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.
