The easy-to-use Rolls DU30b Audio Ducker with Microphone Preamp is designed for small clubs, restaurants, or stores 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.
