THIRD EDITION (January
1990)
This manual
applies to
OPTIMOD-TV
Model
8182A having
Serial Numbers
of 780,000
or above. It is
not
directly 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 and
Second
Editions
(November
1983;
February
1986)
of the 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
8185A
Stereo Generator,
the 8182A/SAP Separate Audio Program
Generator, and
the 8185A/PRO
(previously called "ACC-020") Professional
Channel Generator (which
plugs into
the
8185A
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 8185A are provided
in the
manual for
the Stereo Generator
,
not in
this manual. If you are installing the 8182A and the 8185A, the instructions provided
in Part 4 of this
Manual (which are more general) should
be
ignored, and the
instructions in
Section
2
of the
8185A 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
Section
2
of the
8185A Manual.
The
8182A Manual is frequently
referenced in the
manual
for
the
Accessory Chassis
and
should
be at hand
during installation and setup
procedures.
