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

About this manual

This is your RI-100 owner’s

manual. The following pages

will describe, as clearly as

possible, how to get your RI-

100 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 coused

to the unit by ignoring

this information might

invalidate the warranty.

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.

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.

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.

Store the empty box and the

protective foam for later use.

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.

2. connecting

Connecting the RI-100

Place the RI-100 on its shelf.

Connect all the sources to the

inputs of the RI-100, (labelled

INPUT 1 to 5 on the rear

panel.)

Connect the Speaker output of

the RI-100. Carefully connect

the mains to the amplifier,

after you have connected both

inputs and outputs.

This is a true balanced

amplifier, DO NOT connect

the ”-“output (Figure 3) to

any ground source, including

chassis or signal ground, this

will damage the amplifier.

The pre-out connectors can be

connected to a power amplifier

for biamping or an active sub.

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

On page 20 you can find a

discription of the elements in

the menu. In the Appendix (

chapter 7 page 30-41 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.

(Example 1 page 32)

Reset

Restore the settings of the RI-100

to its default settings.

(Example 2 page 33)

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.

(Examples 11 and 12

on page 40 and 41)

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.

In the example on page XX

we will show you how you can

change the offset values

(Examples 8 and 9 on pages 39

and 40)

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.

(Example 10 page 39)

3. operation

RI-100 | v 06.09.2011

3. operation

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.

(Examples 3 and 4

on pages 34 and 35)

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.

(Examples 5 and 6

pages 36 and 37)

VOL.STEP

The RI-100 has a standard volume

step of -42 dB. You can set the

volume step to a step, between

-99.0 dB to +6dB.This step will be

the new volume step. Even when

after the power cord has been

disconnected the RI-100 still starts

up in the new volume step.

REMEMBER

Set the RI-100 to remember the

current volume step. The RI-100

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 RI-100

will initiate in the volume step as it

is deﬁned in the V.INIT sub-menu.

locked to a dB step and can not

be adjusted with the volume

control)
