from the creator

Foreword

First of all, thank you for

choosing the Vitus Audio

RI-100 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”!

Introduction to the

Reference Series

The Vitus Audio Reference

Series is a true high-end series

of products, which is build on

our true dedication to neutral

music reproduction. Every

detail is carefully thought

through, and all choices made

during development, where

based purely on listening, and

not measuring. Only the best

available materials are used to

ensure an overall quality which

will last for many years, when

treated right.



RI-100 | Version 1

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

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 RI-100.

Two people carefully lift the

amplifier out of the box, and

put it directly onto the floor.

RI-100 | Version 1

1. getting started

The topology of the volume

control used in the RI-100 is

very different compared to the

“standard”. The RI-100 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 per-

formance 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 potentiometers.

The topology of the

volume control.

The menu structure

You can modify the settings

of the RI-100. You do this by

entering the menu. On page

23 you can find a graphical

reproduction of the menu.

The sub-menus are indicated

with a colour.OUTPUT RESET

REMOTE, V.INIT and INPUTS

In the Appendix ( chapter 7

of the manual ) you can find

various examples of how to

change the settings of the

RI-100.

Selecting output

This option is only available

when you have the optional

headamp interface module

installed in the RI-100.

Here you can switch

output from SPEAKERS to

HEADPHONES.

Reset

Restore the settings of the RI-100

to its default settings.

Input settings

The RI-100 comes with 5

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 initialize the

RI-100, 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.

Input name settings

As a standard, the inputs are

named input 1, input 2, etc. 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.

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 amplifiers – 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.

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.

Remote settings

The RI-100 is standard shipped

with a Apple Remote.

The Apple remote that

comes with the RI-100 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.

Volume settings

The RI-100 starts up in

the same volume step on

initialization. You can select

in which volume step, the RI-

100 should initialize. You can

set the initial volume step in

the menu, to a step between

-99.0dB and +6dB.

You can also set the initial

volume-step to “REMEMBER”.

When you set the RI-100

to “REMEMBER”, then it

remembers the volume step

from when it was put to

standby. Next time the RI-100

leaves standby, it will start in

this volume step.

Safety notice

The Vitus Audio RI-100

contains no user serviceable

parts except from the mains

fuse. Do not attempt to open

the case. There are potentially

dangerous voltages present

inside. Should your RI-100

show signs of malfunction,

then please contact your

dealer or Vitus Audio.

Mains supply voltage

Any unit may be set for

operation in 100V, 115V or

230V A.C. Units are shipped

set for the mains supply

voltage according to the

destination. The voltage

setting can be updated later

by your dealer, if necessary.

Maintenance

Vitus Audio products are

designed to run for many years

without the need for regular

maintenance. Our products

contain no user serviceable

parts except from the mains

fuse. Should your RI-100 show

signs of malfunction, please

contact your dealer or Vitus

Audio.

RI-100 | Version 1

4. operation & service

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”.

Changing the offset-

gain of the inputs.

You can set different offset-

values for the different inputs.

You actually adjust the gain

of one individual input. This

will reduce the differences

in volume, when you switch

from one input to another. The

offset-value can be set from

-12 dB to +12 dB.

You can not change the offset

gain when you selected FIX

ON.

The following example

illustrates how to change the

offset-values: The signal on

the source using line 2 is 3 dB

higher than the signal on the

source using line 1.

We will reduce the differences

in volume between input 1

and input 2 by lowering the

offset gain of line 2 with 3 dB.
