BlueSet Wireless Headset Interface


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.


Headset Connect
Pair BlueSet to your Bluetooth headset. Leave your belt pack on the desk as you walk around the room.

Phone Connect
Pair BlueSet to your cell phone to extend your system around the world. The belt pack Mic/Talk button controls audio from the cell phone into the intercom system.
