FM-CO13 is a wide range condenser microphone with an omni-directonal polar pattern. It is designed for unobtrusive table, ceiling, or panel-mount applications when high quality sound reinforcement is required. It’s ideal for teleconferencing, professional recording, television, and other demanding sound applications. Rubber isolators are included with each microphone for optimall mechanical isolation from the mounting surface. The FM-CO13 features a frequency response of 20 to 20,000Hz. It has a self-contained power module and operates from an external 9V to 52Vdc Phantom Power source. Output is low impedance balanced. The balanced signal appears across Pins 2 and 3, while the ground (shield) connection is Pin 1. Output is absolute polarity so that positive acoustic pressure produces positive voltage at Pin 2 in accordance with the industry standard .
