JK Audio Innkeeper 2 Telephone Audio Interface

Innkeeper 2 squeezes two 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 2 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.

Menu SystemThe 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.

Call ConferencingCall Conferencing is activated by the front panel Conference button or the Remote Interface Unit. The Conference button joins both calls in a 2-way conference when both lines are off hook. Additional options in the configuration menu allow you to tailor the conference feature to your application. These options determine if audio signals on the Send and Caller XLR jacks are mixed or kept separate during a conference. Other applications include: telephone interviews, talk shows, church PA interface, and conference room full duplex applications.
