POWER SUPPLY
D100PRE is shipped with multi tap IEC socket, and input voltage can be choose
between 100-120-230 and 240VAC.
You must need a flat screwdriver to open IEC socked and rotate internal selector.
It’s very important you do this with power cord NOT CONNECTED to IEC socket,
and with D100PRE rack totally closed, since there’s not need to open the case.
If you’re not sure of what you’re doing, please bring it to a qualified person, you’re
messing with potentially lethal voltages, who can hurt you and D100PRE.

PREMISE
D100PRE is based and it’s the natural evolution of our flagship amplifier, Duality100.
With the idea of 1:1 porting of preamplifier section into a standard 2U rack case, we
took the time to develop some new ideas and concepts, by keeping Duality series
signature sound intact and unmodified.
As any guitar preamplifier in the world, also D100PRE is needed of a power amplifier,
so take this into account.
We developed D100PRE using D100 power amplifier section, to be 100% faithful to
the legacy, but of course it can be used with any PA available, with any sort of tubes,
or solid state too.
VERSIONS
D100PRE con be ordered in “Standard” and “RS (Red Stealth) version, as our Duality
series.
• Standard version is the original Duality sound, EL34 based and optimized for
this type of tubes.
• RS (Red Stealth) version is a modified version of the original sound, featuring
an overall higher saturation level and a tad brighter and aggressive sound,
only in dirty channels. Clean channel still remains the same on both version.
This mod was specifically designed to be run with 6L6s tubes.

SOUND DESCRIPTION
•
CH1 (Clean channel)
is something between and old ‘50s Fender and late ʼ60
Marshall SL Plexi. Sparkly, rich, 3D clean sound, something hard to find in
today’s modern multichannel amps. It can crunch with aggressive pickups but
it’s almost clean with any guitar below gain set at 4. Tonestack is way more
effective than the vintage ‘50/ʼ60 mono channel amplifiers, you can obtain
quite a lot different sounds from this channel. Bright switch also adds some
flexibility to it.
•
CH2 (VINTAGE):
Vintage channel is where you probably want to spend most
of your time and also our signature sound. Gain can be set from a crunchy
Marshall-esque type tone (think of early AC/DC) to ‘80s VH. Not a super huge
gain quantity and no over-saturated gain in the low end. With guitar’s volume
control you can still have a very good clean sound, even with gain dimed.
With “LEAD” mode engaged you are in late hard rock ‘80s territory. Quite a
lot of gain available now, consistent bass response, dynamics is always at
maximum. Eq is shared with MODERN channel and itʼs way more effective
than your usual eq and probably a bit different.
•
CH3 (MODERN):
The Modern channel starts where the Vintage channel ends
but with a little more gain and bass frequencies on top. This is a lot tighter,
gainy, compressed and saturated sounds than the previous channel. It has
right amount of gain to play solos even without using “LEAD” mode. Engaging
“LEAD” mode you’ll have a huge quantity of gain, you can be ready for any
hard rock / classic metal tones.!
IMPORTANT NOTE:
while VINTAGE and MODERN channel shares same eq controls
they are two completely separated channels. This allows us to have two different
flavors of same sound. Pure magic.
