The TRIO I/O interface is based on Vaddio's SmartMIC technology, a simple and less expensive approach to adding live audio conferencing to room designs. As an interface between the TRIO Mics and any professional audio mixer, internal DSP and echo cancellation can now be integrated into any manufacturers audio mixing system.  Each TRIO SmartMIC is equipped with an array of three electric condenser microphones positioned to form a 360-degree pickup pattern. This unique technology is based on the microphones ability to actively manage the rooms live audio for gain, gating and echo cancellation. Once detected, the microphone will adjust and mix down to a single output. Because the intelligence is inside the microphone, any mixer can now be used in a live collaboration application for audio conferencing and achieve outstanding results.     The TRIO I/O interface device allows the connection of up to three SmartMICs and because each input is effectively running three microphones on three different channels, users can technically run 12 microphones all with independent echo cancellation and internal DSP. For installations requiring more than 12 SmartMICs, just add an additional TRIO MIC I/O for 12 more channels.
