Selecting your analog audio source

If you are performing an analog capture in Adobe Premiere Pro, you must define the audio source from which you want to capture material. Your audio source must match your audio input (that is, where you have connected the light blue connector labeled TO AUDIO CARD IN on your RT.X breakout cable). For example, if you plugged the TO AUDIO CARD IN connector into the Line-In jack (or corresponding jack) on your sound card, choose Line-In from the Analog Audio Source list.

For details on how to connect your RT.X breakout cable, see the manual for your Matrox RT.X system.

To select the audio source from which you want to capture material:

1	Choose Project > Project Settings > Capture > A/V Inputs.
2	From the Analog Audio Source list, select the audio source that matches your audio input. All supported audio sources will appear on the list, but in most cases the recommended source will be the default.
	Important If your audio input connection does not appear in the Analog Audio Source list, you must unplug the TO AUDIO CARD IN connector on your RT.X breakout cable and connect it to an audio input on your sound card that appears in the list.
3	Click OK to return to the Project Settings dialog box.

If your analog audio source appears with an * beside it in the list, your sound card does not have matching audio inputs and outputs. In this case, choose the audio source with an * that matches your audio input, make sure that your source is playing back audio, and click Advanced Settings. In the Advanced Settings dialog box, select an Analog Audio Passthrough. If you can hear audio, then you’ve selected the correct analog audio source and passthrough. If you can’t hear audio, try selecting a different analog audio source and/or passthrough.
