Introduction

FCC Part 15 Compliance

JK Audio combines Bluetooth* Wireless Technology with profes­sional audio electronics in a convenient desktop design.
BlueKeeper pairs to your cell phone like a Bluetooth wireless
headset. Connect your favorite microphone and headphones for
dramatically improved sound quality at both ends of the call.
BlueKeeper also pairs to Bluetooth equipped sound cards and
music players in full bandwidth stereo A2DP mode.

What is an Audio Gateway?
BlueKeeper allows you to send mic and line level signals into your
wireless phone while maintaining excellent separation between
your voice and the caller. The stereo output jack provides your
voice on one channel and only the caller’s voice on the other chan­nel. The balanced XLR output jack contains only the caller’s voice.

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 channel. The headphone output gives you
a mix of the XLR input, 3.5 mm input, and Bluetooth audio.
