Important safety instructions
1. Read these safety instructions.
2. Keep these safety instructions. Always include these safety
instructions when passing the product on to third parties.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use the product near water.
6. Only clean the product when it is not connected to the power sup-
ply system. Clean only with a dry cloth.
7. Ensure circulating ventilation. The product generates heat which
is dissipated through the housing. Install in accordance with the
manufacturer's instructions.
8. Do not install near any heat sources such as radiators, heat reg-
isters, stoves, or other products that produce heat and do not
expose to direct sunlight.
9. Do not defeat the safety purpose of the polarized or grounding-
type plug. A polarized plug has two blades with one wider than
the other. A grounding type plug has two blades and a third
grounding prong. The wide blade or the third prong are provided
for your safety. If the provided plug does not fit into your outlet,
consult an electrician for replacement of the obsolete outlet.
10. Protect the power supply cord from being walked on or pinched,
particularly at plugs, convenience receptacles, and the point
where it exits from the product.
11. Use only attachments/accessories/spare parts supplied or
recommended by Sennheiser.
12. Use only with shelves, racks, or tables that can safely support the
weight the product (see
“Specifications” on page 25).
13. Unplug the product during lightning storms or when unused for
long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is
required when the product has been damaged in any way, such as
power supply cord or plug is damaged, liquid has been spilled or
objects have fallen into the product, when the product has been
exposed to rain or moisture, does not operate normally, or has
been dropped.
15.WARNING: To reduce the risk of fire and electric shock, do not
expose the product to dripping or splashing and ensure that no
objects filled with liquids, such as vases, are placed on the
product.
16. To completely disconnect this product from the AC mains, dis-
connect the power supply cord plug from the AC receptacle.
17. The plug of the power supply cord shall remain readily accessible.

Hazard warnings on the bottom of the product
The label shown on the left is attached to the bottom of the product.
The symbols on this label have the following meaning:
Presence of uninsulated dangerous voltage within the product's
enclosure that may be of sufficient magnitude to constitute a risk of
fire or electric shock.
Read and follow the safety and operating instructions contained in
this instruction manual.
Never open the product. There is a risk of electric shock when touch-
ing live parts. There are no user serviceable parts inside the product.
Refer repairs to an authorized Sennheiser service partner.
Preventing damage to health and accidents
▷ Protect your hearing from high volume levels. Permanent hearing
damage may occur when headphones are used at high volume
levels for long periods of time. Sennheiser headphones sound
exceptionally good at low and medium volume levels.
▷ Keep the product, accessories and packaging parts out of reach
of children and pets to prevent accidents and choking hazards.
▷ Do not use the product in an environment that requires your spe-
cial attention (e.g. when performing skilled jobs).
Preventing damage to the product and malfunctions
▷ Allow the product to stand for at least 2 hours before putting it
into operation. Condensation can form inside the product if it is
moved from a cold environment to a warm environment.
Notes on the use and disposal of storage media
You can use the supplied USB flash drive for storing personal data. If
the flash drive is sold/passed on or disposed of, the data once stored
on it and then deleted using a standard delete method can be recov
-
ered with special software and be misused.
We therefore recommend using special software for secure deletion
of data to ensure that personal data is not misused.
We recommend backing up the data saved on your flash drive regu-
larly. Sennheiser does not accept liability for damage or loss of data.
Important safety instructions

over the entire frequency spectrum and extremely low harmonic
distortion
• Dynamic range of more than 120 dB, wide bandwidth and high
transient response due to short signal paths
• Outstanding ESS SABRE
32
DAC (digital-analog converter) with a
resolution of 32 bits and a sampling rate of up to 384 kHz
• Automatic adjustment of the sampling rate (44.1 kHz to 384 kHz)
• USB Audio (up to 32 Bit/384 kHz and up to DSD256)
• Can be used with up to four dynamic headphones
• 3 balanced headphone sockets (2 x 4.4 mm Pentaconn jack
socket, 1 x XLR-4 socket)
•High-quality XLR-3/¼"
(6.35 mm) jack combo socket for connec-
tion of unbalanced headphones
• High flexibility due to different connection possibilities:
– Digital inputs: S/PDIF coaxial/optical, USB

Putting the HDV 820 into
operation
Setting up the headphone amplifier
▷ Place the headphone amplifier on a flat, horizontal surface.
▷ Ensure circulating ventilation. The headphone amplifier gener-
ates heat which is dissipated through the housing.
Connecting the headphone amplifier to
audio sources
You can connect several audio sources to the headphone amplifier
and switch between these connected sources using the Input selec
-
tion rotary switch.
▷ Switch your audio sources off before connecting the headphone
amplifier.
▷ Select a suitable high-quality connection cable for your audio
source. For an optimal listening experience, Sennheiser recom-
mends using cables with a length of 3 m.
▷ To connect the headphone amplifier to your audio source, refer to
the connection diagram suitable for your audio source (see the
following chapters):
CAUTION
Risk of staining of furniture surfaces!
Varnish or furniture polish may degrade the feet of the product,

-
tion manual of your device.
If an incompatible digital audio signal is being received, the Input

driver and settings used, high-resolution music files can be repro
-
duced via the high-quality DAC (digital-to-analog converter) of the
HDV 820.

Notes on the USB audio modes
If you use standard software (e.g. Windows Media Player or Apple
iTunes), the best possible transmission mode is limited by the oper
-
ating system (the played music file is mixed with System Sounds and
adapted to the sample rate and bit depth set for the WDM driver).
For native reproduction of high-resolution files (without driver-
induced adaptation of sample rate and bit depth; 32
bits/up to
384
kHz or DSD files), you require an ASIO driver and special third-
party software, which transmits the music file natively from the
player software to the DAC of the HDV 820 (see page
12).

WARNING
Danger of hearing damage!
Before switching to a different audio source, first set the volume on
the headphone amplifier to a low level. Different audio sources and
different listening material (e.g. different pieces of music on different
CDs/sound carriers) can have widely varying signal levels. In the
case where you switch to a higher level audio source from a lower
one without first reducing the volume level this can lead to high vol-
ume levels in the headphones and could damage your hearing.
▷ Set the volume on the headphone amplifier to a low level (see
page 22) before switching to a different audio source.
