JK Audio Innkeeper 4, Multi-Line Digital Hybrid



When a Single Line Hybrid Isn't Enough.




When a Single Line Hybrid Isn't Enough.

Innkeeper 4 squeezes four independent digital hybrids in a 1U rack space. The front panel keypad, display, and handset jacks provide easy speed dialing and call setup. Its excellent caller audio output does not exhibit the transmit/receive crosstalk common to analog hybrids. This makes innkeeper 4 perfect for radio or television talk shows, teleconferencing, or auto-answer IFB feeds. The 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.

  • Excellent Separation of Caller and Talent Voice
  • Four Line Hybrid

Menu System

The menu driven keypad and back lit display allow you to store 50 phone numbers by name in a phone list. You can also use the display to set features such as the number of rings before auto answer, master send channel selection, and test tone output. An auxiliary telephone jack is provided for each line. The auxiliary telephone is disconnected when you press the Call button, and reconnected when you press the Drop button.

Talk Show

For Talk Show applications combine innkeeper 2 with the Concierge 2x6 Switch Core and a Guest Module Control Surface.
