SCD-025 | Version 1
from the creator
Foreword
First of all, thank you for
choosing the Vitus Audio
SCD-010. We know you will
enjoy it for many years to
come. When purchasing a
Vitus Audio product, you
are guaranteed a musical
performance, which far-
exceeds the current musical
standards. Vitus Audio
is dedicated to musical
performance rather than
technical details and high
performance measures.
We believe that many
manufactures are blinded by
the current available theory,
instead of looking for new
answers.
At Vitus Audio everything
works until proven not to.
This way we always try to
push the limits and explore
the unexplored. As a result
of this, many of the solutions
we use today are considered
to be “impossible to ever
get working”, however they
have convinced many people
and reviewers world wide
of the opposite. Before any
of our new topologies are
implemented in our products,
they are carefully reviewed by
our dedicated listening panel.
This way we can guarantee
the correct level of musically
performance and robustness.
Generally we’re after super
neutral, super detailed and
super dynamic reproduction
without “loosing” the nerve
in the music, which often is a
drawback of many high end
systems. Our real strongholds
are complete silence,
unbelievable depth and width
in the soundstage resulting
in a far more open sound
with higher resolution -you
could say, closer to the artist.
As a result of the above, our
electronics do not “focus” on
any specific frequencies - i.e.
no extension of top or bass,
which of coarse results in high
clarity of the midrange since
it’s “naturally present”!
Hans Ole Vitus

explanatory, we strongly
suggest you read this manual
to avoid any damage to the
unit. The manual is designed
to be helpful. If there are
points you feel we could cover
better, or that we have missed
out – please tell us.
Important
information
is presented like
this. Ignoring this
information may cause
damage to you or the

to the unit by ignoring
this information might
invalidate the warranty.
Introduction to the
Signature Series
The Vitus Audio Signature
Series is a true high-end series
of products, which is build on
our true dedication to neutral
music reproduction. Every
detail is carefully thought
through, and all choices made
during development, where
based purely on listening, and
not measuring. Only the best
available materials are used to
ensure an overall quality which
will last for many years, when
treated right.

Unpacking the box
After you have opened the
top, it is possible to remove
the top protective foam which
gives you direct access to the
unit.
In the top you will find the
remote, the power cord and
brochures.
Now remove the side
protective foam, this will make
it easier to grab hold of the
unit.
Two people carefully lift the
amplifier out of the box, and
put it directly onto the floor.
Store the empty box and the
protective foam for later use.

Handling the unit
This unit is VERY
heavy – make sure
to be at least two
people to unpack the
unit. You might damage
both your back and
the unit if extra care
is not applied. Vitus
Audio A/S cannot
be held responsible
for any damage that
is a consequence of
uncareful handling of
the unit.

Differences in
temperature
After unpacking
allow 24 hours
for the product to
reach room temperature
before connecting up
and switching on. This
is to allow condensation
to dissipate, which
might otherwise
cause damage to the
electronics. Remember
also that condensation
can form when you
move the unit from a
cold place to a warm
place.

Turning the SCD-025 on and off.
Always turn on the products
beginning from the source:
CD player apre-amplifier apower amplifier.
Always turn off your products in
reverse order:
Power amplifier apre-amplifier aCD player.

Not following this procedure, may cause damage
to any of your products/speakers. Damage caused
to any of your products/speakers by not following
this procedure will invalidate the warranty.
External interference
It is important to remember
that all equipment which is
connected to the mains is
a potential source of hum
and interference and may
radiate both electrostatic or
electromagnetic radiation. In
addition, the mains will also act
as a carrier for many forms of
RF interference generated by
electric motors, air-conditioning
units, thyristor light dimmers
etc. Unless the earth system is
clean, all attempts to improve
hum noise levels will be futile.
In extreme cases there will be
no alternative but to provide
a completely separate and
independent `technical earth'
to replace the incoming 'noisy
earth'. However, always consult
your local electricity supply
authority to ensure that safety
regulations are not being
infringed.
Always follow this procedure.
1. Turn the SCD-025 off.
2. Disconnect the mains power supply
(take the andromeda cable out).
3. Remove the Mains Cable
4. Move/Transport the SCD-025
5. Allow 24 hours for the SCD-0251 to
reach room temperature.

1. Place the SCD-025 on the
floor.
2. Allow 24 hours for the
product to reach room

3. Connect all the sources to
the inputs of the SCD-025.
4. Connect the output of the
SCD-025 to the amplifier.
5. Connect the mains to the
SCD-025.
Volume control
The volume control is turned
off by default. When you use
the CD-player together with
a preamplifier or integrated
amplifier, it is recommended
that the volume control of the
CD-player is bypassed.
If you want to remove the
volume bypass, see example
“turning volume bypass off” in
the example in chapter 7.

a power source and the PC
and the SCD-025 have to be
connected with an USB cable.
On the CD you can find
the installation files for the

SCD-025 | Version 1
Setting up the Media
player.
We recommend that you use
a media player that can be set
to have its output in Kernel-
streaming mode.
Do not use Windows Media
Player. Windows Media
Player does not support
Kernel Streaming.
The output of the media-
player has to be set to Kernel
streaming and Vitus Audio
Interface.
Always close the media-
player program before
connecting or disconnecting
the SCD-025 to the
computer.
In chapter 7 we will show how
to set up Foobar2000 a free
mediaplayer.
Kernel Streaming
Kernel Streaming or Direct
Kernel streaming (Direct KS)
is a technique that supports
kernel-mode processing of
streamed data. It enables
efficient real-time streaming
for multimedia devices such
as sound cards and TV tuner
cards. Kernel streaming allows
a device driver to create Direct
Show-like filters and pins in
kernel mode, providing access
to hardware, lower latency
communication and still be
used within a Direct Show filter
graph.
