 Innkeeper 1: Signal-to-Telephone Link Without Variations

2.09.2007 	

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.
