Microphones TableMIC connect to Vaddio products via EasyMIC ports to transmit professional-quality sound to a computer system for excellent conference call quality. Designed to reduce distracting noises that occur in a conference room, the all-metal base of the TableMIC and special feet minimize noise from table vibrations that other microphones may pick up. At the top of the TableMIC is a capacitive touch control panel for silent operation. The ability to enable and disable button functions during setup can further simplify the end user's experience with video conferencing. One TableMIC microphone with 360-degree coverage from three unidirectional condenser microphone elements provides excellent coverage for most conference rooms. Each of the three unidirectional cardioid microphone elements in the microphone is equipped with built-in echo cancellation and digital signal processing (DSP), including equalization, filtering, and automatic gain control (AGC). The DSP in a companion product, such as the Vaddio AV Bridge MATRIX PRO or EasyUSB Mixer/Amp, provides AEC reference from the far end and applies it to the individual microphone elements, ensuring crystal-clear conference calls at both ends of the conversation. Plug-and-play installation is straightforward: simply connect a standard Cat-5 cable between the TableMIC and Vaddio equipment compatible with EasyMIC. Power, control, and audio are transmitted over a single cable. The TableMIC supports cables up to 100 feet (30 meters) between the microphone and EasyMIC ports.
