System Details

The Microflex Complete digital conference system is ideal for any group that holds formal meetings -- from small city councils to corporate boardrooms to multi-lingual international conferences with thousands of participants. It gives you complete control over audio, the agenda, voting, support documents, information display, and interpretation, making even large conferences efficient and productive.

Its intuitive user interface allows meeting participants to easily control their microphone, vote, view the agenda, and select interpretation channels. Integrated NFC card technology allows meeting participants to be identified by name without additional software or feature licenses.

With a selection of portable, flush-mount, and modular conference units, Microflex Complete fits into any room design. Industry-standard Shure Microflex® gooseneck microphones (available with single or dual flexible sections) include CommShield® Technology for RF immunity and interchangeable microphone elements for excellent sound quality.
