Controller for controlling an amplification gain of an amplifier for amplifying a high dynamic range signals for the analog / digital converter, wherein the having the above with a high dynamic that is configured to receive a representation of the range of the signal input interface, low signal amplitude than the high dynamic range signal a signal compressor configured to provide a low-amplitude representation of the high dynamic range signals. Comparator is the low-amplitude representation is configured to compare the signal amplitude with a predetermined threshold, the output interface, but provides a control signal to the amplifier, the control signal, wherein the signal amplitude of the low amplitude represent the predetermined threshold if it exceeds the said amplification gain is lowered so configured to control the amplification gain of the amplifier.
