JK Audio innkeeper 4 - Manual (Page 2)

Innkeeper multi line digital hybrids will allow you to send and
receive audio over analog telephone lines. While this may
seem like a simple task that any telephone can do, the
challenge is getting the best quality audio from such a limited
audio path.
A digital hybrid connects audio signals to a standard analog
telephone line without the variations in quality found with
analog hybrids. The main function of a hybrid is to bring in
the callers 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 continuously monitor the phone line and
audio signals to deliver excellent separation. Our dual-
convergence algorithm can achieve excellent trans-hybrid
loss, typically exceeding 50 dB, without any setup.
The Innkeeper 2/4 feature diagram will help you pinpoint any
minor questions that you may have. If this is your first
exposure to a hybrid, we suggest that you read the entire
manual to allow you to take advantage of all these features.
Before you pick up the phone... Please thumb through the
rest of this manual. You might find those deep technical
questions are covered on later pages.
