Denon Professional today launched something it’s calling Envoi, which is basically a portable, wireless sound system. Perfect for entertainment events and public speaking engagements, this compact, easily­ transportable system solves the dilemma of amplifying voices and music to a large audience when there is no access to AC power.

The Envoi is fully wireless, with up to 12 hours of battery life, a hand­held wireless microphone for mobility and even a Bluetooth receiver allowing users to stream music right from their smartphone or tablet. In addition, a fully­ featured, built­-in MP3 player can handle any playback files stored on SD card or USB thumb drive for total BYOD compatibility.

Envoi’s sound comes from 360­-watt amplifier built around Class D technology using 10” woofer and phase­-aligned tweeters.
