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.
Dans la suite du document, chacune des fonctions sera détaillée séparément.

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.

BLOC 1 : PHONO / LINE PREAMPLIFIER
FUNCTIONS
USAGE
LN /PH
Switch used to select the main signal / music source :
In high position, the LINE input is selected (CD player, Laptop, or any
other line level source)
In low position, the PHONO input is selected (Turntable)
MUSIC VOL
Potentiometer setting the input level of the selected source (Phono or Line):
If it’s at the minimum (fully anti-clockwise), the volume is the lowest.
If it’s at the maximum, the volume will be higher.
FX SEND
Rotary potentiometer setting the level of effect send of the Music signal.
BLOC 2 : MICROPHONE PREAMPLIFIER
FUNCTIONS
USAGE
MIC VOL
Potentiometer setting the input level of the Microphone:
If it’s at the minimum (fully anti-clockwise), the volume is the lowest.
If it’s at the maximum, the volume will be higher.
FX SEND
Rotary potentiometer setting the level of effect send of the Microphone.
BLOC 3 : DUB SIREN
FUNCTIONS
USAGE
TONE
Rotary potentiometer allowing to set the pitch of the sound of the Dub Siren :
If it is at the minimum (fully anticlockwise), the pitch of the sound is low.
If it is at the maximum, the pitch of the signal is high.
FX SEND
Rotary potentiometer setting the level of effect send of the Dub Siren.
SPEED
Rotary potentiometer allowing setting the oscillation speed of the LFO.
If it is at the minimum (fully anticlockwise) the oscillation speed will be
low and the modulation will be slower.
If it is at the maximum, the oscillation speed will be fast and the
modulation will be fast as well.
VOL
Rotary potentiometer allowing setting the output volume of the Dub Siren.

SHAPE
Switch selecting the mode (modulation waveform) of the Dub Siren
TRIG
Push button triggering the sound output of the dub siren.
BLOC 4 : 4 WAY CROSSOVER
The Nanopreamp has an internal active filter composed of 4 ways: SUB / BASS / MID and TOP.
Each way of the active filter is constituted of the following elements:
-A volume potentiometer, with which the volume of a particular frequency band can be set
-A kill switch which allows enabling or disabling (mute) the output of a particular band.
-A signal LED
BLOC 5 : DUB DELAY
FUNCTIONS
USAGE
TIME
Rotary potentiometer allowing setting the time between two repeats.
When in minimum setting (fully anti-clockwise), the time between two
repeats will be very short and thus the repeat time will be fast.
If it is at the maximum, the repeat time will be long and thus repeat
speed will be slow.
FEEDBACK
Rotary potentiometer allowing setting the gain between each repeat.
When set at minimum (full anti-clockwise), there will be only one repeat.
When set at the maximum, the level will increase at each repeat.
FX VOL
Rotary potentiometer allowing setting the level of the effect return.
If it’s at the minimum (fully anti-clockwise), the volume is the lowest.
If it’s at the maximum, the volume will be higher.
ON/OFF
Switch used to enable or disable the internal dub delay:
When set in high position, the internal dub delay is not working (OFF)
When set in low position, the internal dub delay is powered (ON)
