Audio over the phone lines!

The innkeeper 1x 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 1x perfect for radio or television talk shows, teleconferencing, or auto-answer IFB feeds. The innkeeper 1x is loaded with features that make it not only a smart solution for interfacing phones with broadcast, but to make the calls sound better as well. On-board filters and DSP allow every call to come in loud and clear, making innkeeper 1x indispensable for anywhere that phone calls need to be broadcast.

innkeeper1x at a Glance:

• Automatic Gain Control
  
• Digital Filtering
  
• Crystal Clear Sound

Automatic Gain Control
AGC (Automatic Gain Control) 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.

Digital Filtering
Press the “Presence” button and you’ll get a richer sound from the caller’s voice. This digital filter brings back some of the low-end lost in transmission. The Test Tone generator sends a 1 kHz full level tone either down the phone line or out the Caller XLR jack. This tone represents the maximum level transmit into the phone line or out the XLR jacks. The Test Tone generator is not required for tuning the digital hybrid. Auto-Answer simply answers on the first ring and disconnects at the end of the call.

Crystal Clear Sound
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. innkeeper 1x uses 16-bit DSP to monitor the phone line and audio signals continuously in order to deliver excellent separation. The 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.
