SYSTEM DESCRIPTION.
A large ring button enables you to pick up the line from the unit itself or from your mixer when connected
via its GPIO to the telephone Hybrid. When a call comes in it lights up green in the rhythm of the ring. When
the line is picked up by pushing the button it turns into red. When it starts blinking red the line connection is
lost.
Both levels of receive and send can be adjusted to suit your requirements. Incoming signals can be
tailored by the variable high and low cut signal while talking to people calling the station.
A ducking system reduces the incoming signal while talking to people calling the station to provide for an
improved intelligibility.
