Safety instructions
Warning – High Voltage – Risk of Death!
Opening the Audiobeam while it is connected to the mains is likely to result in a lifethreatening electric shock!
There are no user serviceable parts inside – if the Audiobeam should become defective, any
repairs must be carried out by an official 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.
Is there a danger of hearing damage?
A new study tested the Audiobeam for possible damage to hearing due to the ultrasound it
emits and certified its harmlessness. In this study, Prof. Dr.-Ing. Joachim Herbertz, the
President of the first International Ultrasonics Congress, came to the following conclusion:
“The ultrasound emitted by the Sennheiser Audiobeam is safe at a minimum distance of 20
cm from the protective grid”.
The limit values of the European and international standards and guidelines IEC 71672-1, IEC
61012, GEFAU N 01 and 2003/10/EG are complied with.
How Audiobeam works
Audiobeam is an acoustic spotlight. This means:
y 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.
y Audiobeam limits sound reproduction to precisely defined areas – adjacent areas are kept
sound-free. This helps to create a calmer overall atmosphere in rooms. Several Audiobeams
can be installed in one room without affecting each other.
y Astonishing audio effects amaze visitors as Audiobeam allows the sound to come from
unusual directions.
Audiobeam uses state-of-the-art ultrasonic sound transmission technology:
Audiobeam works with ultrasound, modulating the audible sound onto an ultrasonic carrier
frequency. Due to the nonlinearity of air, the desired audio signal is produced by the selfdemodulation effect of the ultrasound wave. At an angle of 30°, a slim sound beam is created
that can be heard over long distances.

Mounting Audiobeam
Correct mounting conditions
왘 When mounting Audiobeam, make sure that:
y the ultrasonic sound wave can travel undisturbed for at least 1 m before it strikes the
first surface.
y a minimum distance of 10 cm is maintained between Audiobeam and adjacent objects
so that any heat generated can dissipate. Make sure that the air vents at the top and
rear of the unit are not covered or blocked!
y a minimum distance of 1 meter is maintained between Audiobeam and combustible
materials.
y Audiobeam is kept away from heat sources such as central heating radiators, spot lights
and lamps. Never expose Audiobeam to direct sunlight.
y Audiobeam never gets wet.
Mounting Audiobeam in a fixed position
To ensure that Audiobeam is always orientated towards the correct area of interest, you
should mount Audiobeam in a fixed position. Use a mounting plate for wall or ceiling
mounting. For mobile installations, use a table or floor stand (see “Accessories”‘ on page 5).
왘 Screw the mounting plate or the table or floor stand to the 5/8" thread. Use the thread
adapter if necessary.
왘 By using a gooseneck or swivel joint (see “Accessories”‘ on page 5), directly orientate
Audiobeam towards the correct area of interest or the reflection area.
Mounting Audiobeam movably or rotatably
왘 Screw Audiobeam onto a drive mechanism or a rotating mechanism using the 5/8" thread.
Use the thread adapter if necessary.
Distance sensor
For reasons of test engineering, a distance sensor with a switch is located on the bottom
right of the emitter surface.
If the distance sensor is “on”, the Audiobeam turns off whenever persons or objects are
situated at a distance of less than four meters in the emitting direction of the Audiobeam.
For this reason, the distance sensor is factory-preset to “off” and should as a rule stay like this
during operation in order to prevent automatic turn-off (for further information, please refer
to the service instructions).
Putting Audiobeam into operation
왘 Ensure that Audiobeam is not connected to the mains !
왘 Use the sensitivity selector switch to adapt Audiobeam’s input sensitivity to the audio
source:
4
y Audio sources with a high output power (e.g. mixing console, CD or DVD player):
upper position (+6 dBm).
y Audio sources with a low output power (e.g. portable mini disk player):
lower position (–14 dBm).
왘 Use an XLR-3 cable to connect the audio source (e.g. CD or DVD player, mixing console,
receiver of a wireless microphone) to the audio input INPUT .
Audiobeam automatically emits ultrasound as soon as an audio signal (see
“Specifications”‘ on page 6) is present at the audio input INPUT .
왘 Use the mains cable to connect Audiobeam to the mains. Secure the mains cable with
the steel clamp .
왘 The LED operation indicator lights up green, indicating that Audiobeam is ready for
operation (standby).
Note: If you do not use the unit for a period, disconnet the mains connector from the wall
socket. This helps to increase the service life of Audiobeam and save energy.
Troubleshooting
If the LED operation indicator lights up red, one of the following problems may have
occured:
On/off switch for distance sensor is activated
왘 Someone has entered the security area of four meters in front of or around the Audiobeam
and the motion sensor has triggered. After the person has left this area, Audiobeam
automatically turns on again after 30 seconds.
왘 Solution: Set the on/off switch for the distance sensor to “off”.
Audiobeam is defective
왘 Please contact your Sennheiser distributor or the Sennheiser Service department (for
address, see last page).
