dolby E encoder
•
MOD-LA-ALC-X-YYY
Automatic Loudness Control using the AeroMAX
tm
licensed technology by Linear Acoustic
•
MOD-JA-ALC-X-YYY
Automatic Loudness Control using the Level Magic
tm
licensed technology by Jünger Audio
Any of these modules can be inserted in either socket 1 or 2. When a module is installed
in one of these sockets, its controls will appear in the appropriate tab in this panel.
See Section 6 beginning on page 109 for detailed descriptions of all of the available
modules and their associated control panels.

tm
(ALC) modules are located at the input of the audio processing path, as shown in this block diagram of the
XVP-3901 audio processing section. If both modules are installed, the Dolby decoder module is located before the
upmix or ALC
modules in the audio processing path, to allow the decoded channels to be upmixed. The Dolby-
E/Digital encoder modules are located at the end of the audio processing path.
The output channels of the above modules are always fixed and depend only on the module socket number in which it
is inserted. The outputs for module 1 will always be in the range 17 to 24. The output for module 2 will always be in
the range 25 to 32. Refer to the table below for a quick overview of the output channels versus the installed modules
and their module position:
Installed Module
Output channels when in Module #1
Output channels when in Module #2
MOD-DOLBY-DEC-2
17-24
25-32
MOD-LA-DUP-701
17-22
25-30
MOD-DOLBY-ENC-D-2
17-18
25-26
MOD-DOLBY-ENC-E
17-18
25-26
MOD-LA-ALC-X-YYY
17-24 (
depending on number of channels
)
25-32 (
depending on number of channels
)
MOD-JA-ALC-X-YYY
17-24 (
depending on number of channels
)
25-32 (
depending on number of channels
)
It must be noted that the MOD-LA-DUP-701 has only 6 outputs and the MOD-DOLBY-ENC-D-2/E has only 2 outputs.
In these cases, only the first 6 or 2 channels are used. The MOD-LA-ALC-X-YYY and MOD-JA-ALC-X-YYY modules
may have from 2 to 8 outputs depending on the model used.
The processing delay for all MOD-LA-ALC-X-YYY and MOD-JA-ALC-X-YYY modules is ¼ of a video frame. To
compensate for this processing delay, the user must increase the processing delay of the card by +1 frame.
This additional processing delay must be added manually in the Video Output panel under the Timing tab.
