Marcus will prepare a presentation for your industry showcasing the benefits and opportunities to your field in social media. He'll be using a MacBook for slides. He'll bring a VGA and HDMI adaptor for your AV system. Audio is not usually required. For any group more than 35 people, he needs a microphone. Please be sure that you've tested it on all areas of the stage for volume and for feedback. Slides will only run from his laptop.
