Wireless Headset Interface
JK Audio BlueSets

Communications Unleashed.

These headset interfaces plug directly into most Party- Line (PL) belt packs, replacing the wired headset. A 3.5 mm stereo headset jack contains a mic level output signal suitable for recording, with the beltpack headphone signal on the left channel, and the Bluetooth return signal on the right. A switch selects between connection to a 3rd party Bluetooth headset or a cell phone.

*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.
