The vaddio 999-85150-000 CeilingMIC Microphone (Black) delivers professional audio quality into your PC system for superior conferencing experiences when connected to Vaddio products with EasyMIC ports. The CeilingMIC complements most interiors with its sleek design featuring smooth lines and quality acoustical fabric wrap. This overhead microphone is a more economical alternative to a custom installation. Compared to table microphones, ceiling-mounted microphones create a clean look in your conference room or meeting space and eliminate table clutter. Vaddio's CeilingMIC is ideal for drop tile ceilings and open-ceiling environments as well. With full 360-degree pickup coverage, one CeilingMIC provides excellent coverage for an average size meeting room table. For larger tables, a second CeilingMIC provides additional coverage. Each CeilingMIC unit delivers the performance of three microphone elements built into a single pendant hanging enclosure. Each unidirectional cardioid microphone element is equipped with integrated 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 an AEC reference from far end and applies it to individual mic elements, so conference calls are crystal clear on both ends of the conversation. With its plug-and-play design, installation is as simple as connecting a Cat-5 cable between the CeilingMIC microphone interface box and the EasyMic-compatible Vaddio equipment. Power, control, and audio are all incorporated into the single cable. The CeilingMIC supports lengths of up to 100 feet of Cat-5 cable between its interface box and EasyMIC ports. In addition, its lightweight, simplified ceiling box means faster, easier installations. The CeilingMIC pendant includes a 36-inch adjustable drop cable and with a standard RJ45 jack connection, the pendant can be extended to a total length of 15 ft (5 meters) from the interface box.
