1.1 Your Transmitter Package

The FM10000 is a highly efficient transmitter package designed to set a new standard
in FM transmitter design offering modularity, ease of use, and long-term reliabil­ity. The FM

power supplies, a transmitter controller, a low pass filter and an optional FM250.

FM10000 transmitter package requires no tuning and typically provides 80% RF

The
efficiency
90% efficient. Modern MOSFET technology ensures high AC to RF efficiency
(better than 70% overall typical) and long-term reliability. The unmatched efficiency
of this
operation and lower power costs.

10000 package has five (5) PA2000-10K amplifiers, three (3) 5,600 watt

. The three (3) 5600W power supplies are power factor corrected and

transmitter significantly improves your bottom line by providing cooler

These modular units are uniquely designed to be

simple installation with minimal floor space. Installation is easy with three

and

connections; AC power in, Audio in, and antenna out. In addition, built in metering
and status indicator capabilities enable intuitive operation to further augment
the user-friendly design.

Economic long-term reliability is ensured through our carefully engineered solid­state design.

1.3 Safety Considerations

Crown Broadcast assumes the responsibility for providing you a safe product and
safety guidelines during its use. “Safety” means protection to all individuals who
install, operate, and service the transmitter as well as protection of the transmitter
itself. To promote safety, we use standard hazard alert labeling on the product and
in this manual. Follow the associated guidelines to avoid potential hazard.

1.3.1 Dangers

DANGER represents the most severe hazard alert. Extreme bodily harm or death
will occur if DANGER guidelines are not followed.

1.3.2 Warnings

WARNING represents hazards which could result in severe injury or death.

1.3.3 Cautions

CAUTION indicates potential personal injury or equipment or property damage if
the associated guidelines are not followed. Particular cautions in this text also
indicate unauthorized radio-frequency operation.

Type of Hazard

WARNING

Severe shock hazard!

audio spectrum as opposed to the spectrum influ­enced by the pre-emphasis; also called "Wideband."

carrier A continuous signal which is modulated with a

second, information-carrying signal.

crosstalk In FM broadcasting, this term generally refers to

the interaction between the main (L+R) and the
subcarrier (L–R) signals as opposed to "separation"
which generally refers to leakage between left (L)
and right (R) channels.

density (program) A high average of modulation over time.
deviation The amount by which the carrier frequency

changes either side of the center frequency.

DIP Dual In-line Package; term used to describe an IC

or socket that has two parallel rows of pins.

distortion The unwanted changes in signal wave shape that

occur during transmission between two points.

exciter (1) A circuit that supplies the initial oscillator used

in the driver stage. (2) A transmitter configuration
which excludes stereo generation and audio
processing.

FET Field-Effect Transistor
frequency synthesizer A circuit that generates precise frequency signals

by means of a single crystal oscillator in conjunc­tion with frequency dividers and multipliers.

FM Frequency Modulation; the process of impressing

information on a radio signal by varying its fre­quency.

FSK Frequency Shift Keying; an FM technique for

shifting the frequency of the main carrier at a
Morse code rate. Used in the on-air identification
of frequencies.

gain reduction The process of reducing the gain of a given ampli-

fier.

harmonics Undesirable energy at integral multiples of a

desired, fundamental frequency.

HF High Frequency; Frequencies in the 3.0 to 30.0

MHz range.

Highband Frequencies affected by the pre-emphasis.

modulation The process by which a carrier is varied to repre-

sent an information-carrying signal.

MOSFET Metal Oxide Semiconductor Field Effect Transistor;

a voltage-controlled device with high input imped­ance due to its electrically isolated gate.

nearcast A transmission within a localized geographic area

(ranging from a single room to a several kilome­ters).

pilot A 19–kHz signal used for stereo transmissions.
pre-emphasis The deliberate accentuation of the higher audio

frequencies; made possible by a high-pass filter.

processing The procedure and/or circuits used to modify

incoming audio (keeping its level around 75 kHz
deviation) to make it suitable for transmission.

receiver An option which adds incoming RF capability to an

existing transmitter. See also "Translator."

RF Radio Frequency; (1) A specific portion of the

electromagnetic spectrum between audio-fre­quency and the infrared portion. (2) A frequency
useful for radio transmission (roughly 10 kHz and
100,000 MHz).

SCA Subsidiary Communications Authorization; see

"subcarrier."

S/N Signal to Noise
spurious products Unintended signals present on the transmission

output terminal.

stability A tolerance or measure of how well a component,

circuit, or system maintains constant operating
conditions over a period of time.

stereo pilot See "pilot."
stereo separation The amount of left-channel information that bleeds

into the right channel (or vice versa).

subcarrier A carrier signal which operates at a lower fre-

quency than the main carrier frequency and which
modulates the main carrier.

suppression The process used to hold back or stop certain

frequencies.

ratio of the maximum voltage to the minimum
voltage or maximum current to the minimum
current; also the ratio of load impedance to in­tended (50 ohms) load impedance.

THD Total Harmonic Distortion
translator A transmitter designed to internally change an FM

signal from one frequency to another for retrans­mission. Used in conjunction with terrestrial-fed
networks.
