Press & Hold
The player status is indicated by a small backlit LCD screen to the immediate left of the transport buttons.
For MIC channels priority, increasing the VOX control will cause the level of playback through the LINE or
USB/FM/AUX channels will be reduced when speaking into MIC1 or MIC2. Adjust this control to achieve the
required amount of "ducking" of the other channels when MIC channels are used.
