Troubleshooting and Techni-
cal Information
Problem
Cause
Solution
The subwoofer switches itself off
although music is being played.
There is hardly any low-frequency signal available. This
can happen if the music or movie itself does not contain
very low frequencies (e.g. long dialogues).
X
The subwoofer will switch on automatically as
soon as low frequent signals are detected.
X
Use the temporary manual On facility by briefly
pressing the green
I
button on the remote
control.
The subwoofer responds intermittently
to remote control commands.
•
The remote control battery is becoming weak.
•
The remote control eye (either front- or back panel) is
obstructed.
•
The subwoofer is in direct, strong sunlight.
X
Replace battery.
X
Ensure there is a clear line-of-sight from the
remote control to either the front- or back panel
remote receiver. If this is not possible, consider
an IR repeating system which consists of a
separate remote receiver which connects by wire
to a remote control emitter which can be
positioned close to the subwoofer's remote eye.
Consult your Dynaudio dealer for help.
X
Avoid placing the subwoofer in strong direct
sunlight.
The subwoofer will not switch on at all.
•
AC mains cable has become disconnected
(no LEDs are lit)
•
Mains switch on the rear is switched to Off
(no LED are lit)
Make sure to switch the system off first before
making any changes!
X
Reconnect mains cable.
X
Switch mains back on.
