SECOND EDITION ( February 1986)
This
manual applies to OPTIMOD-TV Model 8182A with Serial Numbers of 780,000
or
above. It is not directly applicable to Model 8182A's with Serial Numbers below
780,000 due to a change in the wiring of Accessory Port # 1 that occurred starting
with
this Serial Number. It
is
not at
all applicable
to
the previous OPTIMOD-TV
Model
8180A
due
to
significant
changes
made
to
incorporate
the
Loudness
Controller circuitry and the Hilbert- Transform Clipper.
This
Manual
also
incorporates
minor
changes
and
corrections
to
the First
Edition
(November 1983) of the 8182A OPTIMOD-TV Manual.
In
addition,
this
Manual has been revised
to
explain the relationship
between the
8182A
and
the other parts of the Orban BTSC Television Stereo system, including
the
8182A/SG
Stereo
Generator,
the
8182A/SAP
Separate
Audio
Program
Generator,
and
the
8182A/PRO (previously
called " ACC- 20")
Professional
Channel
Generator ( which
plugs
into
the
8182A/SG
mainframe).
Separate
manuals
are
provided with all of these products.
Note in particular that integrated setup instructions for OPTIMOD-TV Model 8182A
and
the Orban 8182A/SG are provided in the manual for the Stereo Generator, not
in
this
Manual. If you are installing the 8182A and the 8182A/SG, the instructions
provided in Part 4 of this Manual ( which are
more general) should be ignored, and
the
instructions
in
Part
4 of
the
8182A/SG
Manual
should
be
followed
instead.
If
OPTIMOD-TV
is
installed
in
the " split" ( sometimes
called " dual- chassis")
configuration
using
a Model
8182A/ST
Accessory
Chassis,
please
refer
to
the
separate
manual
supplied
with
that
unit,
which
carries
basic
service
information.
Setup
instructions
for
the
8182A/ST
are
found
in
Part 4 of
this
8182A
Manual,
and
also
in
Part 4 of
the
8182A/SG
Manual.
This
8182A
Manual
is
frequently
referenced
in the manual for the Accessory Chassis and should be at hand during
installation and setup procedures.
