Discussion
Which receiver control is left under the listener's command rather than automatic?
Answer: A
Volume sits after the detector and is deliberately manual, while the automatic gain control adjusts the radio and intermediate frequency stages to hold the detector's input steady. Handing the earlier gains to the listener would risk overloading the detector. Detector bias is fixed by design. The division between what the loop controls and what the user controls is a deliberate design decision rather than an accident of history.
