The CEM3379 is used in the A-106-6, A-107, A-109 and A-122 (new versions
only). The CEM3379 has exactly the same filter design as the CEM3389, only
the input impendance of some control inputs, the function of pin 16 and the
control scale of the panning output (not used in A-106-6, A-107 or A-122)
are different for both circuits. The filter design and sound are the same.
