Wireless Phones and Notebooks

BluePack pairs to your cell phone like a Bluetooth wireless headset. This professional microphone preamp and powerful headphone amplifier make sure the message gets through. A 3.5 mm stereo line input jack allows recordings to be mixed into the broadcast.

The 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 back to the station. This stereo output jack allows you to make a full bandwidth recording using your favorite recorder for transfer back at the station or over the web.

Live Remotes

The stereo headphone output gives you a mix of the XLR microphone input, 3.5 mm input, and Bluetooth audio. This powerful ½ watt stereo headphone amplifier will cut through any crowd noise. BluePack also pairs to Bluetooth equipped sound cards and music players in full bandwidth stereo A2DP mode.

HD Voice

BluePack now features HD Voice technology, allowing 7 kHz Wide Band Speech when used with compatible phones on compatible networks. Read our HD Voice primer for more details.

*HD Voice: While standard phone calls have a narrow bandwidth of 300 Hz to 3.4 kHz, HD Voice calls offer 50 Hz to 7 kHz bandwidth. The additional 1.5 octaves on the low end gives voice a more natural sound, while the additional upper octave dramatically improves speech clarity and intelligibility.

*Wireless HD Calls: To take advantage of this extended bandwidth, both phones on the call must support HD Voice, and both phones must be on the same carrier, in coverage areas that support HD Voice.
