Arrangement and method for controlling an amplifier circuit corresponding to energy uptake in the amplifier circuit

An amplifier comprising:

• at least one input terminal for receiving an input signal to be amplified;
• a first output terminal and a second output terminal, the first output terminal and second output terminal operable to output an output signal corresponding to the amplified input signal;
• and
• a circuit connected between the first output terminal and the second output terminal, the circuit operable to electrically disconnect the first output terminal from the second output terminal when the amplifier is in a first operating state wherein the amplifier substantially takes up no electrical energy via the first output terminal and the second output terminal, the circuit further operable to electrically connect the first output terminal to the second output terminal when the amplifier is in a second operating state wherein the amplifier is taking up electrical energy via the first output terminal and the second output terminal, the circuit thereby draining the electrical energy taken up away from the first output terminal via the second output terminal when the amplifier is in the second operating state.
