Overview
BlueKeeper Wireless Audio Gateway
BlueKeeper pairs to your cell phone like a Bluetooth wireless headset. Simply connect your favorite microphone and headphones and enjoy an immediate improvement at both ends of the call. The professional microphone preamplifier provides a dramatic improvement in sound quality to the caller or back to the station if you are away from the studio. BlueKeeper also pairs to Bluetooth equipped sound cards and music players in full bandwidth stereo A2DP mode.
Recording Interviews
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 on the back of the unit provides your voice on one channel (in full fidelity) and the caller’s voice on the other channel. Connect this jack to your sound card or recorder. It’s perfect for radio or podcast interview recordings. The balanced XLR output jack contains only the caller’s voice. Connect to your mixing console or even to a PA system for everyone to hear.
Connections
The 3.5 mm stereo line input jack allows recordings to be sent into your 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. This same overall mix is also provided on a 3.5 mm mono mic level output jack.
