Eagle 2000 – 2kW FM Broadcasting Amplifier
User’s manual – Page 5 of 66
1 INTRODUCTION
Congratulations for your choice! Eagle 2000 is new-concept, FM broadcasting solid state (MOS-FET), wide-band 2.000 W amplifier.
The system is so compact it can be entirely fitted into a 19" 2 unit rack 500 mm depth, which makes Eagle 2000 the ideal solution for
medium power repeaters in unattended stations, in N+1 systems and also as a spare amplifier. These are only some of the state-of-
the-art features that make the Eagle 2000 a truly unique device:
Ultra compact size and reduced weight (15 kg).
Thoroughly modular construction. The R.F. amplifier is composed of 3 ultra-compact new-generation internal modules.
Such modules are easy to identify and inspect.
High reliability. Thanks to the internal balance circuits, in case one of the three internal modules fails, the other modules left
are automatically re-balanced, thus to continuing the operation at reduced power.
Better reliability. The rated output power (2000W) is reached at the 80% of the maximum output power the equipment can
generate (2400W).
Low operation costs. The special care taken in the design, aimed at minimizing internal losses, allows a very high electrical
efficiency to be achieved thus minimizing power consumption and thereby reducing operation costs.
High ventilation and low heat sinking. The reduced internal losses and high overall efficiency minimize heat sinking. As a
result, the size of the internal ventilation system can meet even the most demanding environmental conditions.
Large allowable bandwidth and low maintenance requirements.
Interactive control panel with LCD display. Enables the user to set easily the equipment modes and commands and to
display the operation parameters through the practical multifunction knob.
Sturdy modular mechanical and electrical construction. It guarantees a high MTBF and an easy maintenance.
High efficiency. To control the output power level the output power loop control adjusts first the power supply voltage of the
MOS FET and, if it’s not sufficient, it adjusts the Bias voltage.
Continuous control of the cooling fans speed. This control allows a constant temperature of the amplifier heatsink, and a
longer lifespan of the cooling fans.
Automatic reset when an active alarm ends. When an active alarm ends, the equipment is able to automatically reset itself,
without the need of human intervention.
Simple diagnostics and unambiguous parameters reading. This is due to a comprehensive metering and alarm section on
LCD display. Thanks to the optional external telemetry system (available with the next version of Eagle 2000), parameters and
alarms are easily accessible from remote posts through the relevant remote control input.
Compliance with the strictest norms. The equipment was designed in compliance with the tightest international norms, as
well as the recent, strict anti-magnetic noise EC requirements. Besides, the equipment complies with the EC and ETSI
302.018-2 v 1.1.2.1 (2006-03) standards.
