Audio Mixer Controls
The default setting in the Audio Mixer for all channels is 0 (zero) dB. The default set-
ting for the Background Mix level is no mix.
The following tables explain how to operate the Audio Mixer controls from the
MXProDV keyboard.
Using Background Audio
Any audio input can be used as the source for background audio. Use the Route
menu to select a source and press
SHIFT+NEXT/COLOR to access the background audio
channel. To control 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.
