Eagle 2000 – 2kW FM Broadcasting Amplifier 5 , , , , CIRCUITS DESCRIPTION This section’s sole purpose is to provide general explanations about the device operation in order to simplify the maintenance by skilled personnel appointed by Quark. As already mentioned, no internal adjustments are required for normal operation. Tampering with the internal settings makes the warranty null and void. Moreover, could seriously damage the equipment, compromising the guaranteed performance.
Eagle 2000 – 2kW FM Broadcasting Amplifier 5.1.b Main power supply switch and power supply relay The main power supply switch triggers a power supply relay rated for the supply current required by the equipment. The power supply unit is connected to this relay. 5.2 R.F. amplifier section The first element of this section is a 3-ways Wilkinson splitter [26] which splits the R.F. input power (30W) into three 10W outputs. These signals are the inputs of three 800W amplifier modules [27].
Eagle 2000 – 2kW FM Broadcasting Amplifier 5.3 Control (CPU) board The control board, located just behind the analog board, stores the software which manages the equipment. Moreover, the built in memory stores the programs used in all models of the Eagle series (please see the bottom note).
Eagle 2000 – 2kW FM Broadcasting Amplifier 5.4 Analog board This board manages all the equipment protections via the output power loop control and the reflected power loop control. On the board there are two trimmers to adjust the direct (RV2) and reflected (RV1) powers shown on the display (e.g. in the working page, Ö9.2), and a third trimmer (RV3) for the adjustment of the maximum output power level (see the following paragraph for information on how to locate and adjust these trimmers).
Eagle 2000 – 2kW FM Broadcasting Amplifier [51] 48VDC power supply for the 800W amplifier module #3 – the (black) power resistor is used for the current measurement. [52] 48VDC power supply for the 800W amplifier module #2 – the (black) power resistor is used for the current measurement. [53] External stand-by input command – coming (if present) from the rear panel. A short-circuit between the two contacts sets the Eagle2000 in stand-by mode.
Eagle 2000 – 2kW FM Broadcasting Amplifier 5.7 Digital encoder (multifunction knob) This board is located in the back of the front panel near the ON/STAND-BY button [1] and the Analog board (Ö5.4). It holds the rotary digital encoder, directly connected to the multifunction knob [7]. The board communicates directly with the Control (CPU) board (Ö5.3), which detects the user commands: clockwise rotations, counterclockwise ones, as well as pushbutton operations.
Eagle 2000 – 2kW FM Broadcasting Amplifier 6 , INSTALLATION Warning: to ensure safe functioning of the equipment, it’s absolutely mandatory to comply with the instructions of the present chapter. 6.1 Checking the supplied parts Before using your amplifier, make sure that the following parts are included in the packing: • The amplifier • The user’s manual (this manual) As an option (to be supplied on demand) there would be a RG58 N-N cable, 1 meter length, to connect the amplifier to the exciter.
Eagle 2000 – 2kW FM Broadcasting Amplifier that the Eagle 2000 internal fans are low-pressure units and therefore an air extractor on the air exhaust duct in definitely needed. • Air conditioning at 20 – 25 °C would obviously be the best solution. Thermal insulation and efficient ventilation with a thermostat-controlled blower are generally the best solution. • Even moisture and/or dust, when excessively present in the air or in the room, may cause condensation build-up in the amplifier.
Eagle 2000 – 2kW FM Broadcasting Amplifier 6.4.c , Connecting to the exciter Warning: The exciting rated power of the amplifier is from 25 to 30W.
