NOTE:
These
specific
application set-ups
are
intended
as
a
starting
point
for integra-
tion
of
the
Co-Operator
into
your
system. Actual
set-ups will
vary with experience
and
experimentation.
There
are also
many
other
production
applications
which by
their
nature
do
not lend themselves
to
a
chart-like
presentation
of
recommended
settings.
In these
applications,
experience
and
experimentation
are the best guides.
Audio Tape Recorder
Because
applications are
so
diversified,
each
with special
needs,
no
generalized
set-
tings
can be
recommended. Read
"More About Co-Operator Audio
Processing"
on
page
3-8.
The
table
on page
3-10 suggests
appropriate
pre-emphasis
for
various
recording
speeds.
STL
Protection
Assumes
that
only safety
and
high-frequency
limiting
are
wanted.
If
leveling
is
also
desired,
use
"Broadcast Transmission"
settings.

obtained
by
reducing bias voltage
on
