Transient Modules u3A Manual

Transient Modules u3A DIY build manual - Version 1.1
Hello!
This guide is for building the u3A module from Transient Modules.
Even if you're an experienced DIYer, please read ALL the steps thoroughly
before starting, as some of them are crucial and others not so obvious.
The u3A kit consists of two boards and all the parts comes in one bag.
See the lists below to identify each one of them easily before start building.

;;"#Place the 6x jack nuts and make
sure that the 3 nuts in the bottom are
centered with the silkscreen in the panel.
Also make sure the 3 LEDs are
positioned through the holes in the panel.
Now you can solder all the jack
sockets, potentiometers and leds.
;I"#Join the front PCB and the back PCB
using the pin headers and ensuring the
3mm hole match the spacer. Screw both

;O"#Connect the ribbon cable. The red
stripe on the cable must line up with the
white line on the module’s power
connector. W/9"""

No calibration is needed for this module.
Check that all the inputs, outputs, offsets
and mixings work correctly!
