Plain and simple may be the best words to describe the new
innkeeper LTD Digital Hybrid. Our simplest digital hybrid yet,
innkeeper LTD allows you to send line level signals into the
phone line while maintaining excellent separation between your
voice and the caller. The balanced XLR output jack contains only
the caller’s voice, making this the perfect companion to mixers,
consoles, and PA systems that demand talk show quality audio
from a phone line.
The digital hybrid connects audio signals to a standard analog
telephone line without the transmit / receive crosstalk common to
analog hybrids. Its Digital Signal Processor (DSP) continuously
monitors both the phone line and audio signals to deliver excellent
separation. This proprietary, dual-convergence echo canceller
algorithm can achieve excellent separation, typically exceeding
50 dB, without any setup and without sending a noise burst
down the line. While this may sound complicated, it’s all done
automatically during every call.
An auxiliary telephone is only required to place outgoing calls.
The auxiliary telephone is disconnected when you press the
“Call” button, and reconnected when you press the “Drop”
button. The “Remote” jack allows connection to a JK Audio Guest
Module, allowing remote control and dialing without an auxiliary
telephone.
Innkeeper LTD features Auto-Answer/Auto Disconnect for use
in IFB and monitoring applications. Other applications include:
telephone interviews, talk shows, church PA interface, and
conference room full duplex applications. This simple design
features recessed volume controls and no confusing DIP switches,
yet works reliably on standard analog phone lines around the
world.
The RA2 Rackmount accessory holds two innkeeper LTDs in a
1U rack space.
