The Revoluto integrated microphone units expand the versatile range of microphones available for use with the MCS-Digital conferencing system. These units can be concealed in the table and opened out as required. This is made possible by the patented Revoluto technology, which removes the need for gooseneck microphones. Featuring a high quality Nextel® dark-black coating, the units can be integrated aesthetically into desktops of varying materials. If required, the cover surface can be finished by the customer with a special veneer to match the table surface, allowing the technology to be integrated discreetly in any conference table.
