JK Audio‘s new BlueKeeper is a Bluetooth device that allows you to send mic- and line-level signals into your wireless phone while maintaining separation between voice and the caller.
The stereo output jack on the back provides your voice on one channel and only the caller’s voice on the other. The balanced XLR output jack contains only the caller’s voice.
BlueKeeper pairs to a cell phone like a Bluetooth wireless headset. The professional microphone preamplifier provides a dramatic improvement in sound quality, according to the manufacturer. BlueKeeper also pairs to Bluetooth-equipped sound cards and music players in full bandwidth stereo A2DP mode.
The 3.5 mm stereo line input jack allows recordings to be sent into the Bluetooth device. The 3.5 mm stereo line output jack provides your full bandwidth send mix on the left channel and Bluetooth caller audio on the right. The headphone output gives you a mix of the XLR input, 3.5 mm input, and Bluetooth audio.
