Introduction
Congratulations on buying the Fusebox synthesiser. Fusebox is part of the Analogue
Solutions range of analogue music equipment. Fusebox is a precision electronic
musical instrument. It combines all the often needed music electronic circuitry to make
a powerful music synthesiser in one compact module.
No compromise has been made with the construction of Fusebox. Cheaper options
in parts have not been used
• Full rugged steel/aluminium case - no plastic mouldings
• Good quality smooth, metal potentiometers, fully sealed against dust
• Good quality knobs with spun aluminium caps
• High grade double sided circuit board
• High Quality 16bit DAC for MIDI-CV conversion
• Stable MIDI to CV
• Stable analogue oscillators
• Designed, built, tested and assembled in the UK
• True retro analogue voice and modulation circuits to give an authentic retro
sound - no DSP.
WHY DO I NEED THIS SYNTH? WHAT’S SO SPECIAL?
Fusebox is a compact true analogue mono synth in a neat, smart, small package.
When we say ‘real analogue’ we mean that the entire audio path and all modulation
is entirely analogue, using circuits based on awesome sounding vintage 1970s
designs. Their circuits are not locked down by CPUs. Controls are not quantised and
read by CPUs. With the exception of the MIDI to CV circuit, which by its nature must
have a digital element, and the control sections of the sequencer (which even in
vintage sequencers is digital), Fusebox really is analogue and the sound benefit is
immediately apparent!
We get many good comments about how good Analogue Solutions products sound.
How wonderful, warm and full of character they are.
The synth has been designed by Tom Carpenter, a musician and a big fan of
electronic music. He knows how to program a synth and what should be expected. It
was not designed by an engineer or steered by committee or men in suits. So, the
modulation choices and range of sounds they produced have all been carefully thought
out and quickly give you those sounds you want: huge bass, synth leads, percussion,
effects, modular style sounds.

Analogue Solutions | FUSEBOX | Manual
FUSEBOX CAN BE AS COMPLEX OR AS SIMPLE AS YOU
WANT IT TO BE
We have given this synth a large and diverse number of controls, that along side the
patch sockets, will give even the best and experienced synthesist endless possibilities.
But hopefully we have presented the controls in a user friendly and familiar
monosynth layout that, together with this manual and other resources, enable even the
new guy to get great sounds.

Mounting Options
Fusebox can be orientated and configured in several ways;
VERTICAL (TALL)
As standard, it comes as a vertical desktop unit just like Telemark.
HORIZONTAL (FLAT)
It is possible to reconfigure it so that it is a flat table top unit, like its cousin Leipzig-S
is. This requires some minor screwdriver work. Essentially remove the 5 front panel
black screws, rotate the front panel 180 degrees, then re-screw.
RACKED
Remove the wood sides and fit optional rack ear brackets, and rack mount the whole
assembly. 7U height.!

Safety Instructions
PLEASE READ CAREFULLY BEFORE USING:
• Only use the correct power adaptor - 230V for UK/EU (115V for N.America).
• Never handle the adaptor with wet hands.
• Never excessively bend the adaptor cable or get it trapped or place heavy
objects on it. If the adaptor cable becomes damaged, replace the adaptor.
• Ensure the unit is disconnected from the mains before moving or cleaning.
• Always disconnect the unit from the mains if there is lightning in your area.
• Ensure the unit is on a stable surface, and never place heavy objects on top of
it.
• Never allow young children, hippies or animals to operate the unit or adaptor.
• Do not use excessive force when using the controls or inserting cables to the
connectors.
• The unit should not be operated in the rain, near water, or at a foam party, and
should not be exposed to moisture.
• If the unit is brought from a cold environment to a warm one, the unit should be
left to reach the ambient temperature.
• Keep away from heat sources, such as radiators, ovens, heaters etc.
• Never allow it to get wet. Do not operate it near water, like pools, sinks,
bathrooms etc. Oh, we covered that already.
• Do not place beverages on or near it.
• Never open the case or attempt to make repairs. Refer any servicing to qualified
service personnel.
PREVENTING DAMAGE TO OTHER CONNECTED DEVICES
Fusebox has a very high dynamic range. It is capable of produce loud signals of
very high and sub-sonic frequencies that could blow inadequate speakers if played too
loud. It is recommended that input levels to external equipment (mixers, amp's etc.) are
kept low when first connected, and then slowly increased to a useable level.
MAINTENANCE INSTRUCTIONS
Any cleaning of the Fusebox case should be done with a clean lint-free cloth. "
DO NOT USE SOLVENTS OR CLEANERS, as this will deteriorate the exterior
appearance of the equipment. Do not use a car wash or jet wash to clean this synth.
PLACE
Place Fusebox soundly on a stable surface so it cannot fall off or over, causing it or
yourself injury.
POWER
The unit needs a 12 to 15V AC supply, minimum 500mA. DC Power supplies will not
work.
Fusebox - 30 Oct 2017 | Page !11

Analogue Solutions | FUSEBOX | Manual
Getting Started
POWER
Fusebox comes with a power supply. It uses a power supply with an AC output.
Plug the power lead into the rear of Fusebox.
MIDI
Fusebox has;
MIDI In for sequencing from DAW or playing via MIDI keys.
MIDI Thru outputs a copy of what comes into the MIDI In socket.
MIDI Out outputs a copy of what comes into the MIDI In socket. If the Arpeggiator
is on, then these notes will be played out this socket.
Example set up;
Connect MIDI Out from your computer DAW MIDI interface or MIDI keyboard to
MIDI In of Fusebox.
Optionally connect MIDI Thru from Fusebox to the MIDI In of another device.

Analogue Solutions | FUSEBOX | Manual
Initial Tuning
Once the MIDI and audio connections have been made it may be necessary to tune
in the VCOs to the rest of your music set-up. Allow a five minute warm up time as these
are true analogue VCOs – that’s why they sound so great!
There are many controls on this synth that can affect one or all of the VCOs!
First set up the controls of Fusebox to make a simple sound.
Set Master Tune to the centre.
Ensure the Patternator pitch control is set to zero.
Ensure the Interval Generator is disabled.
Ensure the Arpeggiator is off.
Note, that patch leads plugged into the VCOs might also affect pitch.
Set VCO1 Octave to off.
Set Sync to off.
Set Xmod to off.
Set Low to off.
Set Free to off.
Turn VCO2 and VCO3 to zero volume so you can only hear VCO1.
Play, say, middle C on the keyboard. Using a digital keyboard as a reference, adjust
the tuning of VCO1 until it plays in tune with your reference.
Turn up VCO2 so both VCOs can be heard. Using the tune control of VCO2, tune it
to VCO1.
Finally, turn up VCO3 so all VCOs can be heard. You may prefer to turn down VCO2
at this point so you just hear VCOs 1 and 3. Using the tune control of VCO3, tune it to
VCO1.
This synth is truly analogue - and uses an old VCO circuit design to give it its great
sound. DON’T expect DCO or DSP style precision pitch.
The pitch will be in tune but have subtle shifts across the octaves due to their
vintage design. This is in part what adds to the character and warmth of the sound.
That’s the whole point!

Circuits in Detail
Here follows details on the sockets and controls, with brief simplified explanations of
what the circuits do. We have not gone into technical details on how or exactly what
each circuit does but tried to explain each control's function and effect.
This synth has been designed to be simple and intuitive to use, just like the original
analogue synth’s of the 70s and 80s. There are no multi-layered menus to work
through.
Anyone who has used synthesisers before should be familiar with the terms used
and therefore be able to predict their behaviour and how they affect the sound. The
best way to learn how to use Fusebox is to go straight ahead and play with it. Reading
of this manual may only be necessary for finer operational detail.
There are many many web resources and books available if you need actual tuition
or explanation of how functions like LFO, ADSR, etc work or can be used.

VCO - Voltage Controlled Oscillators
Fusebox has three analogue VCOs. These produce the raw audio sound source for
later processing.
VCO3 can be detached from MIDI note and be used independently as a voltage
controlled LFO - for modulation duties.
Fusebox - 30 Oct 2017 | Page !15

Analogue Solutions | FUSEBOX | Manual
VCO1
DETUNE
Use this control to alter the pitch in small amounts to detune relative to the other
oscillators.
PITCH
This control is used to attenuate any modulation signal that you patch into the socket
below.
Examples of modulation signals are outputs from the LFO or EG, or from an external
modular system (eg Eurorack). An audio signal can also be used, such as the audio
outputs from the other oscillators.
PW - Pulse Width
This control allows you to manually change the pulse width of the Square waveform.
PWM - Pulse Width Modulation
Use this control to alter the amount external modulation that you patch into the
socket below.
Examples of modulation signals are outputs from the LFO or EG, or from an external
modular system (eg Eurorack).
Square / Sawtooth
There are separate jack socket audio outputs from the two VCO waveforms.
These can be patched to other circuits, for example, used to modulate the pitch of
another oscillator.
OCT - Octave
Click right to transpose the pitch up one octave.
XMOD - Cross Modulation
Fusebox - 30 Oct 2017 | Page !16

Analogue Solutions | FUSEBOX | Manual
Click right to turn XMOD on. This routes Square wave audio out from VCO2 to
VCO1 pitch. Used for amazing effects!
VCO2
DETUNE
Use this control to alter the pitch in small amounts to detune relative to the other
oscillators.
PITCH
This control is used to attenuate any modulation signal that you patch into the socket
below.

Square / Sawtooth
There are separate jack socket audio outputs from the two VCO waveforms.
These can be patched to other circuits, for example, used to modulate the pitch of
another oscillator.
WIDE TUNE
Click right to dramatically increase the range of the DETUNE control. You can take
the frequency right down to LFO speeds, and right up to much higher pitches.
Fusebox - 30 Oct 2017 | Page !17

Analogue Solutions | FUSEBOX | Manual
Ideal for using VCO2 as an LFO, or for extreme modulations effects.
SYNC
Click right to turn SYNC on. This causes VCO1 and VCO2 to become synchronised
(in pitch). Use for Sync effects.
VCO3 (VCLFO)
DETUNE
Use this control to alter the pitch in small amounts to detune relative to the other
oscillators.
PITCH
This control is used to attenuate any modulation signal that you patch into the socket
below.
Examples of modulation signals are outputs from the LFO or EG, or from an external

modular system (eg Eurorack).
Square / Sawtooth / Triangle
There are separate jack socket audio outputs from the two VCO waveforms.
These can be patched to other circuits, for example, used to modulate the pitch of
another oscillator.

WIDE TUNE
Click right to dramatically increase the range of the DETUNE control. You can take
the frequency right down to LFO speeds, and right up to much higher pitches.
Ideal for using VCO3 as an LFO, or for extreme modulations effects.
MIDI PITCH
Click left to turn off / disconnect VCO3 pitch control from MIDI.
A typical use for this is for VCO3 to be free running and independent from MIDI
pitch, enabling it to be used as a modulator (LFO or otherwise).
GENERAL VCO CONTROLS (APPLY TO ALL 3)
MASTER TUNE
Used to alter the pitch of all three VCOs.
GLOBAL PITCH
This control alters the level of any modulation signal patched into the adjacent
socket. The modulation signal will affect all three VCOs.
For example, to get equal vibrato playing on all three VCOs, patch the sine wave
from the LFO into here.

LFO - Low Frequency Oscillator
In addition to being able to use VCO2 or VCO3 as modulators, there is a dedicated
analogue LFO.
It has two 2 Sine wave jack socket outputs and two Square wave jack socket
outputs.
SPEED
This control alters the LFO speed / frequency.
CUT-OFF
This sets the amount of Sine wave LFO signal that will modulate the Filter
Frequency Cut-Off (sounds a little like wah-wah!).
PWM
This sets the amount of Sine wave LFO signal that will modulate all three VCOs’
Square wave pulse width.
