JK Audio Interchange Intercom Phone Bridge

Interchange allows remote access to your party-line intercom through JK Audio Innkeeper Series Digital Hybrids. This professional half rack interface provides a four wire audio interface and remote control connection to JK Audio innkeeper LTD, innkeeper 1x/1rx, or innkeeper 2 Digital Hybrids. The front panel headset interface jack allows easy connection of your cell phone, tablet, or computer allowing remote access through a wireless phone or conferencing app.

Interchange contains a sophisticated intercom hybrid in a low noise pro audio design. The Listen-Always design allows both the phone hybrid / 4-wire connection and the cell phone headset interface to monitor the intercom just like any other belt pack. Listen mode is a high impedance bridging tap on the intercom line. Talk mode is enabled via a front panel switch, either Off, On, or Auto. Auto follows the phone hybrid Auto-Answer mode. Talk mode uses a solid state relay to properly couple Talk audio from the phone line and cell phone interfaces, to the intercom channel.

The Innkeeper 2 conference feature allows two callers to share one intercom connection. Alternatively, the included cables allow Line 1 and Line 2 of the Innkeeper 2 to be connected to two separate Interchange units, allowing connection to separate intercom loops.
