Layout: Designators for some resistors use a C prefix
Somehow, the wrong designator has been used for some resistors on the
top overlay.
Resistors R167-1R167-6 and resistors R168-1>R168-6
are labeled in silkscreen as C167 and C168 for all channels.
This is strange especially as the altium project clearly shows that
these components are indeed resistors NOT
capacitors
The PCB has designators C167 and C168 already assigned to two capacitors, in a different footprint at different locations (bottom layer).
If the manufacturer uses pick and place machines (and NOT designators)
to place components then this should not cause any functional problem.
Nonetheless, on reception of prototypes, it should be visually checked
that correct resistor values have been mounted on these pads.
This issue, though confusing, is not urgent and change can be
implemented if ever a new version of the board is proposed.
