A/V equipment rentals can take up a substantial chunk of a meeting budget. In-house event planners can save thousands by buying their own, says Tracy Leaman, founder of Events to a T (eventstoatdc.com), based in Washington, D.C. Figure out how much you spend on A/V at one event and use that as your budget to buy reliable, middle-of-the-road equipment -- though what you buy depends on the size of your events, Leaman recommends four wireless lavaliere microphones, two wireless hand-held microphones, a portable sound system, a high-definition video camera with a board to control it, and a projector. Ask the company that sells the equipment to train you and your staff. As a backup (and budget allowing), have an A/V tech with extra equipment on hand at every event in case something goes wrong.
