Introducing the Broadcast Host™
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.
What is a Digital Hybrid?
The Broadcast Host 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 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. W
e use a 16 bit DSP (Digital Signal Processor) to continuously
monitor the phone line and local audio signals to deliver excellent trans-hybrid
loss, also known as separation. Our dual-convergence algorithm can achieve
excellent separation, typically exceeding 50 dB.
Ready to go?
The Broadcast Host controls and connectors are clearly marked and ready for
operation. If this is your rst exposure to a hybrid, we suggest that you read the
entire manual to allow you to take advantage of all these features.
