The easy to use Rolls DU30B Audio Ducker with Microphone Preamp is designed for a small club, restaurant, or store where voice paging is required to be heard over background music. The unit inputs the music source via a pair of RCA inputs, while the microphone is connected via an XLR input that can supply +12V phantom power.
If another source other than voice needs to control the ducking, that can be brought into the unit on additional RCA jacks. The microphone input has a pad in case the microphone being used has a high output. The sensitivity control of the DU30b sets the threshold at which the microphone will duck the music and a mic level knob controls the volume of the microphone input.
