The Philips DPM8900 is a portable conference recording kit housed in a carry briefcase, built for recording meetings, hearings or interviews where multiple people around a table need to be picked up clearly. It includes 4 boundary layer microphones — flat, table-mounted mics designed to capture voices from across a room without a forest of individual handheld or lapel mics — connected to a central recording unit. This kind of kit suits legal, corporate governance, and minute-taking use cases where an accurate, easily-transcribable audio record of a multi-person discussion is needed, and the briefcase form factor lets it be set up in any meeting room rather than requiring a permanently wired installation.
