Operating the VOICE PRIORITY 
Besides wired microphone, the device can also detect the audio signal from the plug-in
module. When using the wireless microphone, position the MUSIC-WR switch to WR
(Wireless Receiver). When using other module like MP3 or Bluetooth, position the switch to
MUSIC to prevent VOICE PRIORITY from mistaking the music as microphone audio.
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 temporarily
override and lower the volume of the background music and voice could be heard more
clearly. When no microphone signal is detected, the music volume will automatically return
to its previous level.
