Startup
5.3.2.2 Standby mode
To switch the device to Standby mode, proceed as follows:
1. Select the «Power» button on the top right of the home screen.
↳
A dialog appears allowing you to either select the Back
button ( - Cancel), «Mute all» or «Standby».
2. Select «Standby».
↳
When the device is in Standby mode, both the «Power»
button on the right and the green Power on indicator on the
left are switched off. In addition, on the «Device view»
button, Standby flashes alternating with the Device name.
In Standby mode, the user interface of the device is still
operable.
The operating state (Standby mode) is stored when the
«Power» button is set to 'Off' and is restored when the
«Power» button is set back to 'On' again.
In Standby mode, the main power supply and the power
amplifiers are switched off to save energy. The display and
controls remain active to allow repowering of the device by
remote control or by selecting the «Power» button on the
Home screen.
3. To repower the device, select the «Power» button again.
Notes on Standby
When the device is set to Standby (or the mains power is
switched off), the movement of the loudspeaker cones in the
connected cabinets is no longer damped by the power amplifier
output. This removal of the damping makes them susceptible to
excitation by other loudspeakers in the surroundings. Audible
resonances may occur, and even absorption of low frequency
sound energy as the undamped loudspeakers act like a "bass
trap".
To permanently mute single subwoofer cabinets while others
are operated at the same time it is therefore preferable to use
the Mute function instead of Standby. However, the Standby
mode can be useful with mid/high systems as it removes any
residual noise from the system.
