美国JK AUDIO   Interchange

美国JK AUDIO Interchange

The Missing Link.

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 for JK Audio innkeeper LTD, innkeeper 1x/1rx, or innkeeper 2 Digital Hybrids for POTS lines, or JK Audio AutoHybrid IP2 for VoIP lines. The front panel headset interface jack allows easy connection of your mobile phone, tablet, or computer allowing remote access through a wireless phone or conferencing app.

Listen-Always Design

The Listen-Always design allows both the phone hybrid / 4-wire connection and the mobile 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.

Conference

The Innkeeper 2 or AutoHybrid IP2 conference feature allows two callers to share one intercom connection. Alternatively, the included cables allow Line 1 and Line 2 of the Innkeeper 2 or AutoHybrid IP2 to be connected to two separate Interchange™ units, allowing connection to separate intercom loops.
