WARNING!! This preamplifier uses potential lethal voltage, it must be inspected only by expert people! WARNING!! Before insert power cord inside D100PRE, check the voltage plate under IEC socket and be sure to match your country’s wall voltage.
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.
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.
TECHNICAL FEATURES FRONT PANEL: Top row (from left to right) • CHANNEL 1 (clean channel): Gain, Bass, Middle, Treble, Volume controls. • SOLO BOOST: Level (0 is unity gain), Bite (top end), Focus (bottom end) Bottom row (from left to right) •...

• BRIGHT: activates bright cap, different value for each channel; • SOLO: activates solo boost (it works in each channel); • BT: activation for internal Bluetooth receiver. Used for remote channel switching (to be developed; • STORE: store button, to save sound combinations inside D100PRE memory.

REAR PANEL (from left to right) • IEC SOCKET: connect your power cable here. • HT FUSE: (1A slo blow) high current fuse. Replace ONLY with same type. • MIDI IN & MIDI THRU: sockets for midi communications. Midi IN receive midi signal, Midi THRU left midi signal pass thru without modify original messages.
Switches for Ch1, 2 and 3 or Clean, Vintage and Modern channels. LEAD BOOST As its big brother Duality 100, D100PRE featured a tube based gain boost for CH2 and CH3. This boost basically adds a gain stage somewhere in the signal path by not afflicting your overall volume.

D100PRE, despite the full tube audio signal path, is equipped with digital memory and can save combinations (presets) of functions inside D100PRE. D100PRE is shipped on midi channel #1. You can’t change midi channel on the fly after bought it, but you can ask for a different midi channel at order time.

There’re two outputs on D100PRE’s back panel. Your “to go” output is the one named “+4dB output”, and it’s the direct output from last tube of D100PRE. It’s a full line level output signal, with enough headroom to drive any external line level effect processor or any power amplifier.

IEC SOCKET We wanted D100PRE to be a valid a choice for world travelling professional guitarists. Main IEC power socket has a special voltage selector, to easily change input voltage, from 100-120-230 to 240VAC, without opening rack case nor the use of a solder machine.
SAME type and try again to turn on again. If fuse continue to blown, turn off the amp and contact RedSeven Amplificaton. • D100PRE IS TURNING ON (RED LIGHT IS ON) BUT WITH NO SOUND Be sure you turned on you power amplifier;...
This amplifier runs at very high voltage that can lead to death. Any inexpert person should not even think of do anything inside this amplifier. RedSeven Amplification offer a standard two year fully warranty for any component (except wear subjects).
