Layout and labelling of the multi cable connector.
In addition to the connectors for analog signals there are five XLR connectors for
digital signals, two inputs ("AES-EBU In1" and "AES-EBU In2"), two outputs
("AES-EBU Out1" and "AES-EBU Out2") as well as one connector for
synchronizing ("AES-EBU Sync").
Before you perform measurements with the Digigram audio interface board,
settings need to be made in the mixer program of the audio board. The mixer
program can be opened from the Windows NT Start menu
Start|Digigram|DigiMix . The mixer dialog is shown in
Figure 4.5
. Here,
select whether the digital AES-EBU input connections or the analog inputs shall
be used, then click on the corresponding buttons in the “Record Source” field.
In the field below – titled “Clock Select” - the settings for the clock can be
chosen
Figure 4.6
, There are three kinds of synchronizing your digital
signals. Either the Word Clock Input, the AES Sync Input or the Digital Input 1
can be chosen.
It is not necessary to change the settings of the input gain settings since OPERA™
usually works fine with the default settings.
Note:
The Digigram Audio Interface Board is designed as a dual stereo
board. Consequently, two mixer displays can be called, each taking
effect of one stereo channel. To switch between the two mixer
displays, select either one from the menu option "Mixer".
