The BlueDriver-M3 Bluetooth Wireless Audio Interface (3-Pin XLR-M) from JK Audio is a compact adapter that allows you to send audio from a Bluetooth cellphone or headset to your professional audio equipment. The standard 3-pin XLR male connector plugs into the mic-level input of a mixer. You can then pair the device via Bluetooth to a headset or cellphone. A switch on the side of the BlueDriver-M3 makes it easy to switch between headset and cellphone modes.
The unit also has a 3.5mm stereo input jack that will accept a signal from the headphone output of the mixer for transmission back to the cell phone or headset. An LED light shows when a wireless connection is made. The interface has an internal Li-ion battery that operates for approximately 10 hours on a single charge. It can be recharged via the mini USB connection.
