A most popular range available
with cermet or co-moulded
resistance elements. This choice
means that components offer
excellent electrical and thermal
stablity, reliability, low noise and
long life which makes them
highly suitable for the majority
of professional applications.
The MC1 Series is used in the
Tornado Project and is the
standard single turn general
purpose panel control used for
most military applications in
the UK and Europe.
