General Wegener Receiver Characteristics

Salem Music Network uses the Wegener Unity 4000 digital receivers to decode the audio and control relays.  For details on the installation of this receiver, please read the Installation Manual.

One of the distinguishing characteristics of digital receivers is that they do not exhibit the "scratchiness" common to analog receivers when the signal degrades.  While able to provide a cleaner signal under more adverse conditions that would normally make analog unusable, the digital receivers will totally mute when the signal falls below the threshold.  This effect is known as the "cliff effect."

Another characteristic of a digital signal is the ability to encode the signal.  Only the Wegener Unity 4000 will be able to properly decode the audio and relay commands.
