1. Assembly (Skipping this can lead to troubles ! )
Ok, so we have your attention. These hints will help you to make this project success-
ful. Read them carefully.
1.1 Make sure you have the right tools:
•A good quality soldering iron (25-
40W) with a small tip.
•Wipe it often on a wet sponge or cloth, to keep it clean; then apply solder to the
tip, to give it a wet look. This is called ‘thinning’ and will protect the tip, and en-
ables you to make good connections. When solder rolls off the tip,
it needs cleaning.
•Thin raisin-core solder. Do not use
any flux or grease.
•A diagonal cutter to trim excess wires. To avoid injury
when cutting excess leads, hold the lead so they
cannot fly towards the eyes.
•Needle nose pliers, for bending leads, or to hold components in
place.
•Small blade and Phillips screwdrivers. A basic range is fine.
For some projects, a basic multi-meter is required, or
might be handy
1.2 Assembly Hints :
⇒Make sure the skill level matches your experience, to avoid disappointments.
⇒Follow the instructions carefully. Read and understand the entire step before you
perform each operation.
⇒Perform the assembly in the correct order as stated in this manual
⇒Position all parts on the PCB (Printed Circuit Board) as shown on the drawings.
⇒Values on the circuit diagram are subject to changes.
⇒Values in this assembly guide are correct*
⇒Use the check-boxes to mark your progress.
⇒Please read the included information on safety and customer service
* Typographical inaccuracies excluded. Always look for possible last minute manual
updates, indicated as ‘NOTE’ on a separate leaflet.

1.3 Soldering Hints :
Mount the component against the PCB surface and carefully solder the
leads
Make sure the solder joints are cone-shaped and shiny
Trim excess leads as close as possible to the solder joint
REMOVE THEM FROM THE TAPE
ONE AT A TIME !
AXIAL COMPONENTS ARE TAPED IN THE CORRECT
MOUNTING SEQUENCE !

Construction
The ideal equipment for disc-jockeys, jingles for free radios
or simply as an attention drawer. All sounds have been
realised by means of a programmed micro-processor. The
sounds generator has an output for direct connection of a
loudspeaker and a line output for connecting a mixing
panel or an amplifier.
The following effects can be called directly through push
buttons:
—Machine-gun (random number of shots with bullet impact).
—European siren.
—Phasor gun (STAR-WARS-like machine-gun).
—Racing-car engine (increase/decrease the number of r.p.m.).
—Car tire screech
—Explosion.
—Mortar shot followed by an explosion.
—Tune: "Wild charge tune".
—Tune: "Snake charmers tune".
—U.S.A. siren.

—Turn the potentiometer to its centre position.
—Connect a loudspeaker (8 ohm / 1Watt min.) between
the points LS.
—Connect a power supply (9VDC) or a 9V battery bet-
ween the points +V and -V.
—Pressing the different push buttons now causes the
respective effects to be produced.
FATTENTION: With some of the effects (e.g. sirens,
car engine) it's necessary to keep the push button
pressed. The speed of the effects can be changed
(optimized) by turning the potentiometer.
The OUT output allows you to extra amplify the
sounds or to connect them to a mixing panel. In this
case you possibly can disconnect the loudspeaker.
Thanks to the position of the push buttons and of
the potentiometer, this circuit can be built into a
plastic housing or the pcb be mounted behind a pa-
nel very easily.
