Broadcast Host 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 Broadcast Host controls and connectors are clearly
marked and ready for operation. The 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.
