Abstract
In a programmed audio amplifier system, the volume setting when the system is turned on is conditionally related to the last volume setting, i.e., immediately before the amplifier was turned off. At turn-on the system remains at the last volume setting as long as it is less than a preset volume setting. However, at turn-on the system exhibits the preset volume setting if the last volume setting exceeds the preset volume setting.
