Care and cleaning tips
Caution!
Improper handling of the speaker may result in damage.
• Always unplug the speaker before cleaning it!
• Before recommissioning, make sure that all connections are correct, that
there are no short circuits and that the speaker is completely dry.
• Never use strong cleaning agents or solvents such as petrol, spirit or similar!
Enclosure
We recommend commercial window cleaner sprayed onto a cotton cloth. This
allows almost all fingerprints and dust to be easily removed. Alternatively, you
can also use window active foam.
We advise against the use of microfibre cloths! These can cause mini scratches
in the surface.
Diaphragms and Speaker Chassis
To remove dust from a loudspeaker chassis, a lint-free cotton cloth is sufficient
to wipe the membrane lightly with very little pressure.
Unpacking and Scope of Delivery
Unpacking
When unpacking your speaker, do not use sharp or pointed objects to avoid pos-
sible damage to the enclosure. Please keep the packaging in a safe place in case
you need to transport the speaker at a later date.
Scope of delivery
If the delivery is complete, it contains the following parts:
1 nuBoxx AS-425 max active loudspeaker
1 Cloth grille
1 Remote control with battery
1 Mains cable, 3 m
1 Fibre optic cable with TOS-Link plugs, 1.5 m
1 Stereo 3.5mm jack to cinch cable, 1.5 m
1 High Speed HDMI Cable with Ethernet, 1.5 m
Auto power off
The nuBoxx AS-425 max Soundbase can switch to the stand-by mode (< 0.5 Watt)
via an automatic power off function. The behaviour depends on the chosen input.
If either Bluetooth or AUX is selected, the loudspeaker switches to standby mode
after a maximum of 20 minutes without audio input. With the digital inputs COAX
or OPTICAL, the auto-off circuit also reacts directly to the absence of a digital
data stream and thus allows for a faster switch-off. The playback device must
deactivate the data stream accordingly. When switched to the HDMI eARC input,
the auto off circuit reacts directly to the appropriate CEC command, transmitted
from the TV system.
Note: The auto power off feature can be enabled or disabled by pressing and hold-
ing the remote control’s wide button for 7 seconds within 15 seconds of power on.
The LED ring flashes once to confirm that the standby automatic is deactivated. The
LED ring flashes three times to confirm that the function has been (re-)activated.
Auto power on
The electronics of the AS-425 soundbase have an automatic switch-on function,
that automatically wakes them from stand-by mode as soon as a sound signal or
data stream is present. The signal must be applied to the input that was selected
during the automatic switch-off process.
• However, this function is not available for Bluetooth devices.
• At the other inputs, Auto power on is only active if the AS-425 is set to standby
mode by the Auto power off function. If standby mode has been set manually by
pressing the button on/off on the remote control or by a three second-long press of
the dial on the front of the speaker, the automatic switch-on function is deactivated.
