JK Audio BluePack
Wireless Interview Tool for Bluetooth-Enabled Cell Phones


JK Audio's BluePack allows its user to conduct live man-on-the-street interviews through a cell phone equipped with Bluetooth.  This professional microphone preamp/headphone amplifier sports a 3.5 mm stereo line input jack that allows recordings to be mixed into the broadcast.

The BluePack's 3.5 mm stereo line output jack provides your full bandwidth microphone signal on the left channel and Bluetooth audio on the right channel.  Like any phone call, live interviews are limited to 3.4 kHz voice bandwidth.  The stereo output jack allows you to make a full bandwidth recording with your favorite audio recorder for transfer over the web or to your computer, editing bay, etc.

The stereo headphone output gives you a mix of the XLR microphone input, 3.5 mm input, and Bluetooth audio.  This powerful 1/2 watt stereo headphone amplifier will cut through any crowd noise.  JK Audio's BluePack also pairs to Bluetooth equipped sound cards and music players in full bandwidth stereo A2DP mode.
