A phono input stage (209) has an adjustable input impedance. A pre-amplifier (207) with variable gain amplifies an output from the phono stage. A power amplifier (201) amplifies an output from the pre-amplifier. The temperature of the power amplifier is monitored and an output (202) from the power amplifier is supplied to an output transducer. A touch sensitive screen (104) receives input gestures to provide control signals to a control processor (203). The control processor operates first relays to control the input impedance, operates second relays to control the adjustable gain and also operates the second relays in order to attenuate output volume in response to identifying the monitored temperature as being above a predetermined threshold."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Processing analog audio signals","description":"An analog audio signal derived from a vinyl recording is processed via an input transducer, such as a moving magnet or moving coil device.
