Selecting a Volume Pedal Curve
There are three Volume pedal response
curves for you to choose from.These deter-
mine the speed at which the volume changes
as the Volume pedal is operated, as shown
below.
Pedal position
Volume
Up
Quiet
Down
Loud
1

Curve #1: The volume changes slowly in the
upper range of the pedal’s travel; quickly in
the lower range.
Curve #2: With this standard curve, the
volume changes throughout the pedal’s
travel.This is the initial setting.
Curve #3: The volume changes quickly in the
upper range of the pedal’s travel; slowly in the
lower range.
Re-selecting the default curve
1.Turn off the connected device.
2.While holding down the VC-12’s BANK
UP switch and switch #1, #2, or #3, turn
on the connected device.
The number of the selected curve (C1, C2,
or C3) appears on the BANK display for
one second. Since the VC-12 remembers
which volume curve you select, there’s no
need to select it again the next time you
use your VC-12.
User Hint
The default curve (No. 2) is the standard
Audio Taper pot curve, as used in most
commercial volume pedals, and as such is
extremely useful for most purposes.By
selecting either of the other two curves you
can fine-tune the operation of the pedal to
what feels most comfortable to yourself. As
with most things in life, please feel free to
experiment, as only you know what suits
you best.

présente comme suit. L’affichage indique
alors le nom de la note que tu accordes.
Accord normal Accord silencieux
Tant que ton ampli Valvetronix est en mode
manuel, l’affichage se présente comme suit
et le VC-12 se comporte comme en mode
d’activation/de coupure d’effet.
3. Commutateur et diodeTAP
Ce commutateur permet de régler le temps
de retard. Le VC-12 calcule le temps de
retard en se basant sur l’intervalle entre tes
deux dernières pressions (“Tap”).
Remarque: Tu perds ce réglage du retard
quand tu changes de mémoire ou lorsque tu
mets l’appareil connecté hors tension. Si tu
veux conserver ce réglage, mémorise-le sur
l’appareil connecté.Pour en savoir plus,
consulte le mode d’emploi de l’appareil en
question.
1. Commutateurs BANK UP/DOWN
Ces commutateurs servent au choix des
banques.
En mode de sélection de mémoire (Channel
Select) et d’activation/de coupure d’effet
(Effect On/Off), chaque pression sur le
commutateur UP sélectionne la banque
suivante. Le commutateur DOWN sert lui à
choisir la banque précédente.
Tant que ton ampli Valvetronix est en mode
manuel, ces commutateurs ne produisent
aucun effet. Pour savoir comment annuler le
mode manuel de l’ampli, consulte son mode
d’emploi.
2. Affichage BANK
En mode de sélection de mémoire, cet
affichage indique le numéro de la banque de
mémoires choisie.

Ce commutateur active/coupe la fonction
d’accordeur du pédalier.
La diode centrale s’allume lorsque l’accord
est correct. Pendant l’accord, le nom de la
note détectée apparaît à l’écran BANK.Pour
en savoir plus, lis “Utiliser la fonction d’accor-
deur” à la page 21.
5. Commutateur RECALL
En mode de sélection de mémoire, ce com-
mutateur rappelle la dernière mémoire
choisie.Tu peux t’en servir pour alterner
rapidement entre les mémoires de banques
différentes.Imaginons par exemple que tu
choisisses la mémoire 4-2 puis la mémoire 2-
1. Dans ce cas, tu peux charger instantané-
ment la mémoire 4-2 en appuyant simple-
ment sur le commutateur RECALL.
Le commutateur RECALL ne fonctionne pas
en mode d’activation/de coupure d’effet ni en
mode manuel.
6. Commutateurs 1–4 et diodes d’effets
En mode de sélection de mémoire, ces
commutateurs servent au choix des mémoi-
res.Les diodes 1–4 indiquent la mémoire
actuellement sélectionnée.Pour en savoir
plus, lis “Mode de sélection de mémoire” à la
page 19.
En mode d’activation/de coupure d’effet, ces
commutateurs permettent d’activer et de
couper individuellement les sections d’effets
Pedal, Modulation, Delay et Reverb.
Les diodes 1–4 indiquent les effets actifs.
Quand ton ampli Valvetronix est en mode
manuel, ces commutateurs se comportent
comme en mode d’activation/de coupure
d’effet.
7. Commutateur et diode CHANNEL–FX ON/OFF
Ce commutateur sert à alterner entre le
mode de sélection de mémoire (Channel
Select) et le mode d’activation/de coupure
d’effet (Effect On/Off).
En mode de sélection de mémoire, l’écran
BANK indique le numéro de la banque de
mémoires choisie.
En mode d’activation/de coupure d’effet, la
diode FX ON/OFF est allumée et l’écran
BANK se présente comme suit.
8. Pédale d’expression et commutateur
de pédale
La pédale d’expression permet de piloter
l’effet assigné sur l’appareil branché.Pour en
savoir plus sur les effets pilotables, consulte
le mode d’emploi de l’appareil connecté.
Le commutateur de la pédale permet d’acti-
ver/de couper l’effet assigné sur l’appareil
branché.La diode en haut à gauche de la
pédale s’allume quand celle-ci permet de
piloter un effet.
Si tu as branché le pédalier à un ampli
Valvetronix, son fonctionnement diffère de
la description ci-dessus.Voici dans ce cas
comment fonctionnent la pédale d’expres-
sion et son commutateur.
Pédale d’expression
• Quand l’effet VOX WAH (effet Pedal) est
selectionné: pilote l’effet WAH
• Quand l’effet U-VIBE (effet Pedal) est
selectionné: pilote l’effet U-VIBE
• Quand le commutateur [EX CTL] (pilo-
tage externe) de l’ampli Valvetronix est sur
la position ON: pilote la vitesse de l’effet de
modulation (CHORUS, FLANGER,
PHASER, TREMOLO, ROTARY)
Commutateur de pédale
• Active/coupe l’effet Pedal.
Quand l’effet est actif, la diode s’allume en
haut à gauche de la pédale.

9. Pédale de volume
Cette pédale permet de piloter le volume.
Tu peux choisir une parmi trois courbes de
réponse pour la pédale de volume. Pour en
savoir plus, lis “Choisir la courbe de la pédale
de volume” à la page 25.
Dans le cas d’un ampli Valvetronix, la pédale
de volume pilote le niveau du signal après
l’étage de gain de l’ampli. De cette façon,
seul le volume change et le niveau de gain
reste inchangé.

2. Prise VOX BUS SUB
Cette prise permet de brancher un deuxième
ampli Valvetronix ou un appareil compatible
VOX BUS au VC-12 afin de piloter simultané-
ment les deux éléments connectés.
Remarque: Vu que le dispositif branché à la
prise SUB ne peut pas transmettre de signal
de pilotage au VC-12, tu dois utiliser le VC-
12 pour piloter simultanément les deux
dispositifs connectés.

Utilisation du VC-12
Cette section t’explique comment
choisir les mémoires, piloter les
effets et utiliser l’accordeur du
pédalier.Tu apprendras aussi comment
travailler en mode manuel et transmettre les
mémoires de ton ampli Valvetronix au VC-12.
Mode de sélection de mémoire
Comme son nom l’indique, le mode de
sélection de mémoire (Channel Select) sert
au choix des mémoires.
Activer le mode de sélection de mémoire
En mode de sélection de mémoire, l’écran
BANK indique le numéro de la banque de
mémoires choisie.Si aucun numéro de
banque n’est affiché, procède comme suit

Choisir des mémoires
Une fois que le mode de sélection de mé-
moire est actif, tu peux choisir les mémoires.
Les amplificateurs Valvetronix proposent 32
mémoires (réparties dans 8 banques conte-
nant chacune 4 mémoires).
1.Choisis la banque voulue (1, 2, 3, 4, 1., 2.,
3., 4.) avec les commutateurs BANK UP/
DOWN.
Le numéro de la banque choisie clignote à
l’écran BANK.
2. Choisis la mémoire voulue avec les
commutateurs 1–4.
Le numéro de la mémoire en question
cesse de clignoter et la diode du commuta-
teur enfoncé s’allume.
Te voilà paré pour la sélection des mémoi-
res.
Pour choisir une autre mémoire de la
même banque, il est inutile de spécifier à
nouveau la banque.Imaginons par exem-
ple que tu aies choisi la mémoire 3-1 et
que tu veuilles passer à la mémoire 3-3.
Pour cela, il te suffit d’enfoncer le commu-
tateur 3 (si le mode de sélection de mé-
moire est toujours actif).
Mode d’activation/de coupure
d’effet
En mode d’activation/de coupure d’effet, les
commutateurs 1–4 permettent d’activer et de
couper individuellement les sections Pedal,
Modulation, Delay et Reverb. Ce mode permet
aussi de choisir des mémoires, comme nous le
verrons à la fin de cette section.
Sélectionner le mode d’activation/de
coupure d’effet
En mode d’activation/de coupure d’effet,
l’écran BANK indique et la diode du
commutateur CHANNEL–FX ON/OFF est
allumée.Le cas échéant, sélectionne le
mode d’activation/de coupure d’effet en

banque, le mode de sélection de mémoire
est actif. Enfonce le commutateur CHAN-
NEL–FX ON/OFF pour choisir le mode
d’activation/de coupure d’effet.
•Si l’écran BANK indique , ou le nom
d’une note, la fonction Tuner (accordeur)
est active. Enfonce le commutateur TU-
NER pour couper cette fonction et retour-
ner au mode précédent. Si l’écran BANK
indique , le mode d’activation/de
coupure d’effet est actif.Si un numéro de
banque est présent sur cet affichage, tu es
en mode de sélection de mémoire.En-
fonce le commutateur CHANNEL–FX ON/
OFF pour passer en mode d’activation/de
coupure d’effet.
•L’écran BANK clignote lorsque tu changes
de banque sans choisir une mémoire.
Enfonce le commutateur CHANNEL–FX
ON/OFF pour revenir au mode précédent.
•Si l’écran BANK indique , ton ampli
Valvetronix est en mode manuel. Dans ce
cas, tu dois annuler ce mode sur l’ampli
avant de continuer.
Activer/couper les effets
Une fois en mode d’activation/de coupure
d’effet, tu peux activer/couper les sections
d’effets individuelles (Pedal, Modulation,
Delay et Reverb) avec les commutateurs 1–4.
Les diodes 1–4 indiquent si les sections
d’effets sont actives ou non.
Choisir des mémoires en mode
d’activation/de coupure d’effet
Cette section te montre comment sélection-
ner des mémoires en mode d’activation/de
coupure d’effet.
1. Choisis la banque voulue (1, 2, 3, 4, 1.,
2., 3., 4.) avec les commutateurs BANK
UP/DOWN.
