It's

hard

to

beat

analog

synths

for

fat,

punchy

bass

lines.

And

for

discovering

new

sounds,

nothing

comes

close

to

real

knobs

operating

in

real

time.

The

FatMan

has

all

of

the

features

that

give

analog

it's

warm,

full

tone

in

a

MIDI

controlled

package.

The

classic

normalization

scheme

of

twin

VCO/

VCFNCA

and

Dual

Transient

Generators

is

brought

up

to

date

with

the

inclusion

of

Velocity

CV

not

available

on

pre-MIDI

synths.

FatMan

learns

from

the

past

by

including

features

that

were

eccentricities

of

classic

synths

such

as

a

unique

“punch"

switch

that

adds

a

subtle

but

useful

fifth

segment

to

the

standard

ADSR

response.

ASSEMBLING

THE

FatMan

MIDI

Synth

Before

beginning

assembly,

go

through

the

manual.

Look

at

the

drawings.

Feel

the

parts.

You're

naturally

eager

to

plunge

right

in,

but

take

a

few

deep

breaths

first.

Check

the

parts

supplied

against

the

packing

list

on

the

last

page

of

this

manual.

In

some

cases,

notes

packed

with

the

parts

will

be

used

to

call

your

attention

to

special

situations.

These

notes

may

be

in

the

"MISSING

PARTS"

postcard.

If

parts

are

missing

please

notify

PAiA

at

phn

405.340.6300,

fax

340.6378,

or

[email protected]

.

Notice

that

each

step

in

the

manual

is

marked

with

a

checkoff

box

like

this:

Checking

off

each

step

as

you

do

it

may

seem

silly

and

ritualistic,

but

it

greatly

decreases

the

chance

of

omitting

a

step

and

also

provides

some

gratification

and

reward

as

each

step

is

completed.

Numbered

assembly.

THE

CIRCUIT

BOARD

The

FatMan

is

built

on

a

single-sided

circuit

board.

The

solder

side

of

the

board

is

soldered

masked

with

a

conformal

coating

and

conductors

are

tin-lead

plated

for

ease

of

soldering

and

assembly.

No

cleaning

of

the

circuit

board

or

other

special

preparation

is

necessary

before

beginning assembiy.

TOOLS

You'll

need

a

minimum

of

tools

to

assemble

the

kit

-

a

smail

pair

of

diagonal

wire

cutters

and

pliers,

screwdriver,

sharp

knife,

ruler,

soldering

iron

and

solder.

Modern

electronic

components

are

small

(in

case

you

hadn't

noticed)

and

values

marked

on

the

part

are

often

difficult

to

see.

Another

handy

tool

for

your

bench

will

be

a

good

magnifying

glass.

Also

use

the

magnifier

to

examine

each

solder

joint

as

it

is

made

to

make

sure

that

it

doesn’t

have

any

of

the

problems

described

in

the

SOLDERING

section

which

follows.

CAUTION-SMALL

WIRE

Use

particular

care

when

stripping

the

#

26

insulated

wire

supplied

for

panel

witing.

A

low-cost

wire

stripping

tool

available

from

any

electronics

supply

store

is

a

good

investment

and

can

be

set

so

that

only

the

insulation

is

stripped

away

without

nicking

and

weakening

the

wire

strands.

When

instructed

to

“tin”

the

end

of

a

wire,

make

sure

the

solder

wicks

into

the

entire

length

of

the

exposed

wire

strands

-

don't

just

put

a

blob

of

solder

on

the

end.

SOLDERING

Select

a

soldering

iron

with

a

small

tip

and

a

power

rating

not

more

than

35

watts.

Soldering

guns

are

completely

unacceptable

for

assembling

solid

state

equipment

because

the

large

magnetic

field

they

generate

can

damage

components.

Use

only

rosin

core

solder

(acid

core

solder

is

for

plumbing,

not

electronics

work).

A

proper

solder

joint

has

just

enough

solder

to

cover

the

soldering

pad

and

about

1/16-inch

of

lead

passing

through

it.

There

are

two

improper

connections

to

beware

of:

Using

too

littie

solder

will

sometimes

result

in

a

connection

which

appears

to

be

soldered

when

actually

there

is

a

layer

of

flux

insulating

the

component

lead

from

the

solder

bead.

This

situation

can

be

cured

by

reheating

the

joint

and

applying

more

solder.

If

too

much

solder

ts

used

on

a

joint

there

is

the

danger

that

a

conducting

bridge

of

excess

solder

will

flow

between

adjacent

circuit

board

conductors

forming

a

short

circuit.

Accidental

bridges

can

be

cleaned

off

by

holding

the

board

upside

down

and

flowing

the

excess

solder

off

onto

a

clean,

hot

soldering

iron.

Use

care

when

mounting

all

components.

Never

force

a

component

into

place.
