Audio Physic REFERENCE On-Wall Owner's Manual page 12

General Tips
Please follow the instructions in the chapter „Unpacking and Assembly" to ensure the safe and correct installation
of your loudspeakers.
The loudspeakers should reach a temperature that is approximately equivalent to room temperature before you
connect them to the HiFi system and operate them. This instruction predominately refers to the winter months in
case the loudspeakers were previously stored in a cold environment.
The drivers in this range of AUDIO PHYSIC loudspeakers use a unique mounting technique. Rather than being
directly mounted onto the cabinet of the loudspeaker, the drill holes of the loudspeakers contain special
neoprene plugs. These neoprene plugs tighten in the mounting hole when the screws are fitted, creating a
permanently elastic connection between the driver and the cabinet that reduces resonance. You do not need to
tighten these screws. Re-tightening the screws may damage the plugs and have a negative effect on the sound.
Maintenance
The high-quality cabinets of the REFERENCE On-Wall loudspeakers in large part have a glass surface. As a rule, a
fine, soft and damp cloth is all that you need to clean the surfaces. If a cleaning agent is required, use this to
dampen the cloth and do not directly apply it to the surface. It is best if you test the suitability of the cleaning
agent on a less visible part of the cabinet.
The drivers do not normally need to be cleaned. Dust particles fall off quickly when the loudspeakers are
operated. You can, however, use a soft brush to lightly brush over the surfaces of the drivers . When doing so,
make sure you do not put any pressure on it.
Please never use any cleaning agents on the drivers. Do not expose the loudspeakers to direct sunlight. Anodised
surfaces are sensitive to acids and alkalis and to ultraviolet light and may fade.
Burning In
The loudspeakers first reach their full sound potential after a specific burn-in period. We burn in the drivers at our
factory prior to assembly, meaning that they normally only need a burn-in period of a few hours at a normal room
volume and with music that has a range of frequencies that is as wide as possible, for example orchestral pieces.
Recordings containing ‚white or pink noise' such as those available on many so-called Test CDs are also ideal -
however, for safety reasons, these pieces should never be played at high volumes.
Stray Magnetic Fields
The magnetic field created by the individual driver magnets may to some extent have an effect outside of the
loudspeaker. This stray magnetic field may interfere with other devices, particularly televisions and monitors with
cathode ray tubes, but do not interfere with modern LCD or plasma televisions, In the case of CRT television sets,
for example, this may cause changes in colour in the picture. We recommend that you place your loudspeakers
approximately half a metre away from such devices (and also from magnet tapes, video cassettes, credit cards
with magnetic stripes, etc.).
Transportation
Where possible, please retain the loudspeaker packaging. You can then securely transport your loudspeakers if
you move house. If you have REFERENCE LINE loudspeakers in our „Glass High Gloss" design, please pack them
securely and transport them carefully in order to avoid damages.
