1. Thank you
for choosing this rhythm computer.
It’s a unique clone for sound and feeling of the famous Minipops7
TM
as used throughout
several parts of world renown music by Jean Michelle Jarre.
The MiniP7 has been designed to mimic the ‘spirit’ of the Minipops7
TM
as good as
possible.
Please read the assembly and operating instructions carefully to ensure the unit’s fullest
performance.

4.1. Assembly of TH Components and Spacers
See Technical Spec for enlarged view.
4.1.1. Population of the LEDs
Mount the LEDs with the pin enlargement just above the PCB. Long Pin is Anode and should be the upper
pin. The shortest pin is Cathode and should connect to the SOT23 Transistor.

4.1.5. Population of the Jacks
Although this can be done at this time, it may
be better to assemble the jacks after the PCB
has been put on the front panel.
n the latter case be careful not to scratch the
front panel. The jacks will be at their correct
height and the pins can be bent to solder
direct to the PCB at the right vertical position.

4.1.7. Population of the Header
The boxed header has to be mounted
on the bottom side of PCB.
Pin 1 should be at the lower edge of the
board.

4.1.8. Mounting of the Spacers
Mount 6 spacers at their positions using an M2.5 x 6 mm bolt. No springs are foreseen. One can
always add a spring or put some lacquer to avoid unintentional loosening of the bolt.
