Working with Audio Audio Mixer Controls
Audio Mixer Controls
The default settings in the Audio Mixer have all channels at 0 (zero) db. The MIX
channel, however, is set at its mid-way point. Channel A is selected, as indicated by its
highlighting.
The following tables explain how to operate the Audio Mixer controls from the MXPro
keyboard.
Using Background Audio
MXPro’s Input 4 has a special feature — you can use it for background music. To con-
trol the level of the music, use the Background Music slider in the Audio Mixer. Use the
keyboard controls shown in the preceding table to adjust the audio level.
Depending on how you set things up, the CURRENT source transitions to the NEXT
source and the background music plays uninterrupted between them. The audio from
the CURRENT and NEXT sources normally follows the video transitions — for example,
if you set up a dissolve transition, audio from the CURRENT source fades away, then
the audio from the NEXT source fades in.
