Phantom Powered In-line Bluetooth Audio Receiver The Switchcraft 318BTS is a reliable and rugged 2-channel Bluetooth dongle that is designed to make any Bluetooth device compatible with a mixer. The 318BTS has enhanced range and low latency, which make it a perfect option for connecting tablets, smartphones, or computers to your audio system. If you're playing a gig at a venue that has its own sound system, you can plug this receiver straight into the board and control your music from afar with no signal loss. And at GearNuts, we love that this receiver can be powered by a micro USB phone charger if phantom power is unavailable. If you're a musician on the go, the Switchcraft AudioStix 318BTS could be your new best friend.Switchcraft AudioStix 318BTS XLR Bluetooth Receiver Features: Stereo or mono output selector Phantom powered Bluetooth version 4.0 Paired devices memory: 8 Built to last
