Transient Modules 2M Manual

2M DIY kit build manual - Version 2.0
Hello!
This guide is for building the 2M module from Transient Modules.
It is good to have basic soldering skills and to be able to identify electronic components
before starting this kit. In case you're an experienced DIYer, please read all the steps
thoroughly before starting as some of them are not so obvious.
The 2M kit consists of two boards and all the parts comes in only two bags separated.
See the parts list below to identify each one of them easily before start building:

1. Let's begin with the back PCB. Start by
emptying the bag into a bowl or container.
This makes it much easier to pick parts as
you need them and you’re a lot less likely
to lose anything.
2. Solder the resistors labelled as 100K,
there are 13 of them.
Colour code: brown, black, black, orange,
brown.
3. Solder the two 1K resistors.
Colour code: brown, black, black, brown,
brown.
4. Solder the two 22pF capacitors (labelled
221).
5. Solder the two 100nF capacitors
(labelled 104).
6. Solder the two 47uF electrolytic
capacitors labelled 47uF.
NOTE! Orientation is vital. The longer lead on the
part should be positioned in the pad marked with
the plus/positive symbol.
7. Solder the two ferrite beads.
8. Solder the two 1N4007 diodes.
NOTE! Orientation is vital. The gray ring on the
diode must match the silkscreen.

9. Next solder the power header.
10. Place the 10 pin female header and
solder it ensuring it is 90º to the PCB.
11. Solder the two IC Sockets. !"#$%&'($

NOTE! You will need to bend the pins on the IC
inwards slightly so they are at 90 degrees to the
body of the IC. They will come slightly splayed out.
13. Front PCB now. Empty the bag of
potentiometers, jacks and nuts into a bowl
or container.
14. Some users asked for different types of
normalization between the mixers. There
are 3 possible configurations depending on
how the jumper pads are soldered:
1. No normalization. The two mixers are
independent.

2. When no cable is connected at the
output jack of the mixer on the left, its
output is summed to the inputs of the mixer
on the right. This normalization may be
useful if you want to mix 6 drum sounds to
one output. Note that the normalization is
made after the output potentiometer, so
there is a 'submix' control between the two
mixers.
3. The inputs of the mixer on the left are
normalled to the inputs of the mixer on the
right. This setting is useful when the mixer
is used for obtaining a L/R signal. This way
is possible to patch 3 mono signals and
obtain a (even panned) L/R signal at the
output.
Example of how must look the smd jumper
soldered pads. (Normalization 3 on the image)
15. Solder the 10 pin female header
ensuring it's 90º to the PCB.
NOTE! This part is placed at the bottom of the PCB
and soldered from the top, as shown on the image.
16. Next, place the 2x 100KB
potentiometers (labelled B104) and the 6x
100KA potentiometers (labelled A104) into
their position but DO NOT SOLDER yet.
Make sure they're 90º to the PCB and fully
inserted.

17. Screw the 11mm spacer (the one
which is slightly bigger) using one M3 black
screw as shown.
18. Place the eight jacks into their position
but DO NOT SOLDER yet.
19. Use your hands to screw the 10mm
spacer to the panel using the hexagonal
M2 screw (the one which is slightly tiny).
20. Place the front panel moving a little the
parts if necessary.
21. The spacer in the panel must match
the hole in the PCB. Join both using the
phillips M2 screw.
22. Place the 8 jack nuts and make sure
that the 2 nuts in the bottom are centered
with the silkscreen in the panel.
23. Now you can solder all the
potentiometers and jack sockets.

24. Join the front PCB and the back PCB
using the pin headers and ensuring the
3mm hole match the spacer. Screw both
boards with the last M3 black screw.
25. Connect the ribbon cable. The red
stripe on the cable must line up with the
white line on the module’s power
connector.

Check that all the inputs and both outputs
are working correctly, as well as the
normalization between the mixers in case
you did it.
