I NFORMATION Section 1—Getting Acquainted This section provides a general description of the FM10000 transmitter system and introduces you to safety conventions used within this document. Review this material before install- ing or operating the system. Getting Acquainted 1–1...
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 reliabil- ity. The FM10000 package has five (5) PA2000-10K amplifiers, three (3) 5,600 watt power supplies, a transmitter controller, a low pass filter and an optional FM250.
65 x 24 x 29 (cabinet only) Overall dimentions : 83 x 27 x 29 (including external filter) FM10K cabinet (950 lbs) Weight: FM10K shipping weight (997 lbs) Note: System performance is specified using Crown Broadcast Model FM250 Exciter where applicable. Getting Acquainted 1–3...
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.
Section 2—Installation This section provides important guidelines for installing your transmitter. Review this information carefully for proper installation. 2–1 Installation...
2.1 Operating Environment You can install the FM10000 transmitter on any flat surface which should be clean and well-ventillated as possible. 2.2 Tools Required To install the FM10000, you will need the following tools: Medium phillips screwdriver Small flat-blade screwdriver...
2.4 Installation 2.4.1 AC Power Input Block WARNING Possible Electric Shock Hazard! Do not connect AC source until all other connections are made and installation is complete. Remove the 4 screws and the AC block cover as shown in Illustration 2-11 for access to the AC input block.
The Audio input connection is an XLR Female on the back of the FM250 as shown below installed in the rack in illustration 2-14. Analog L and R : XLR Left and Right AES/EBU Input : XLR Left only (with optional DP-3) Illustration 2-14 Audio Input connection FM10000 User's Manual...
2.5 Remote I/O Connections The I/O connections on the back of the controller consist of 3 main ports; Port A (DB-25 Female), Port B (DB-37 Female), and Port C (DB-37). Port A has the metering and control of the System as well as the metering for PA5 (bottom PA).

11. Use the PA1 through PA5 power controls to limit the amount of power output the transmitter can achieve. The FM10000 is set to limit at 11000 watts in the preset condition. For settings lower than this, adjust each PA control counter- clockwise in small equal increments to the desired level.
Transmitter Controller is in the 'Local' mode. The switch in the ON position (up, or 1) will enable the supplies and illuminate the red indicator LED. The switch in the OFF position (down, or 0) will disable the supplies and extinguish the red LED. See illustration 3-3. 3–4 FM10000 User’s Manual...
3.3.3 Transmitter RF Power Control The Transmitter Controller has the ability to internally set the maximum RF output power for the 10000 watt system using the power control setting for each PA. These controls are located behind the front panel and have an access hole in front of each control.
However, it is recommended that an external watt meter be used for a more accurate reading. See illustration 3-5 for the location of the panel meter and selector switch with accompanying green LED indicators. Illustration 3-5 RF Power Reading and Selector Switch FM10000 User's Manual...
3.4 Rear Panel connections The Transmitter Controller has several types of connections on the rear panel of the unit. The following will describe each type and what it is used for. See illustration 3-6 for location of each connector. Refer to Section 2.4.5 illustrations 2-15, 2-16 and 2-17 for detailed descriptions of each applicable remote control connector.
3.4.4 BNC Connectors The Transmitter Controller has provisions for two BNC connectors on the back panel labeled Fwd and Rev. Both of these connectors are used in the FM10000 to receive DC voltage readings from the directional coupler located internal to the output combiner.
