How AudioBeam works
AudioBeam is an acoustic spotlight. This means:
! AudioBeam is able to focus sound – either directly or via reflections on a
surface. This allows e.g. information in museums and at exhibitions to be
radiated directly from the exhibits – only visitors standing directly in
front of an exhibit are addressed.
! AudioBeam limits sound reproduction to precisely defined areas –
adjacent areas are kept sound-free.
This allows e.g.
the soundtrack from
a video to be projected in different languages, without the need for
headphones. The visitors simply have to enter the desired “language
area”.
AudioBeam uses state-of-the-art ultrasonic sound transmission technology:
The desired audible sound is created at a distance of four to up to ten
meters directly in front of AudioBeam and at an angle of approx. 30°. As
soon as someone comes closer than four meters to AudioBeam, a built-in
distance sensor automatically turns off the unit.
Safety instructions
Possible danger for persons with cardiac pacemakers!
Possible danger of hearing defects!
At a distance of less than four meters in front of AudioBeam, ultrasonic
frequencies may disturb the function of cardiac pacemakers and may
cause damage to the hearing!
Make sure that no-one can come closer than four meters to AudioBeam –
especially when mounting the unit movably or rotatably.
Warning of life-threatening electrical shock!
If AudioBeam is connected to the mains, opening AudioBeam may result in
a life-threatening electric shock!
If AudioBeam should be defective, repair must be carried out by your
Sennheiser service partner. If the unit is opened in breach of this
instruction, the warranty becomes null and void.
Risk of fire!
AudioBeam generates heat! Make sure that the air vents of the unit are not
covered or blocked!
Keep AudioBeam away from heat sources and never expose AudioBeam to
direct sunlight! Maintain a minimum distance of 1 meter between
AudioBeam and combustible materials.
Attention!
If liquids or small parts which conduct electricity find their way into the
interior or to the connecting sockets of AudioBeam, this can cause a short
circuit!
Use AudioBeam in dry rooms only and keep liquids and small parts which
conduct electricity away from the unit and its connecting sockets. For
cleaning AudioBeam, only use a dry or slightly damp cloth. Never use any
solvents or cleansing agents.
