JK Audio's 4-Pin/5-Pin Male XLR Outerloop Wireless Intercom Belt Pack functions as a wireless link to your intercom system. This universal belt pack provides connections for your existing 4-pin or 5-pin intercom headset, routing audio through your mobile device over a Bluetooth wireless connection. Use your cell phone to call into your intercom phone bridge or station phone coupler for a global wireless link.
Adapting to the mixed-up intercom world, this model features both 4-pin and 5-pin XLR headset jacks. Easy-to-use send and receive level controls, a push-on, push-off Talk button, as well as a recessed sidetone level control. All the comforts of a standard belt pack whether you are around the corner or around the world.
Outerloop also features a switch that selects between pairing to a phone or to a headset. In Phone mode, Outerloop pairs to your cell phone, notepad, or computer just like any other Bluetooth headset. In Headset mode, you can pair to another Outerloop or to a standard Bluetooth headset, providing a short range secure wireless point-to-point intercom. Outerloop to Outerloop connections default to HD Voice (50 Hz to 7 kHz) bandwidth. Many new Bluetooth wireless cell phones and headsets also provide HD Voice bandwidth.
