d&b audiotechnik D40 - Energy Saving Modes (EcoMode)

Device setup
6.5.5 Energy saving
EcoMode
EcoMode enables the amplifier to automatically switch between
normal and low power consumption modes depending on the
current output level requirements. When enabled and the output
level of all channels is continuously low, a 60 second countdown
will be started, indicated by the message
«Counting down to EcoMode» in the bottom left corner.
When the output signals has been low for the full 60 seconds,
EcoMode will be activated and power consumption is reduced.
This is indicated by the green LED on the «Eco» button, the text
«EcoMode» in the bottom left corner and the text «Eco» on the
power button.
In EcoMode, the amplifier still outputs the audio input signals.
Once the output level of any channel exceeds the amplifier's
capabilities in EcoMode, the amplifier automatically switches back
to normal operation without interruption of the audio output
signals.
Note: Switching from low to normal mode may be
accompanied by audible compression during the first 300 ms.
