General Safety Instructions
Loudspeakers produce a static magnetic field even if they are not connected or are not in use. Therefore make
sure when erecting and transporting loudspeakers that they are nowhere near equipment and objects which
may be impaired or damaged by an external magnetic field. Persons with cardiac pacemakers must maintain a
safe distance.
The minimum recommended safety clearance is 1 m.
Never stand in the immediate vicinity of loudspeakers driven at a high level. Professional loudspeaker systems
are capable of causing a sound pressure level detrimental to human health. Seemingly non-critical sound levels
(from approx. 90 dB SPL) can cause hearing damage if people are exposed to it over a long period.
All connected cables must be laid in such a way that they cannot be crushed by objects and that nobody can
step on them! Replace damaged cables immediately and do not use them!
Use only accessory parts specified by Voice-Acoustic or original accessory parts from Voice-Acoustic. Check all
cabinets and accessories regularly for wear and replace them if necessary.
Do not set up the loudspeakers in places where they are permanently exposed to moisture, dust, dirt or direct
sunlight.
Care
Wipe the surface of loudspeakers only with a damp cloth and pure water. In case of heavy pollution, repeat the
above procedure several times if necessary. Do not use any chemical additives or aggressive detergents, as
these may harm and damage the surfaces.
Transport and storage
When transporting and storing the unit, it is important to ensure that the surface and front grill of the loudspe-
aker are not damaged. Moisture can penetrate through exposed wood surfaces and cause the wood to swell.
A bent or broken front grill will no longer adequately protect the sensitive speaker membranes. In addition,
appreciable dust deposits may considerably impair the functionality of a loudspeaker membrane. For this rea-
son, the loudspeakers should be transported and stored in a safe, careful, dry and largely dust-free manner.
The following accessory parts for transport and storage are available from Voice-Acoustic:
■
Carrying bag for up to 4 x Alea-4 with u-bracket (Art.-Nr. 500042000)
■
Heavy duty flightcase for up to 4 x Alea-4 (Art.-Nr. 505003000)
Note: The original packaging is unsuitable as permanent storage and transport packaging!
