                                    OPTIMOD-AM is a powerful system for obtaining the best
possible quality from the AM broadcast medium. This medium
includes the station's transmission system plus the
listener's receiver, listening environment, and
,	The OPTIMOD-AM 9100A system is designed for universal
application in domestic

;	and international LW, MW, and SW services. While
OPTIMOD-AM is ordinarily

shipped with a 12kHz output bandwidth to comply with FCC
(U.S.A.) specifications for the U.S. MW broadcast service,
an optional 5kHz bandwidth-limiting filter card may be
plugged into the system to conform its output spectrum to
EBU and other !	standards, or to resolve unusual adjacent
channel interference problems.

1	OPTIMOD-AM is available in two versions: a stereo version
(9100A/2) which

|	processes by the "sum-and-difference" method to yield
ready compatibility with any

proposed AM Stereo system, and a mono version (910GA/1)
which can be field-converted to stereo by plugging in three
additional circuit cards. No "Stereo I	Accessory Chassis" is

By performing the following functions, the OPTIMOD-AM system
delivers a louder, i	cleaner, brighter, FM-Iike sound whose
open, fatigue-free quality attracts listeners

I	and holds them:
1.	It rides gain over a range of as much as 25d8,
compressing dynamic range and compensating for gain-riding
errors on the part of operators and for gain inconsistencies
amongst automation tapes. The amount of dynamic range
reduction is adjustable.

2.	It increases the density and loudness of the program
material by means of multiband limiting and multiband
distortion-cancelled clipping, achieving remarkable
increases in loudness and definition without audible
3.	It compensates for the high- and low-frequency rolloffs
of typical AM receivers by means of a statistically-derived
fully-adjustable program equalizer. Up to 22dB of HF boost
can be produced above 6kHz. This extreme equalization can be
readily handled by the processing without the side-effects
encountered in conventional processors.

4.	It reliably controls peak levels to prevent overmodulation.

5.	It improves the consistency of the station's equalization
texture by means of multiband limiting.

6.	It compensates for inaccuracies in the pulse response of
transmitters and antenna systems by means of a powerful
transmitter equalizer with four adjustable correction
parameters. Four complete sets of adjustments may be preset
and recalled as needed by remote control.

7.	It controls the bandwidth of the transmitter emissions as
necessary to meet the specifications of government
authorities, regardless of program material or equalization

This Manual is organized into two major sections. The first
contains information on how to plan your installation, how
OPTIMOD-AM interfaces with other station equipment, how to
set up and adjust OPTIMOD-AM, how to do a Proof of
Performance, and brief comments on routine maintenance. You
should read Parts 1,

2, and 3 before attempting to install OPTIMOD-AM.

The second section contains Appendices which provide useful
information that you may need at some time during the life
of OPTIMOD-AM. This is primarily reference material; you do
not need to digest it to install, set up, or operate your unit.

There is no Index, so the TABLE OF CONTENTS should be used
to help you find the information you want. The TABLE OF
CONTENTS provides an overview of the organization of the
manual, and lists in some detail the topics discussed.
