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 10kWs.

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.

2. DESCRIPTION
2.1. General description
Combining the very latest technologies with our proven RF experience, our 350 W, 750 W, 1000 W, 1500 W,
and 2000 W transmitters have been designed to offer an innovative and highly reliable solution.
Among the first FM transmitters based on 6
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 350 W, the Crown Broadcast FME 750 W, the Crown Broadcast FME 1000 W,
the Crown Broadcast FME 1500 W, and the Crown Broadcast FME 2000 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:
th
Generation MOSFET, these transmitters are not only more
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.

2.3.5. 3U Rack
The choice of stainless steel as material guarantees against corrosion. The rack structure and the structure
of the monoblock front panel reinforce the device. The rectangular outline of the front panel has an LCD
display. The transport handles are mechanically interchangeable and can be removed. The cover is fixed by
a set of M3 POZIDRIV screws and can be easily removed. The user has access to every module to set the
parameters of the device.
2.4. Protecting the transmitter
To ensure the transmitter will work with no risk of damage, a series of protections has been set.
2.4.1. Surge Protector
An optional surge protector module can be added to the chassis. The goal of this module is to limit the surge
caused by lightning. It works after the main protector usually located in the electrical board and before the
power supply protector, thus offering an optimal level of protection. The protector principle is to capture the
surge and divert it to the ground so as to protect the transmitter and its power supplies.
The surge protector used by Crown Broadcast includes multi-MOV technology and a gas discharge tube
(GDT) giving a very high protection and very low parasitic capacitance and leakage currents.
Please refer to Appendix B ‘Maintenance’ for the procedure to replace the surge protection module.

Crown Broadcast FME 350W to 2000W User Manual– 05/2013
2.4.2. Protection against VSWR
Several systems coexist to offer the optimal protection against VSWR:
Hardware protection:
In case of open circuit or short-circuit, the RF is cut. When the situation returns to normal, it is
automatically reset.
Software protection:
The reflected power is limited to 3 W for Crown Broadcast FME 20 W, to 10 W for Crown Broadcast
FME 100 W, to 40 W for Crown Broadcast FME 350 W / 750 W / 1000 W and to 80 W for Crown
Broadcast FME 1500 W / 2000 W.
Software settings for the reflected power security management (see VSWR Trip, section 5.4.1).
2.4.3. Protection against high temperature
The Power Supply module includes its own protector against high temperature. The protector cuts off the
power supply output voltage if the temperature is abnormally high. When the situation returns to normal, it is
automatically reset. The temperature threshold value varies depending on the PSU.
The ambient temperature and the radiator temperature are monitored.
The max ambient temperature is set by software (see menu Temp/Fan, section 5.3.18) Default
value is 50°C. In case of overshoot, a Warning alarm is triggered (Alarm Amb).
The max radiator temperature is set by serial command (see serial command CONF.HEAT.MAX,
section 6.2.3). Default value is 65°C. In case of overshoot, a Warning alarm is triggered (Alarm
Heat).
The max internal temperature is set at 70°C. If the temperature exceeds 70°C, the RF is cut off and
a fault alarm is triggered (Alarm Temp).
2.4.4. Protections incorporated into the PSU
The main power supply voltage and the auxiliary power supply voltage are monitored as follows:
Main power supply:
If the difference between the measured voltage and the expected voltage is greater than 10%, a
Warning alarm is triggered (Alarm Volt1). Expected voltage is automatically computed.
Auxiliary power supply:
Voltage should be either 5, 12 or -12 V. If the difference between the measured voltage and the
nominal voltage is greater than 10%, a Warning alarm is triggered (Alarm Volt Aux).
The amperage is also measured. The threshold varies depending of the power of the Crown Broadcast FME:
2 A for the Crown Broadcast FME 20 W, 8.5 A for the Crown Broadcast FME 100 W, 20 A for the Crown
Broadcast FME 350 W, 23 A for the Crown Broadcast FME 750 W, 29 A for the Crown Broadcast FME 1000
W, 26 A per amplifier pallet for the Crown Broadcast FME 1500 W, 31 A per amplifier pallet for the Crown
Broadcast FME 2000 W. In case of overshoot, a Warning alarm is triggered (Alarm Cur) and the nominal
power is reduced.
