Emotiva Ultra UPA-1 Operation Manual page 16

In 'STANDBY' mode the front panel button will emit an amber glow, but the unit is not fully powered. A small amount of
amps are used in this mode, less than an average night light would use. If you are away for an extended period of time (more
than a few days), shut off all power to the amplifier with the main power switch on the back of the amplifier.
