SIA-030 | Version 1

from the creator

Foreword

First of all, thank you for
choosing the Vitus Audio
SIA-030 integrated amplifier,
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”!

Unpacking the box

After you have removed the
top, it is possible to remove the
foam top and top foam corners.
Now remove the white foam
front and the wooden box sides.
Two people can carefully lift
the amplifier of the bttom foam
corners and put it directly onto
the floor.
Store the empty box and
protective foam for later use.

1. getting started

The topology of the
volume control

The topology of the volume
control used in the SIA-030 is
very different compared to the
“standard”. The SIA-030 uses a
series of fixed resistor networks
to control the volume. Relays
are used to switch between the
resistor networks. Across all
volume steps, a fixed resistor
is in series with the signal
path. This gives the best per­formance possible. When you
change volume, a different
number of shunt resistors are
used.

To prevent pop in the output,
we have chosen to first 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.

The topology of the volume
control, was updated early
2019, to be implemented in the
Masterpiece Series Linestage
(MP-L201). This offers a new
resolution of 0.5dB for every
volume step through out the
volume control, ranging from

-99dB to +18dB . Even though
the space availabe inside the
SIA-030 is extremly limitid, we
desided to integrate this new
volume control anyway. This has
only been made possible, due to
our in-house PCB manufacturing,
and resulting high level of
integration we are able to
achieve due to our control even
on this level..

2. connecting

Turning the SIA-030 on and o.

Always turn on the products
beginning from the source:

Source aIntegrated Amplifier.

Always turn off your products in
reverse order:

Integrated Amplifier a Source.

Power button can be found under bottom at center front - see
illustration on page 14. Press the power button and dimmed VA
logo will appear. Push standby button on left front, making the
front display light up together with the blue light around the power
button.

panel.)

Connect the Speaker output of
the SIA-030. Carefully connect
the mains to the amplifier,
after you have connected both
inputs and outputs.

The pre-out connectors can
be connected to a power
amplifier for biamping or an
active sub.

This is a true balanced
amplifier, DO NOT



connect the ”-“output

The elements in the
menu.

In the menu, you can modify
the settings of the SIA-030.
You do this by entering the
menu.
On page 21 you can find a
graphical reproduction of the
menu.
The sub-menus are indicated
with colours.

CLASS, MODE, COLOR,

BALANCE, INPUTS, RESET,

V.INIT, DATA and BRIGHT.

In the examples (chapter 7) you
can find various examples of
how to change the settings of
the SIA-030.

SETUP

Change the settings of the SIA-030.

CLASS

Select if the SIA-030 should
operate as a Class A or Class
AB amplifier.

Mode

Select if the SIA-030 should
operate in Classic or Rock
mode.

COLOR

Change the color of the text
and logo in the display.

BALANCE

Change the Left / Right
balance to any step between
+12 dB Left and +12 dB Right.

DATA

Shows information about this
SIA-030.

RESET

Restore the settings of the
SIA-030 to its default settings.

V.INIT

Change settings for the initial
volume step of the SIA-030.

VOL.STEP

The SIA-030 has a default volume
step of -50 dB. You can set the
volume step to a step, between

-99 dB to +18 dB. This step will be
the new default volume step. Even
after the power cord has been
disconnected the SIA-030 still starts
up in the new volume step.

REMEMBER

Set the SIA-030 to remember
the current volume step. The
SIA-030 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 SIA-030
will initiate in the volume step as
it is dened in the VOL.STEP sub­menu.

BRIGHT

Change the brightness of the
display to 0, 1, 2 or 3.

3. operation

INPUTS

Change settings for each input.

INPUT X

The SIA-030 has 5 inputs.
The settings of each individual
input can be adjusted in the
menu. The input selection is
saved automatically every 10
minutes. Each time you initialize
the SIA-030, the last saved setting
is restored. You can manually save
a setting by pressing the MENU
button down for 2-3 seconds.
When “SAVE” is shown in the
display, the setting is saved.

TEXT

By default the inputs are named
input 1, input 2, etc.
In the text-menu you can nd a list
of predened input names.
If the name of your device is not
on the list, you can choose to
make your own device name.

FIXED

Lock and unlock the volume by
switching between FIX ON/FIX OFF.

SET FIX

Set the volume of input X to a
xed dB step. Input X is now
locked to a dB step and can’t be
adjusted with the volume control.

ADJUST

Adjust the xed dB step to any
step between -99 dB and +18 dB.
This function is only available
when FIX ON is selected.

OFFSET

Oset gain setting.
Dierent sources often have
dierent output voltages.
This has a direct inuence on
the typical volume level that is
needed for a specic sound level,
hence changing between sources
can result in a high sound level
dierence. To accommodate easy
operation, we have included an
oset gain in our ampliers - it
simply osets the volume starting
point at a specic volume to match
the source. The oset-value can be
set from -12 dB to +12 dB.

SENS

Devices can have dierences in
output level. You can adjust the
sensitivity of each input between
≤ 2 Vrms, ≤ 4 Vrms, ≤ 8 Vrms to
minimize these dierences and to
prevent clipping of the input.
The sensitivity level needs to be
higher than the input level.

USED

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.
