1. Remove all knob
and fader caps
CROSSFADER REPLACEMENT
To replace the crossfader remove all power
and signal cables from the mixer and, follow
these steps:
1. Remove all knob and fader caps. There
are 38 pieces in all. You do not have to do
anything with the buttons or switches.
2. Remove the 12 faceplate screws using a
small Phillips screwdriver.
3. Remove the faceplate by pulling straight
up. This will expose the sub-chassis and
give you access to the crossfader.
4. The crossfader is connected to the mixer
using a standard molex-style connector.
Use care when separating the connector
from the installed crossfader.
5. If you are installing a crossfader with
adjustable parameters, it makes sense to
make all adjustments needed BEFORE
reinstalling the crossfader and putting the
mixer back together.
(PLEASE NOTE – When replacing the
crossfader, the performance of the crossfader
curve controls may change. Please take a
moment to learn if the behavior of the curve
controls has changed.)
