JK Audio says its Innkeeper 1x gets audio in and out of telephone lines, and says caller audio does not exhibit the transmit and receive crosstalk common to analog hybrids.
It connects audio signals to a standard analog telephone line, and uses a 16-bit DSP to monitor the phone line and audio signals continuously.
The dual-convergence algorithm achieves trans-hybrid loss typically exceeding 50 dB. The Innkeeper 1x’s front has a headphone jack and volume control. Users can monitor the send signal, the caller’s voice or a mix of the two. This output also is sent to rear-panel screw terminals so a monitor speaker can be added.
The company says remote features are on real screw terminals for ease of installation. Audio connections include mic/line switchable XLR input, XLR caller output and an additional, user-defined XLR output.
The Presence button enables a “richer” sound from the caller’s voice. This digital filter brings back some of the low-end lost in transmission.
JK Audio also touts the Innkeeper 1x’s ability to be remote controlled by the optional Guest Module 1, RIU-IP remote interface or the included RS-232 cable. The Guest Module 1 allows call drop and dialing functions to be controlled remotely while the RIU-IP allows control of functions through a Web browser.
