from the creator
Foreword
First of all, thank you for
choosing the Vitus Audio
MP-I201 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 bas,
which of course results in high
clarity of the midrange since
it’s “naturally present”!
Hans Ole Vitus

About this manual
This is your MP-I201 owner’s
manual. The following pages
will describe, as clearly as
possible, how to get your MP-
I201 operating fast and simple.
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.
Important
information is
presented like
this. Ignoring this
information may cause
damage to you or the
unit. Damage caused
to the unit by ignoring
this information might
invalidate the warranty.

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.

1. getting started
1. getting started
The topology of the volume
control used in the MP-I201
is very different compared
to the “standard”. The MP-
I201 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
only 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 potentio meters.
