Presenter Audio Presentation Mixer
Presentation Mixer & USB Interface
The Presenter? is a compact mixer that combines a microphone preamp and a USB program input to create the ultimate interface for any presentation, from school lectures to corporate audio.
Mic preamp with phantom power & EQ controls
USB connection for high quality audio playback from a laptop
5mm stereo input to connect smartphones & mobile devices
Balanced outputs to feed a pair of powered speakers or a PA
Own the podium
The Presenter replaces typical audio mixers that include numerous complicated controls and knobs that rarely get used, instead opting for a simplified and intuitive layout that allows anyone to operate it and achieve high quality sound with minimal effort. An XLR mic input allows you to connect a podium microphone and provide it with phantom power. The mic signal can then be adjusted using three powerful EQ controls 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, which allows you to 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, making it an all-in-one portable solution for any speaking engagement.
Presenter Specifications
The Presenter provides a simple but robust mixer that makes setup for any event or presentation easy. A microphone preamp allows a dynamic or condenser mic to be connected and quickly feed a pair of powered speakers via the XLR outputs. Tone controls and a low-cut filter help optimize the sound of the microphone, while additional inputs are available to use a playback source alongside the mic, such as a smartphone or tablet. These can be connected using a 3.5mm input, which includes a level control. A USB input provides power for the Presenter and also allows for playback of digital audio files from a laptop computer.
