from the creator
Foreword
First of all, thank you for
choosing the Vitus Audio
RD-101 DAC, we are sure you
will enjoy it for many years
to come. When purchasing
a Vitus Audio product, you
are guaranteed a musical
performance,
which 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 amplifiers. 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 amps do not “focus” on
any specific frequencies - i.e.
no extension of top or bass,
which of course results in high
clarity of the midrange since
it’s “naturally present”!
Hans Ole Vitus

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 RD-101. Two people
carefully lift the unit out of the
box, and put it directly onto
the floor.
Store the empty box and the
protective foam for later use.

RD-101 | Version 1
You can modify the settings
of the RD-101. You do this by
entering the menu. You can
find a graphical reproduction
of the menu. The sub-menus
are indicated with a colour.
OUTPUT RESET REMOTE,
V.INI/BP VOL, BRIGHT and
INPUTS.
In the Appendix ( chapter 7
of the manual ) you can find
various examples of how to
change the settings of the RD-
101.
Remote settings
The RD-101 is shipped with a
Apple Remote.
The Apple remote that
comes with the RD-101 can
be used on all Reference
devices. If you own two (or
more) reference devices then
it is recommended that you
pair the remote(s) with their
devices.
Volume settings
The RD-101 starts up in
the same volume step on
initialization. You can select
in which volume step, the RD-
101 should initialize. You can
set the initial volume step in
the menu, to a step between
-121.5 dB and 0 dB.
You can also set the initial
volume-step to “REMEMBER”.
When you set the RD-101
to “REMEMBER”, then it
remembers the volume step
from when it was put to
standby. Next time the RD-101
leaves standby, it will start in
this volume step.
3. operation
RD-101 Menu: introduction

19
RD-101 | Version 1
Input settings
The settings for each individual
input can be adjusted in the
menu.The input selection is
saved automatically every
10 minutes. Each time you
initialize the RD-101, the last
saved setting is restored.
Input name settings
By default, the inputs are
named DIG 2/3/4/5, USB and
Streamer. In the text-menu you
can find a list of predefined
input names. If the name of
your device is not in the list,
you can choose to make your
own device name.
Streamer
Here you can set the RD-101
to automatically check for
firmware updates for the
streamer. In the streamer
settings the update check can
be enabled/disabled.
(note: all firmware updates
made availible are testet and
approved by Vitus Audio).
Input gain settings
Offset gain setting / Sensitivity
setting. Different sources often
have different output voltages.
This has a direct influence on
the typical volume level that
is needed for a specific sound
level, hence changing between
sources can result in high
sound level differences. To
accommodate easy operation,
we have included a gain (or
as some prefer to call it –
sensitivity setting) in our DACs
– it simply sets the volume
starting point at a specific
volume – to match the source.
The offset-value can be set
from - 12 dB to +12 dB in steps
of 0.5 dB.
Disabling inputs
If you only use some of the
inputs, it is possible to disable
the inputs that are
not used. Using the “Input”
button, the system skips the
disabled inputs, and jumps to
the next input.

the new volume step. Even when
after the power cord has been
disconnected the RD-101 still
starts up in the new volume step.
REMEMBER
Set the RD-101 to remember
the current volume step. The
RD-101 will start up in this volume
step when it leaves standby.
This volume step however is not
remembered when the power
cord is removed. Then the RD-101
will initiate in the volume step as it
is defined in the V.INIT sub-menu.
