Section 4: Resolving some common issues.
Below are some common issues that can appear on QuickQ consoles and how to solve
these, including replacing faders, encoders, and resolving issues with LEDs.
Replacing faders:
Faders can naturally wear down with use and may end
up needing replacement if noise is being experienced,
or they feel scratchy, or unusually loose. To replace
faders, first remove the relevant PCB from the console,
as per the instructions in section 3.
Start by completely de-soldering the 8 solder joints for
the fader, as highlighted in the image to the right. The
holes must be completely free of solder to allow the
fader to be removed. Once removed, place the new
fader into the holes and solder the connections. We
recommend using high-quality lead-free solder.
Fader part number: 308-016-02
Replacing encoders:
It is common for encoders to wear with use. As
mentioned in section 2, when testing encoders, you
should see positive values only when rotating clockwise
and negative values when rotating anti-clockwise. If
mixed values are experienced in one or both directions,
the encoder will need replacing. To replace an encoder,
first remove the relevant PCB from the console, as per
the instructions in section 3.
Start by completely de-soldering the 5 solder joints for
the encoder, as highlighted in the image to the left. The
holes must be completely free of solder to allow the
fader to be removed. Once removed, place the new
encoder into the holes and solder the connections.
Encoder part number: 417-003
