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.
