Safety instructions
Warning – High Voltage – Risk of Death!
Opening the Audiobeam while it is connected to the mains is likely to result in a life-
threatening 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:
yAudiobeam 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.
yAudiobeam 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.
yAstonishing 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 self-demodulation 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
왘When mounting Audiobeam, make sure that:
ythe ultrasonic sound wave can travel undisturbed for at least 1mbefore it
strikes the first surface.
ya 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!
ya minimum distance of 1 meter is maintained between Audiobeam and
combustible materials.
yAudiobeam is kept away from heat sources such as central heating radiators,
spot lights and lamps. Never expose Audiobeam to direct sunlight.
yAudiobeam 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).
왘Screw the mounting plate or the table or floor stand to the 5
/8" thread. Use the
thread adapter 쐂if necessary.
왘By 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
왘Screw Audiobeam onto a drive mechanism or a rotating mechanism using the
5
/8" thread. Use the thread adapter 쐂if necessary.
Putting Audiobeam into operation
왘Ensure that Audiobeam is not connected to the mains !
왘Use the sensitivity selector switch 쐇to adapt Audiobeam’s input sensitivity to
the audio source:
yAudio sources with a high output power (e.g. mixing console, CD or DVD
player):
upper position (+6 dBm).
yAudio sources with a low output power (e.g. portable mini disk player):
lower position (–14 dBm).

왘Use 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 쐋.
Audiobeam automatically emits ultrasound as soon as an audio signal (see
“Specifications”‘ on page 6) is present at the audio input INPUT 쐋.
왘Use the mains cable 쐆to connect Audiobeam to the mains. Secure the mains
cable with the steel clamp 쐎.
왘The LED operation indicator 쐃lights 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 쐃lights up red, one of the following problems may
have occured:
Audiobeam is defective
왘Please contact your Sennheiser distributor or the Sennheiser Service
department (for address, see last page).

Manufacturer declarations
Warranty regulations
The guarantee period for this Sennheiser product is 24 months from the date of
purchase. Excluded are accessory items and disposable batteries that are delivered
with the product; due to their characteristics these products have a shorter service
life that is principally dependent on the individual frequency of use.
The guarantee period starts from the date of original purchase. For this reason, we
recommend that the sales receipt be retained as proof of purchase. Without this
proof (which is checked by the responsible Sennheiser service partner) you will not
be reimbursed for any repairs that are carried out.
Depending on our choice, guarantee service comprises, free of charge, the removal
of material and manufacturing defects through repair or replacement of either
individual parts or the entire device. Inappropriate usage (e.g. operating faults,
mechanical damages, incorrect operating voltage), wear and tear, force majeure
and defects which were known at the time of purchase are excluded from
guarantee claims. The guarantee is void if the product is manipulated by non-
authorised persons or repair stations.
In the case of a claim under the terms of this guarantee, send the device, including
acces-sories and sales receipt, to the responsible service partner. To minimise the
risk of transport damage, we recommend that the original packaging is used. Your
legal rights against the seller, resulting from the contract of sale, are not affected
by this guarantee.
The guarantee can be claimed in all countries outside the U.S. provided that no
national law limits our terms of guarantee.
