Radial Engineering - Presenter (Audio Presententation Mixer)

Think of the Radial Engineer Presenter as a DI box for your microphone, laptop, and media player, all in one 14-gauge steel chassis. With an XLR input, a 3.5mm TRS input, and digital conversion over USB, all of this is possible. Once you're hooked up to the Presenter, signal can be equalized and balanced so that your voice always cuts over your program material.

Dual XLR outputs take your audio to mixers and PA systems either in stereo or summed to mono, depending on how you set the device. The Presenter can be powered with a separately-available power supply, or by your laptop over USB. Please note that you can only run a laptop or a 3.5mm input at any one time.
