FROM THE CREATOR
Foreword
First of all, thank you for choosing the Vitus Audio RD-101
Reference DA Converter, 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.
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 ampliers. 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 ampliers do not
“focus” on any specic frequencies - i.e. no extension of top or bass,
which of course results in high clarity of the midrange since
it’s “naturally present”!

INTRODUCTIONINTRODUCTION
This is your RD-101 owner’s manual. The following pages will,
as clearly as possible, describe how to get your RD-101 operating
quickly and easily. Although some operations are self-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 by sending an email with your nding to: sales@avagroup.nu
Reference Series is your entry point to the world of Vitus Audio.
The components in this series are cost-optimised versions of the
products in our Signature Series. Although the cost is lower, this
does not mean we have compromised on results. As with every Vitus
Audio product, the sound you experience remains breathtaking.

1. GETTING STARTED1. GETTING STARTED
What’s in the box, and how
to correctly unpack it
RD-101 device overview
Gently cut open the tape on the top of the box, making sure not
let the knife protrude too much. Open the box and remove the
foam top with all the included accessories. Next, remove the 4
foam corners from the front and back of the product. With two
people, carefully lift the amplier out of the box.
Store the empty box and protective foam for later use.

The topology of the volume control used in the RD-101 is very
dierent compared to the “standard”. The RD-101 uses a series of
xed resistor networks to control the volume. Relays are used to
switch between the resistor networks. Across all volume steps, a
xed resistor is in series with the signal path. This gives the best
performance possible. When you change volume, a dierent
number of shunt resistors are used.
The topology of the volume control
To prevent pop in the output, we have chosen to rst add the new
shunt resistors, and then wait a short time, before removing the
unused shunt resistors at the new volume step. This will give a minor
fall in volume before settling at the new volume step. It takes very
little time to get used to this type of operation of the volume, and
it will give you superior sound quality over the traditional digital
and analogue potentiometers.

You can modify the settings of your RD-101 by entering the menu and selecting
the options you require. Refer to the menu structure diagram on page 21 for specific
information.
The sub-menus are highlighted in different colours.
SETUP, OUTPUT, REMOTE, AutoStb, RESET, V.INIT, BP VOL, LOGO, BRIGHT, INPUTS
See chapter 7 for options on modifying settings.
SETUP
Change the settings of the RD-101.
OUTPUT
Here you can switch between RCA OUT and XLR OUT.
REMOTE SETTINGS
The RD-101 is standard 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 than it is recommended that you pair the remote(s)
with their devices.
REMOTE ID
Show the ID of the remote.
UNPAIR
Un-pair the remote and the RD-101 by removing the REMOTE ID.
DATA
Shows information about this RD-101.
AutoStb
Choose if the product should automatically enter standby mode
afterthe buttons on the remote or on the front of the unit haven’t
been used for X minutes.
RESET
Restore the settings of the RD-101 to its default settings.
V.INIT
Change settings for the initial volume step of the RD-101.
The RD-101 has a default volume step of -50 dB. You can set the
volume step to a step, between -99.0 dB to +12 dB.This step will
be the new volume step. Even when after the power cord has
been disconnected the RD-101 still starts up in the new volume step.
BP VOL
Switch between BP OFF (enable volume control) or BP ON (disable
volume control).
LOGO
Turn ON/OFF the VA logo on the front panel
BRIGHT
Change the brightness of the display to 0, 1, 2 or 3.
INPUTS
Change settings for each input.
INPUT (1-5)
The RD-101 has 5 analog inputs.
The settings for each individual input can be adjusted in the menu.
The input selection is saved automatically every 10 minutes.
Each time you initialise the RD-101 the last saved setting is restored.
You can manually save a setting by pressing the MENU button
down 2-3 sec. When “SAVE” is shown in the display, the setting
has been saved.
STREAMER
Here you can set the RD-101 to automatically check for rmware
updates for the streamer. In the streamer settings the update check
can be enabled/disabled. (note: all rmware updates made available
are tested and approved by Vitus Audio).
INPUT NAME SETTINGS
By default, the inputs are named DIG 2/3/4/5, USB and Streamer.
In the text-menu you can nd a list of predened input names.
If the name of your device is not in the list, you can choose to make
your own device name.
ADJUST
Adjust the xed dB step to any step between -89 dB and +13dB.
This function is only available when FIX ON is selected.
SET FIX
Lock and unlock the volume on a specied input by switching
between FIX ON/FIX OFF.
This feature can be used to congure a home theater bypass input,
if the amplier is used with a surround processor. Input X is now
locked to the SET FIX dB step and can’t be adjusted with the
volume control.
OFFSET
Oset volume setting.
Dierent sources often have dierent output voltages. This has
a direct inuence on the typical volume level that is needed for a
specic sound level, hence changing between sources can result in
a high sound level dierence. To accommodate easy operation, we
have included an oset volume in our ampliers – it simply osets
the volume starting point at a specic volume to match the source.
The oset-value can be set from -12 dB to +12 dB.
SENS
Devices can have dierences in output level. You can adjust the
sensitivity of each input between ≤ 2 Vrms, ≤ 4 Vrms, ≤ 8 Vrms to
minimize these dierences and to prevent clipping of the input.
The sensitivity level needs to be higher than the input level.
TEXT
Lets you change the name of a specied input.
By default the inputs are named input 1, input 2, etc. A list of
predened input names can be found in the text-menu. If the name
of your device is not on the list, you can choose to make your own
device name.
USED
Activates or disactivates specied 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 used input.
