JK Audio BDRVF3 BlueDriver-F3 Bluetooth Audio Interface, XLR Female Input

Plug a dynamic mic or a mixer output into the JK Audio BlueDriver-F3 and its 3-pin female XLR input routes the audio to a paired Bluetooth phone, headset, or speaker. A 3.5 mm stereo headphone output lets you monitor the return from the Bluetooth device on wired ear buds or headphones.

In Phone mode, it pairs to a cell phone for wireless audio-for-video with a compatible camera app (about 25 ms latency using the HD Voice profile), live man-on-the-street interviews dialed into the station, or a backup audio path when the IP codec's internet connection drops. HD Voice supports 7 kHz wide-band speech on compatible phones and networks.

Headset mode connects to Bluetooth headphones or wireless speakers with full 20 kHz A2DP audio, sending the mono XLR signal to both channels; A2DP adds about 150 ms of delay, so it suits pre-recorded or broadcast feeds rather than live mics. An internal Li-ion battery runs more than 6 hours and charges via Mini-USB.
