from the creator
Foreword
First of all, thank you for
choosing the Vitus Audio
SS-025 stereo 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”!
Hans Ole Vitus

introduction
This amplifier is
VERY heavy –
make sure to be
at least two people
to unpack the unit.
You might damage
both your back and
the amplifier 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.

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 amplifier from
a cold place to a warm
place.

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
amplifier. 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 SS-025.
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.

Mains fuse
The mains fuse is accessible
from the outside of the
amplifier. You will find the
mains fuse, just below the
power inlet. If the fuse blows,
then you can easily replace
it. The fuse only blows on the
occurrence of power surges
or if there is a fault in the
unit. Normally power surges
cause no other damage other
than blowing the fuse. When
the fuse blows repeatedly on
replacement, then the unit
most likely has a malfunction.
In case of malfunction the
unit must be returned to Vitus
Audio for repair.
Fuse type:
20x5mm 6,3A T(230V) /
10A T(115V) / 12A T(100V)
HRC fuse
Replacing the fuse with a fuse
of a type and rating different
from the original fuse, might
result in damage to the unit
and injury to you (the user).
Damage to the unit as a result
of wrongly replacing the
mains fuse, will invalidate the
guarantee.
For an explanation of how to
replace the fuse see chapter 4
“replacing a blown fuse”.
