PRODUCT INFORMATION
HS 800 Digital / HS 800 Digital Rotor / HS 800 Digital 6pin
Thank you for selecting the HS 800 Digital aviation headset. Please take some time to read
carefully through this product information before using the headset.
1. Safety Information
When using the HS 800 Digital headset, typical aircraft sounds (e.g. those from engines,
propellers, warning alarms etc.) may sound different to you. Before operating the aircraft, please
make sure that you can hear and recognise these sounds. Set the volume to safe levels that do
not interfere with your ability to hear important sounds and warning alarms.
2. Applications
The HS 800 Digital is an aviation headset which has a closed design to meet high standards.
3. DANR Function
Noise affects the ability to concentrate and the consciousness of situations: properties which
are important for your safety when flying! Permanent noise can even damage your hearing.
3.1 Active Noise Reduction
The function of the active noise reduction is based on the principle of the phase inverse sound.
In standard analogue ANR headsets, small microphones in the ear cups receive the noise and an
analogue filter circuit (NC filter) produces an audio signal with inverse wave shape - phase
inverse. The original noise is superimposed by the phase inverse audio signal and reduced: The
ear drum receives less noise.
The active noise reduction is especially effective in the deep frequency range (25 to 500 Hz).
With higher frequencies it is less effective. This is the reason why a headset often provides a
combination of active and passive hearing protection.
3.2 Digital Adaptive Noise Reduction DANR
Active noise reduction on an analogue basis for Aviation headsets has been existed for more than
20 years. A headset with analogue active noise reduction starts working after switching it on.
The properties of the analogue filter always remain the same independent on the acoustic
surrounding. Therefore, an analogue active headset cannot adapt to modified acoustic situations.
This applies the advantages of the digital signal processing. The NC filter has been programmed
as a software algorithm and processes digitalised audio signals on a micro processor. In addition
to a more precise result the main advantage is, that it intelligently reacts to various acoustic
surroundings. This includes an automatic activation when the engine is started and an adaption
to peaks, which are typical for engine noise. An analogue NC filter cannot differ between very
loud and quiet frequencies.
Note:
As DANR is activated automatically when the engine is started you will not notice any
noise reduction and background noise when the DANR function is activated with
normal ambient noise. You can check the DANR function when you deactivate the
DANR function during the flight.

4. Usage
4.1 How to store and maintain the HS 800 Digital
It is best to store the headset in the supplied padded leather bag. While storing the headset
make sure that it is not exposed to extreme temperatures, humidity or direct sunlight. Use
a soft cloth when cleaning the HS 800 Digital. For the leather pads, you should use an
appropriate leather care cleaner. Do not immerse the headset in water.
4.2 How to prepare the Headset for Use
4.2.1 Adjusting the Headband
For best comfort and noise attenuation, the headband has to be adjusted to fit your head
properly.
Wear the headset so that the headband runs over the top of your head and adjust the headband
so that
• your ears are completely enclosed by the ear cushions,
• you feel a gentle pressure around your ears,
• both ends of the headband have the same length to ensure a proper fit
4.2.2 Adjusting the Microphone
• Place the wind shield onto the microphone and make sure that the microphone is completely
enclosed.
• Bend the flexible gooseneck so that the microphone is placed about 2 cm in front of the
middle of your mouth. In order to avoid overstretching and premature wear and tear never
bend the gooseneck more than 90°.
• Turn the microphone holder (not the gooseneck!)
to position the microphone on the left or right
hand side of the mouth.
• Adjust the gain of the microphone via a
potentiometer by using the supplied small
screwdriver (refer to the illustration).
• At the factory a high gain has been set. The
gain is reduced by turning the potentiometer
to the left.

4.3 How to use the Audio Box
4.3.1 Controls and Indicators
On/Off button for external audio interface
Operating control LED for external audio interface
Volume controls for headphone
Auto-Mute button
Status LED for the Auto-Mute function
Operating control LED for the DANR function
Mono/Stereo switch
Battery compartment for two AA batteries
Connection for mobile phones or music players
Connection for external power supply
4.3.2 Volume Control
Set the volume controls to a medium level. With the left control you can adjust the volume
for the left ear and vice versa, if you put on the headset to wear the microphone on the left hand
side. With the volume controls only the volume of the intercom signal can be adjusted. The
volume of external audio sources (e.g. MP3 players) must be set at the appropriate devices.
If the volume level is set too high you can damage your hearing and critical sounds
such as warning alarms are hard to hear!
4.3.3 Mono/Stereo Switch
In general you will receive a mono sound source so that the Mono/Stereo switch can remain
set to “Mono”. When using a stereo intercom system, set the Mono/Stereo switch to “Stereo”.
Note:
If you set the Mono/Stereo switch to stereo despite a mono intercom system, you will
hear the headphone signal only on one side.
4.3.4 On/Off Button
Pressing the On/Off button activates the external audio interface of the audio box. The DANR
system is also activated which is indicated by an LED . The audio box is turned off automatically
when the surrounding is silent for a few minutes. In order to save power, however, we
recommend turning off the audio box manually.
Note:
In order to avoid operating the switch accidentally, it does not react to short pressing.
Therefore, you must press the button for approx. one second.
It is not necessary to operate the On/Off button with an external power supply via the
supplied cable with 3-pin male XLR connector (HS 800 Digital) or the 6-pin Redel
connector (HS 800 Digital 6pin). As soon as power is on (e.g. when the avionics is
turned on) the HS 800 Digital is automatically turned on.
Important:
The HS 800 Digital headset is operated as a passive headset when the audio box is
turned off.

4.3.5 Auto-Mute Button
By using the auto-mute button you can turn the auto mute function of the audio box on or
off. If a signal from the wireless receiving set or intercom system occurs, the volume of the
external device is set automatically to 10% of the volume when the auto-mute function is
activated. Shortly after the signal the volume of the external device is set to the previous level.
When the auto-mute function is activated, the status LED will illuminate. When putting the
audio box into operation the auto-mute function is activated.
Note:
When phoning we recommend deactivating the auto-mute function. Otherwise your
own voice, which is reproduced by the intercom system, can fade out the person you are
talking to.
5. How to connect external Devices to the Audio Box
5.1 Safety Information
When using a mobile phone in the cockpit you might break legal requirements. Please check the
currently valid regulations at the local responsible authorities of the appropriate country. We
recommend using a mobile phone with the HS 800 Digital only when you are on ground.
5.2 Music Players
5.2.1 Connection
Use the supplied cable with the two mini jack plugs (3.5 mm).
5.2.2 Operation
• In order to avoid damage to your hearing, make sure that the volume of the external music
player is set to minimum.
• Turn on the audio box.
• Adjust the volume of the external music player slowly to the desired level.
• Make sure that you can still hear all important sounds such as warning alarms.
5.3 Mobile Phones
Standard mobile phones can be connected to the HS 800 Digital. We cannot give any guarantee
that all mobile phones can be connected to the HS 800 Digital!
Note:
The microphone of the HS 800 Digital is powered by the on-board power supply system.
Therefore, it only works when the radio set is turned on. The headphone works
separately.
5.3.1 Connection
Use the supplied cable with the mini jack plug (2.5 mm). This plug will fit to many standard
mobile phones. If your mobile phone does not have an appropriate jack socket, you can purchase
an adapter at a shop for mobile phones and accessories.
5.3.2 Operation
In order to avoid damage to your hearing, make sure that the volume of the mobile phone is set
to minimum and adjust the desired level slowly. Deactivate the auto-mute function with the
auto-mute button .
6. How to insert/replace the Batteries
You only have to insert batteries into the audio box, when the HS 800 Digital is not powered
by the on-board power supply system.
Insert two AA batteries into the battery compartment of the audio box. As an alternative you
can use rechargeable AA batteries. Observe the polarity marks on the bottom of the battery
compartment.

7.2 HS 800 Digital 6pin
The HS 800 Digital 6pin provides a 6-pin Redel connector for the transmission of the audio
signals and the on-board power supply. Therefore, batteries are not needed.
8. How to replace the Ear Pads
9. Maintenance
• As with any equipment, which will be used in close proximity to sensitive areas of the body,
it is essential that the ear pads and headband are kept clean. Use a damp cloth for cleaning
using warm water only taking care not to allow any water drops into the transducers.
• For cleaning the wind shield remove it from the microphone and wash it under clear
running water. If necessary you can use a mild cleansing agent (e.g. washing-up liquid). Make
sure that the wind shield is completely dry before you replace it onto the microphone.
10. Service
Servicing must be carried out by qualified service personnel only or directly by:
beyerdynamic Service- und Logistik Center
August-Häußer-Str. 9, 74080 Heilbronn, Germany
Fax: [phone] – 617-252
E-mail: [email protected]
Dismantling the headset yourself will invalidate the guarantee.
If the operating control LED starts flashing slowly, the batteries still have the capacity for an
operating time of six hours. Before the next flight you should insert new batteries or rechargeable
batteries. If the operating control LED flashes faster, the capacity of the batteries is
exhausted and the batteries have to be replaced by new ones. The capacity of batteries or
rechargeable batteries is different. Furthermore, please note that rechargeable batteries can
discharge when they are stored for a longer time.
Note:
We recommend using the on-board power supply system of the aircraft to ensure the
power supply at any time. The HS 800 Digital operates also without power supply, but
the “Digital Adaptive Noise Reduction” cannot be activated any more.
7. Power Supply via the Aircraft System
7.1 HS 800 Digital
Using the supplied power cable the HS 800 Digital can be powered via the on-board power
supply system. The 3-pin XLR socket should be placed as close as possible to the jack sockets and
can be powered with 12 - 36 V DC. Make sure that the power supply from the aircraft system is
secured with a 500 mA fuse.
The pin assignment is as described below:
Pin 1 = 12 - 36 V DC, supply voltage
Pin 2 = GND
Pin 3 = not connected
• Should it become necessary, replace the ear pads.
• Pull the ear pads up and remove them from the earcups.
Attach the new ear pads to the earcups.
