An echo canceller system includes a first echo canceller having a first voltage divider and an adaptable second voltage divider that is configured to generate a first replica of an echo. A second echo canceller is configured to generate a second replica of an echo and has tap values that are generated in response to an error signal. A controller is coupled to the first and second echo cancellers and includes a selection algorithm that responds to the tap values of the second echo canceller and selects a voltage divider value for the adaptable second voltage divider.
