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.
Digital hybrids allow you to send signals into the phone
line while maintaining excellent separation between your
voice and the caller. The balanced XLR output jacks contain
only the caller’s voice. Digital hybrids connect audio signals
to standard analog telephone lines without the transmit
/ receive crosstalk common to analog hybrids. 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.
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. Innkeeper 4 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.
