Standby Button

Places the Nº53 into Standby or Power Save mode, depending upon the state of the rear panel Power Save Mode switch. Pressing the Standby button while the amplifier is in Standby or Power Save mode turns on the amplifier.

Standby mode provides full AC power to the amplifier but mutes the outputs. Power Save mode powers only the low-voltage power supply, control circuits, and communication circuits so that only nonaudio functionality is available.

When the amplifier enters or exits Power Save mode, there’s an extended initialization period before the amplifier is fully powered on. During this period, additional Standby button presses are ignored.
