Presenter± microphone l a p t o p mixer
The Presenter™ is a simple but robust mixer that makes the audio setup for any event
or presentation easy. A high quality microphone preamp with switchable phantom power
allows any microphone to be connected, with dual tone controls and a low-cut lter to help
optimize the sound of the mic in the room. XLR outputs are provided to feed a pair of powered
PA speakers, with a ground lift switch to eliminate buzz and hum from ground loops. The
Presenter is powered via USB, which also allows it to be connected to a laptop computer
for high-quality digital audio playback. A program level knob provides control over the output
from the laptop, and a 3.5mm input allows a smartphone or tablet to be connected as an
alternate playback source.

Application
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 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, 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.
