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.
Note
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.
