WARNING
Danger of hearing damage due to sudden high sound pressure levels!
Audio signals that are present at switch-on of the product or that can be present during
operation, can create sudden, very high sound pressure levels which can damage your
hearing.
X
Always lower the output level of the audio source before connecting it to the subwoofer
or starting it (pressing “play”).
This subwoofer can be used for commercial purposes. Commercial use is subject to the rules
and regulations of the trade association responsible. Neumann, as the manufacturer, is there-
fore obliged to expressly point out possible health risks arising from use. This subwoofer is
capable of producing sound pressure levels exceeding 85 dB(A) SPL. This is the sound pres-
sure corresponding to the maximum permissible level which is by law (in some countries)
allowed to aect your hearing for the duration of a working day (8 hours). It is used as a basis
according to the specifications of industrial medicine. Higher sound pressure levels and/or
longer durations can damage your hearing.
At higher sound pressure levels, the duration must be shortened in order to prevent hearing
damage. The following are signs that you have been subjected to excessive sound pressure
levels for too long a time.
• You can hear ringing or whistling sounds in your ears.
• You have the impression (even for a short time only) that you can no longer hear high fre-
quencies (temporary threshold shift).
WARNING
Interference due to magnetic fields!
This product generates stronger permanent magnetic fields that can interfere with cardiac
pacemakers and implanted defibrillators (ICDs).
X
Always maintain a distance of at least 4" (10 cm) between the subwoofer and the cardiac
pacemaker or implanted defibrillator.
Intended use of the product includes:
• having read this operating manual, especially the chapter “Important safety instructions”,
