2M DIY kit build manual - Version 2.0
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.
