4.4.3. Standby mode
To switch the device to Standby mode ... :
1. Tap 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.
Note: In Standby mode, the user interface of the device is still
operable.
3. To repower the unit, tap the «Power» button.
Startup time from Standby state is < 1 sec.
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 and the loudspeaker outputs are
electronically isolated. The display and controls remain active to
allow repowering of the device by remote control or by tapping
the «Power» button on the Home screen.
Note: 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.
