PDR100 Audio
The PDR100 supports both analog and serial digital embedded (625 only)
audio inputs and outputs, depending on which boards are installed your the
PDR100 system. Audio in the PDR100 is routed using the EISA bus with data
flow controlled by a real time controller and the audio interface card. The
analog audio card is capable of converting four channels of analog audio to
digital audio (and vice versa) using 16-bit/48kHz conversion. The input and
output data flow to the card via the EISA bus, with sample clocks coming from
a video interface card, such as the analog composite board or the SDI board.
However, the analog audio card can only have one clock operating at a time. If
the card is used as an input device, it must have the clock that originates on the
video board associated with the audio.
Analog Audio Input
To open the Analog Audio Input dialog box, select Audio Input from the
configuration tree, and then click or double-click an analog audio name from
the list, such as Analog-InA-J8. The dialog box appears, as shown in Figure 34.

• Name allows you to change the signal name—from Analog-InA-J8 to Audio
One, for example. Signal names can be up to 30 characters long, and can
include spaces. The window title bar name and the configuration tree name
automatically change as you enter the new name. To return a renamed signal
to the default, delete all the characters in the text field, and press Enter.
