4.3.2 Pin settings and labelling
Users can create custom labels for the: microphone/line
inputs, description of the music sources, and audio
output zones 1 and 2. These labels can be attached to
the mixer amplifier at position numbers 2, 4, and 6 (see
figure 2.2). Colored pins can also be inserted at various
positions around the dial controls to indicate the favorite
settings for a particular application.
The pins are engineered in such a way that they cannot
be taken out by hand. This is to prevent tampering. The
pins are intended to be inserted once, during installation
of the unit. The silver pins should be used to indicate
the preferred settings of the unit. The red pins can
optionally be used to indicate the maximum setting of a
knob.
If these settings have to be changed, use a pair of soft-
tipped pliers to carefully remove the pins. If you do not
have a pair of soft-tipped pliers, you can use ordinary
pliers instead, but first place some plastic tape on the
tips of the pliers to prevent damaging the front of the
unit.
To remove the clear plastic covers in front of the labels:
1 Carefully insert a small screwdriver into the cut-out
at the bottom of the plastic cover.
2 Gently lift the cover, and bend it in the middle. Take
care not to force the cover or the front panel.
To reattach the plastic covers with paper labels:
1 Insert the paper label into the holder at the front of
the unit.
2 Pick up the cover, and then bend it slightly in the
middle by hand.
3 Fit the cover into the slot at the front of the unit, and
then gently release the cover, making sure that the
paper label stays in place.
