MACHINE PRESENTATION
Le Nanopre est une machine Dub box complète. Originellement conçue pour tout amateur de
Reggae, de Dub ou de vinyles, il peut être utilisé pour transformer et améliorer n'importe quel type de
musique.
Pour une utilisation à la maison, en émission radio, en mix Live ou comme un vrai préamp Sound-
System, cette petite machine vous permettra de :
Séparer les différentes fréquences et instruments de la musique, augmenter, atténuer ou couper
individuellement chacune d'entre elles via l'isolateur interne 4-voies.
Utiliser un microphone externe, avec l'entrée XLR, les réglages de gain et d'envoi d'effet dédiés.
Utiliser un lecteur vinyle via l'entrée Phono, ou n'importe quelle autre niveau ligne, avec un
réglage dédié du Gain et d'envoi d'effet.
Ajouter de l'effet avec la Dub Siren interne (design exclusif, trouvable nulle part ailleurs).
Utiliser une Dub Siren externe ou toute autre machine génératrice de son (Effet, Sampleur, etc.)
en utilisant l'entrée "Ext. Siren"
Ajouter un effet d'écho sur n'importe quelle des sources ci-dessus en utilisant le Dub Delay
interne.
Ajouter un effet externe (de votre choix) sur n'importe quelle des sources ci-dessus (en utilisant
la fonction "Envoi d'effet" et "Retour d'effet")
Améliorer et donner une couleur au son de votre musique avec les filtres paramétriques internes.
Utiliser les 4 sorties séparées pour relier jusqu'a 4 amplificateurs différents, créant un vrai
système actif 4-voies.
Utiliser la sortie "Full Range" pour relier la machine à n'importe quel mixeur standard,
amplificateur ou moniteurs studio.

QUICK START
For a correct use of your NANOPRE, please read the instructions below:
1. This NANOPRE must be plugged into a LINE input of your mixer or preamp. An effect processor
can be plugged between your NANOPRE and the LINE input of your mixer, only if the input of
your effect processor is also a LINE type input. In any case, do not plug your NANOPRE in a
Microphone input or it may damage it. Please see the « Typical wiring » section for a more
detailed description of the possible wirings.
2. In you use the NANOPRE with a DJ mixer, a [MONO JACK 6.35mm] to [2 x RCA (Cinch)] is
necessary.
3. Before powering the NANOPRE, ensure that the Volume potentiometer is at the minimum
position. Put your NANOPRE on and progressively increase the volume until you have a sound.
4. Only use the provided power supply block.

BACK PANEL FUNCTIONS & CONNECTORS
Tha rear panel is composed of multiple connectors, directly linked with certain functions from
the front panel.
A detailed description of all the connectors is given below.
The main wiring diagrams have a dedicated section later in this document.
BLOC 1 : SEPARATED OUTPUTS & FULL RANGE OUPUT
As the NANOPRE has an internal 4-way active filter, you can use the separated outputs of the
Nanopreamp in case of a multi-amplification system.
In case of a simpler setup, for recording or any other application where only a Complete, Full
range signal is needed, the Full Range output can be used..
FONCTIONS
UTILISATION
SUB
SUB separated output. Only the signal of the SUB output of the 4-way filter is
present on this output.
6.35mm Unbalanced MONO JACK type Connector.
BASS
BASS separated output. Only the signal of the BASS output of the 4-way filter
is present on this output.
6.35mm Unbalanced MONO JACK type Connector.

NANOPRE –User Manual

11
MID
MID separated output. Only the signal of the MID output of the 4-way filter is
present on this output.
6.35mm Unbalanced MONO JACK type Connector.
TOP
TOP separated output. Only the signal of the TOP output of the 4-way filter is
present on this output.
6.35mm Unbalanced MONO JACK type Connector.
FULL RANGE
This output is the sum of all the other outputs. A signal containing the integral
audio spectrum is present on this output.
6.35mm JACK type Connector
2 possibilités de sortie sur ce jack :
oSortie « double mono » asymétrique (STEREO JACK).
oSortie mono symétrique (TRS JACK).
La modification pour le passage d’une possibilité de sortie à l’autre est
expliquée dans le paragraphe «Modification / Personnalisation ».
BLOC 2 : FX SEND & RETURN
The Nanopreamp has an internal Delay module (DUB DELAY). However, it is possible to plug an
external effect module.
Its use can be coupled to the internal Delay (Internal delay in “On” positon). In case the internal
delay would be in the “OFF” position, only the external effect module will be active.
In all the cases, the effect return volume (internal and/or external) will be set by the same
potentiometer on the front panel, wich is “FX VOL” knob of the “Dub Delay” introduced in the previous
section.
FONCTIONS
UTILISATION
FX SEND
Output of the effect send. This output can be connected to the LINE input of
an external effect module.
6.35mm Unbalanced MONO JACK type Connector.
FX RETURN
Input to plug the output of the external effect module.
LINE type input.
6.35mm Unbalanced MONO JACK type Connector.
BLOC 3 : EXTERNAL SIREN
The Nanopreamp has an internal Dub Siren. However, you can add an External Dub Siren or any
other Sound Generator by connecting it to this Input.
In case the External Dub Siren is plugged on this input, the volume and the effect send of it will
be the controlled by the same potentiometers used to control the internal siren.
This input is a 6.35mm Unbalanced MONO JACK type Connector input.

12
BLOC 4 : PHONO & LINE INPUTS
Two audio sources, a Turntable / Recordsplayer or a CD Player (Laptop, or any other LINE type
source) can be plugged in the same time on the Nanopreamp. The switch in the front panel allowing
choosing one of these two sources.
FONCTIONS
UTILISATION
PH
Made by two Cinch (RCA) connectors and a GND pin to clip the ground wire,
this input is a PHONO type one and allows to connect a Turntable.
LINE
Made by two Cinch (RCA) conenctors, this input is a LINE type inupt and
allows you to connect any LINE type equipment (CD Player, Laptop, etc)
BLOC 5 : MICROPHONE INPUT
This 3-pin XLR Balanced connector is an input dedicated to use a Microphone.
There is no +48V power generator in the Nanopreamp, thus you cannot use a microphone which
needs a +48V voltage to operate.
BLOC 6 : POWER SUPPLY
The power supply connector is a BARREL 2.1 x 5.5 mm, allowing to plug the power supply bloc
provided with the Nanopreamp.
The power supply bloc is specifically designed for the Nanopreamp. Please refer to the end of
this document to see the exact specs.
NOTE
1. Do not connect another power supply block.
2. In case of doubt, please contact the KLEMENTZ team at the address give at the end of this
document.

MODIFICATIONS / CUSTOMIZATIONS
The user is not allowed to proceed to any tweaks or mods to the machine without the explicit
allowance or request from the builder, or it will void the warranty.
It is possible to customize and change the cut-off frequencies on request while ordering, and
later when the machine has been bought, please contact us.
However, we do propose 2 customization options that allow the user to change these few
configurations at any moment.
BEFORE OPENING
It is mandatory to strictly follow the method described below to avoid any damage to the unit while
changing the configuration:
STEP 1
Turn the machine Upside down and locate the 4 screws on the bottom of it. Then, gently unscrew these
screws and gently remove the bottom part of the unit, while taking care to remember the way it was set
before you removed it, and finally access the inside of the unit.
STEP 2
Locate the part of the machine where the modification is to be made, then remove the blue jumper(s), if
they’re glue together, remove the whole set of glued jumpers. Once they’re removed you can then
separate them and remove the glue.
Once the jumper(s) are removed, replace them to have the desired setup (according to the tables
below)
STEP 3
Once the jumpers are set into their sockets (ensure they’re pushed to the maximum), you can close
back the machine by reinserting the bottom side in the same way as it was before you removed it.
