When
replacing the DOLBY NR
lC PA3012
in
3-head
decks:
1.
As
a rule, replace
ICs with only
ICs
of
the
same rank
within each channel
(right
or left).
2. If an IC
of the same
rank is not
available, the
IC of one rank higher
or lower
(see
table
1
below) can
be used instead. However,
after re-
placement,
the ICs
on the recording
side
and
the
playback
side must not
differ by more
than
one
rank.
3.
The
colors in table
1
refer
to the
color marking
on the
top surface
of the
IC
package
(see
fig.1).

Example:

In
this
example,
the
