Installation
—
Most
Applications
Allow
about
20
minutes
for
installation.
If
you
will
be
using the
Co-Operator
to
protect
an
FM
transmitter,
STL,
or subcar-
rier
generator
use the
"Installation
—
FM
Transmitter,
STL,
Subcarrier
Generator
Protection"
instructions
on
page
2-9.
Ins
talla
tion consists
of unpacking and
inspecting the
Co-Operator,
optional
resetting
of
clipper-defeat
and
pre-emphasis jumpers,
mounting
the
Co-Operator
in
a
rack,
then
connecting audio
and
power.
1)
Unpack and
inspect.
If
obvious
physical
damage
is
noted, contact the
carrier
immediately
to
make
a
damage
claim.
If
you
should ever
have
to ship the
Co-Operator
(e.g.,
for
servicing),
it
is
best
to
ship
it
in the original
packing
materials since these
have been
carefully
designed
to protect
the
unit.
Therefore,
make
a
mental
note of
how
the unit
is
packed and
save
all
packing
materials.
Packed
with
the
Co-Operator
are:
1
Warranty
Certificate
1
Registration
Card
1
Operating
Manual
2)
Reposition clipper-defeat
and
pre-emphasis
jumpers.
(optional)
A
list
of
recommended
jumper
positions for various applications
begins
on
page
3-4.
If
you want
to
reposition these
jumpers,
you
will
need
to
remove
the top
cover
of
the
Co-Operator
to
access
the
main
circuit
board.
Remove
all
screws holding
the
cover
in place,
then
lift
it
off.
When
replacing the cover, replace
all
screws
snugly.
(Be
careful
not
to
strip
the
threads
by
fastening the
screws
too
tightly.)
a)
If
you want
to
enable
the
peak
clippers,
reposition
jumper
A
on
the
main
circuit
board
to
the
"OPERATE"
position (see Fig.
2-1).
The
Co-Operator
is
shipped with
this
jumper
in
the
"DEFEAT'
position.
In general, the
clippers
should only
be
activated
if
the device
being
driven has
an
absolute
peak overload
point
(a
broadcast
transmitter, for
example).
The
HF
LIMIT
buttons
must be
set to
OPERATE
for the
peak
clippers
to
be
active.
b)
If
you want
a pre-emphasized
output, reposition
jumpers
B
and
C
on
the
main
circuit
board
to
the
"PRE-EMPHASIZED"
position (see Fig.
2-1).
The
HF
LIMIT
PRE-EMPHASIS
switches
determine
the
pre-emphasis
curve
that will
be
used.
