Overview
Innkeeper 1rx Digital Hybrid
The innkeeper 1rx gets audio in and out of analog telephone lines. Its excellent caller audio output does not exhibit the transmit/receive crosstalk common to analog hybrids. This makes innkeeper 1rx perfect for radio or television talk shows, teleconferencing, or auto-answer IFB feeds. The main function of any hybrid is to bring in the caller’s voice from the phone line, as clear and clean as possible. In the real world, when you send your voice down the telephone line it has a tendency to bleed over into the caller’s audio. The hybrid must adapt to the phone line in order to properly separate transmit and receive audio. We use a 16-bit DSP to monitor the phone line and audio signals continuously in order to deliver excellent separation. Our dual-convergence echo canceller algorithm can achieve excellent transhybrid loss, typically exceeding 50 dB, without any setup and without sending a burst of noise into the phone line.
Automatic Gain Control (AGC)
Adjusts the caller volume to an average level. AGC will tame a loud caller, and boost a quiet caller or quiet long distance connection.
Caller Ducking
Drops the Caller output level by 9 dB whenever the host speaks. This keeps the host “in charge” of the show, automatically making sure the caller never overpowers the host by attempting to talk over the host’s voice.
Presence
Press the “Presence” button to get a richer sound from the caller’s voice. This digital filter brings back some of the low-end lost in transmission.
Talk Show
For Talk Show applications combine innkeeper 1x/1rx with the Concierge 2x6 Switch Core and a Guest Module Control Surface.
