Adjusting and monitoring audio levels
Click the speaker in the activity pane at the top of the Catalyst Browse window to display audio controls.
Drag the Master Volume fader to increase or decrease audio levels. During preview, the meters allow you to monitor the level of each audio channel.
If you want to choose which audio channels will be played, you can use the Channel Routing check boxes. In the example above, the 1st, 3rd, and 5th channels are played through the left speaker and the 2nd, 4th, and 6th channels are played through the right speaker.
Catalyst Browse supports only stereo output devices.
