The Presenter combines a microphone preamp and a USB program input to create the ultimate interface for any presentation, from school lectures to corporate audio. An XLR mic input allows you to connect a podium microphone and power it via phantom power. The mic signal can then be adjusted using three EQ controls: a high-pass filter rolls off excessive low end, and Low and High knobs allow you to tailor the frequency response. A program input level controls the volume of the USB input or the 3.5mm jack on the front of the unit, so you can connect the outputs of your laptop, smartphone, or MP3 player and blend it with the signal from the microphone. XLR outputs provide balanced feeds for a set of powered speakers, providing an all-in-one portable solution for any speaking engagement.
