Voice Priority operation
Voice Priority operation is only necessary when CD/DVD/MP3 is playing.
When the Voice Priority switch is ON, the ducking function will be activated. While the
music is playing, a voice input from either a Wired or Wireless Microphone will temporary
override and turn down the volume of the background music and voice could be heard
clearly.
Background music will return to its original setting when no audio input is entering the
microphone for a certain time. However, if the microphone is not switch off, the reentering
of music into the microphone will also activate the voice priority function. So, Voice
priority is best operated using microphones with on / off switch.
However, in an aerobic operation, Voice Priority should NOT be activated !
