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.

This small desktop unit easily converts to a rack-mount unit using the optional RA2 Rack Panel. The RA2 holds 2 innkeeper LTDs in a 1U rack space.
