JK Audio Innkeeper 1rx Digital Hybrid Phone Line Audio Interface for Console/IFB [Refurbished]
( 234541754938) )
Used/Tested - Fully Working • Excellent Cosmetic Condition • Usually $831 • Telephone Interface Unit with Auto Digital Line Nulling
Item is used, in excellent cosmetic condition and has been tested to confirm that it is working fully. As with almost all the JK products that I've tested, I found that the sweet spot for this device is with the input signal potted down low (ie. first level LED on only perhaps) and with the CALLER output gain set high. I suggest that you start testing at those points and see what sounds best to your ears and to a second tester on the other end of the line, rather than going just by the meters which will I believe lead you to over-drive the send signal.
The Innkeeper 1 gets audio in and out of telephone lines. Its excellent caller audio does not exhibit the transmit/receive crosstalk common to analog hybrids, making it perfect for radio or television talk shows, teleconferencing, or auto-answer IFB feeds.

A digital hybrid such as the innkeeper 1 connects audio signals to a standard analog telephone line without the variations in quality found with analog hybrids. The main function of a hybrid is to bring in the caller’s phone line, as clear and clean as possible. In the real world, when you send your voice down the telephone line it will bleed over into the caller’s audio, so the hybrid must adapt to the phone line in order to properly separate transmit and receive audio. We use a 16 bit DSP to monitor the phone line and audio signals continuously in order to deliver excellent separation. Our dual - convergence algorithm can achieve excellent trans - hybrid loss typically exceeding 50 dB, without any setup.
This wouldn’t be a JK Audio product without its fill of common-sense features. Check out the front-panel headphone jack and volume control. You can monitor either the send signal, the caller’s voice, or a mix of the two. This output is also sent to the rear panel screw terminals so you can easily add a monitor speaker. As a matter of fact, all of the remote features can be found on real screw terminals for ease of installation. And, of course, the audio connections: mic/line switchable XLR input, XLR caller output and an additional, user-defined XLR output. Now press the "Presence" button and you’ll get a richer sound from the caller’s voice. This digital filter brings back some of the low-end lost in transmission. And possibly the coolest feature: The Innkeeper 1 can be controlled by the Guest Module 1, the optional remote control keypad.
JK Audio Innkeeper 1 Features
From the front panel you can control on-hook/off-hook, and adjust headphone volume. Front-panel LEDs display signal levels and option status. The Send and Caller Volume controls are hidden behind an access panel to discourage unauthorized "tweaking". Auto-Answer and Presence switches are also hidden behind the access panel. The mic/line switch is located on the back of the unit, along with all audio and phone line connections.
