Overview Introducing the innkeeper 1rx™ innkeeper 1rx will allow you to send and receive audio over analog telephone lines. While this may seem like a simple task that any telephone can do, the challenge is getting the best quality audio from such a miserable audio path. What is a Digital Hybrid? The innkeeper 1rx digital hybrid connects audio signals to a standard analog telephone line without the variations in quality found with analog hybrids.

Operation Send Signal Level The LEDs display the signal level as it goes out to the phone line. The goal is to drive the phone line at high enough levels to avoid phone line noise, but not so loud as to cause excessive clipping. Adjust the level control until you see occasional flashes of the second green LED (-9dB) and very rarely any flashes of the red -3dB peak Send LED. These flashes should occur only during loud speech bursts.
Configuration Auxiliary Telephone innkeeper 1rx does not disconnect the auxiliary telephone when you press the button. You can use an auxiliary phone to place or screen a call and then place it on hold. When you are ready to take the call on innkeeper 1rx, simply press the button. Your telephone will automatically release the hold. If you need to take the call back on the aux telephone, simply pick up the telephone handset before the innkeeper 1rx button is pressed.
Configuration Custom Dry Line Installation Innkeeper 1rx was designed to work on standard (wet) telephone lines as well as on custom PBX (dry) lines. Dry line installation is always a custom configuration and requires substantial telephone system knowledge. These installations are found in radio and television studios for both PBX and intercom applications.
Optional Remote Control Devices RIU-IP (Sold Separately) This remote control interface was designed for use with innkeeper 1rx as well as JK Audio innkeeper 2 and innkeeper 4 digital hybrids. This unit contains a web server which allows the user to send and receive control data through their web browser. RIU-IP can be connected to the user’s computer NIC card for direct control, to a switch or hub for network control, or to an Ethernet port with internet access for control from anywhere in the world.
Serial Port Interface ASCII Command Remote Control innkeeper 1rx digital hybrids built after April 2007 include an RS-232 interface for remote control applications. The enclosed CN081 serial port cable connects to the jack on the back of the innkeeper 1rx.
