The Interchange Intercom Phone Bridge from JK Audio is a professional half-rack interface designed to provide remote access to your party-line intercom through the JK Audio Innkeeper Series Digital Hybrids (sold separately). This unit provides a 4-wire audio interface and remote control connection to the JK Audio innkeeper LTD, innkeeper 1x/1rx, or innkeeper 2 Digital Hybrid (all sold separately). The front panel headset interface jack allows easy connection of your cell phone, tablet, or computer, thereby enabling remote access through a wireless phone or a conferencing app.
This intercom phone bridge contains a sophisticated intercom hybrid in a low noise pro audio design. The Listen-Always design enables both the phone hybrid / 4-wire connection and the cell phone headset interface to monitor the intercom. It features a Listen mode, which is a high-impedance bridging tap on the intercom line. This unit also includes a Talk mode that is enabled via a front panel switch, either Off, On, or Auto. Auto follows the phone hybrid Auto-Answer mode. The Talk mode uses a solid-state relay to properly couple Talk audio from the phone line and cell phone interfaces, to the intercom channel.
