1. INTRODUCTION
1.1. Crown Broadcast History
Crown Broadcast is a division of International Radio & Electronics Corporation located in Elkhart, Indiana.
Crown began as International Radio and Electronics Corporation in 1947. The founder's intent was to
provide high-quality audio equipment and transmitter products to the broadcasting industry.
In the following decades, the company evolved into a world-class supplier of professional audio equipment
and, later, of industrial power supplies and medical imaging power systems. The name of the company was
changed to Crown International in 1975.
In 2000, Crown International was purchased by Harman International, primarily for Crown's Pro Audio
division. As the Crown Broadcast division was not central to the vision of Harman International, remaining
members of Crown's founding family secured the Broadcast division as a separate entity and brought it under
the newly resurrected corporate name of International Radio & Electronics Corporation (IREC).
Today, Crown Broadcast continues to fulfill its mission to provide Best-in-Class FM broadcast transmitter
equipment to its customers by providing highly robust and reliable transmitters worldwide. Crown Broadcast
and WorldCast Systems entered into an agreement allowing Crown Broadcast to add WorldCast’s Ecreso
line of transmitters for distribution, service and support domestically. We believe this will allow our valued
customers the ability to select from a very diverse and fully featured line up including our current product,
now called the Classic line, and the new “E” Series products which will meet all customers’ needs in power
levels up to 10kW’s.

1.2. Before you start
This equipment complies with international mechanical and electrical standards. To maintain this compliance,
as well as to ensure proper and safe working conditions and avoid electrical shocks and fire hazards, you
must comply with the following recommendations:
The device should only be utilized in the conditions described in the user manual.
The device is designed for industrial usage and must only be operated by qualified personnel.
The device may be heavy; it must be lifted and handled with care, specifically during unpacking and
set up.
Electrical precautions
Unplug from mains outlet before any intervention.
Any maintenance, adjustment or repair must be carried out by personnel specifically trained by
WorldCast Systems.
Before switching on the device, make sure the nominal voltage specified on the device matches the
mains nominal voltage.
The device should only be operated on a stable electrical network. If the electrical network is not
stable, a power conditioner, such as a UPS, must be used.
The device must only be used with a plug that incorporates a protective ground contact.
To avoid any risk of electrocution, the protection conductor must not be cut, intentionally or
accidentally, either on the device or on the power cord.
High quality shielded cables are mandatory.
Environmental precautions
It is necessary to verify that environmental conditions comply with those recommended in the
manual.
Nothing must obstruct the ventilation.
To avoid any electromagnetic interference, the device must only be used when it is closed, installed
in a cabinet and connected to the earth ground as per the instructions.
The device should not be exposed to dripping or splashing and no objects filled with liquids, such as
coffee cups, should be placed on the equipment.
Connectors may be hot on high power units.
Precautions regarding the lithium battery
This device includes a lithium battery.
If the battery is not correctly replaced, there is a risk of explosion.
Only replace it with a battery of the same type. Contact Crown Broadcast before attempting to use another
type.
Do not puncture the battery
Do not throw the battery in fire
Do not immerse the battery in water
Do not throw away the used battery, recycle it instead. You may send it back to us if needed.
If these precautions are not followed, the guarantee will be void.

2. DESCRIPTION
2.1. General description
Combining the very latest technologies with our proven RF experience, our 20 W and 100 W exciters have
been designed to offer an innovative and highly reliable solution.
Among the first FM transmitters based on 6th Generation MOSFET, these transmitters are not only more
robust, they also deliver efficiency of up to 74%. Top signal quality and performance are achieved thanks to
the “FM Band Direct to Frequency” digital modulator which is at the heart of this range.
The manufacturing quality and the simplicity of use make these truly powerful transmitters to broadcast
analog FM programs.
The Crown Broadcast FME 20 W and the Crown Broadcast FME 100 W are fully protected against
overheating and VSWR.
They also offer a number of built-in functions that can eliminate the additional cost and space requirements of
external equipment.
Fully featured for local maintenance and configuration, they also allow full remote control by Web server,
SNMP, RS232, or GPIOs*.
* Options available with the current version are:
Basic RDS: The internal RDS encoder makes it possible to manage basic RDS parameters (PI, PS,
TP, TA, PTY, MS, DI, radiotext, PTYN, group sequence, AF, 1 PSN, 2 DSN, dynamic scrolling PS).
GPIO: This additional board allows remote control and management of your transmitter.
TCP/IP: This additional board allows remote configuration via a web site and SNMP management.
Please refer to Appendix A for more information on option management.
Project co-financed by the European Union, involved in the Aquitaine Area,
through the European Funds for local development.
2.2. Accessories
The Crown Broadcast FME is supplied with:
1 power cable
1 serial cable
1 USB cable
2 2A fuses
1 interlock plug + locks
1 box including 1 CD (documentation + PC application) and 1 quick start notice.
