The BURST 2000A linear amplifier is the device of Class I for protection against electric shock, i.e. the
third power cord ground wire (colored yellow with two green strips) and ground pin on the PA rear panel,
marked GND (Fig. 2-1), must be connected to the house ground system for safety operation.
This User Manual contains safety precautions, cautions and warnings that MUST BE OBSERVED and
COMPLIED by the owner to ensure safety operations and maintenance of the BURST 2000A amplifier.
Precautionary measures
The notes described below refer to this manual:
The WARNING notes draw attention to the procedure that, if not correctly executed, may cause personal
injury or fire hazard if electric shock or lightning strikes. Caution notes pay attention to a procedure that, if
not performed correctly, may result in owner’s equipment damage (not only in the BURST 2000A
amplifier).
Notes NOTE pay attention to the procedure, which, if not performed correctly, can lead to inconveniences.

WARNING! HIGH VOLTAGE!
Both mains voltage and high RF voltage inside the BURST 2000A amplifier! For its safety, disconnect the
mains plug from the mains and wait at least three minutes before removing the cover of the amplifier.
NEVER LET, ESPECIALLY CHILDREN to have something inserted in the body holes - this will
cause an ELECTRIC SHOCK!
Never touch the antenna or antenna isolators during transfer or settings - this may cause ELECTRIC
SHOCK!
Never expose the amplifier to rain, snow or any liquids. Avoid excessive dusting of the amplifier and long-
term exposure to direct sunlight.
Do not block the COOLING by closing the air ducts or air vents.
CAUTION
Do not repair or replace the hardware of your BURST 2000A amplifier. This can lead to health and life
risks. Such repairs are not covered by the warranty.
The manufacturer is not responsible for any repairs performed by any specialists, uncertified by the PA
producer.
PRECAUTION
To avoid damage (not covered by the producer’s warranty!), please read INSTALLATION - section 2 of
this instruction manual. If you have any doubts or questions regarding the installation, operation or safety
of the BURST 2000A amplifier, please, consult the producer immediately as it recommended above.
2. INSTALLATION
2-1. Unpacking and initial inspection
Unpack and carefully inspect the contents of the cardboard box for possible damage during transportation.
Check the housing, the front panel, display, buttons, rear connectors, the main power switch and fuses.
2-2. Amplifier Location Selection and Cooling Conditions
You will need easy access to the rear panel of the Amplifier to connect the cables and to the buttons and
the screen on the front panel as well.
BURST 2000A is equipped with water-cooling. Place the amplifier so that there are no objects or other
devices closer than 10 cm (4 in) from the rear panel of the amplifier.
PRECAUTION
Avoid any contacts with water, metal objects through the ventilation holes.
2-3. Amplifier Connections in the house.
CAUTION
The amplifier can create a significant load (more than 3 kW) on the local electrical network. From the
beginning, verify the ability of your power net to work with such power consumption.
CAUTION
Never use the house gas pipes for grounding. This can cause an EXPLOSION!

6
CAUTION
Do not use the local pipes for heating or water supply for grounding! You can create a dangerous tension
on them. You can endanger not only yourself, but also other people in the house.
PRECAUTION
Remember please, that the ground wire can withstand emergency currents of more than 20 A with a
minimum voltage drop. Therefore, you may need to connect the ground with a thicker wire.
a) GND Bolt – at the beginning, please, connect the ground pin of the amplifier (located on the rear panel
and marked GND - Fig. 2-1) to the house grounding system.
b) Socket “KEY-IN” input of the amplifier to control the reception / transmission from the transceiver.
c) “ALC Connector” – please, connect this socket to the appropriate input of Your transceiver.
d) “RF INPUT” - Connect the transceiver output (antenna socket) to the RF INPUT amplifier socket by the
coaxial cable with PL-259 jack.
PRECAUTION
To avoid any damage, turn off the internal antenna tuner of your transceiver.
e) “RF OUTPUT” – Please, connect RF OUTPUT plug on the back of the amplifier to the antenna or to the
antenna switch by any suitable coaxial cable with the PL-259 jack.
PRECAUTION
If you are using an amplifier for the first time in your home, pay your attention to the marking of the coaxial
cable from the output of your amplifier to the antenna. The cable must be capable of withstanding increased
power, especially at 10m and 6m bands. This warning applies equally to the antenna switch, tuner and the
entire antenna system.
We recommend you use RG213 type cable or better.
f) Check the power switch position. It should be “OFF” for disconnection of the amplifier from your local
power net.
g) Mains fuse.
h) Power cord Socket.
i) Ethernet (LAN) Connector for remote control of the amplifier via PC.

7
2-4. Connections to External Devices (transceiver, computer, etc.)
a) “Control” connector used to connect and work with different transceivers models, as well as to update
the software (see table 2-1).
Most modern transceivers can be connected via CAT or BAND DATA to BURST 2000A. This will allow
the amplifier to monitor the transceiver frequency and automatically change the range and operating modes.
The cable can be ordered in the kit additionally, supplied separately, or independently manufactured at
home in accordance with table 2-1 and the transceiver manual.
Table 2-1 shows the signals and outputs of the “CONTROL” connector - the rear panel of the amplifier.

3. THE PRIMARY ACTIVATION AND OPERATION
PRECAUTION
Do not turn the amplifier on for at least two hours after unpacking and setting it to its final operating
location. Please, pay your special attention whenever the amplifier is moved from a very cold place to a
very warm place, because the water condensation may appear inside of the body, resulting in damage to the
high voltage circuits of the amplifier. Under these conditions, do not turn on the amplifier for at least 4
hours.
After following all the instructions in section 2 "INSTALLATION", check whether the power switch on
the rear panel is turned off. Then plug the amplifier into the local electrical outlet.
3-1. Power saving mode with low power consumption
Now you can turn on the power switch on the rear panel of PA. This only activates the low power standby
mode of the amplifier power supply and the red LED on the ON/OFF button will light up while the main
power supply is still off and the display is dark.
3-2. Front Panel - Control and Display indications
a) “ON/OFF“ Button. When the power switch on the rear PA panel is in the position “ON”, press to turn
on the amplifier. When the amplifier is on, press to turn it off (standby).
b) LED indicator is above the ON/OFF button. When the red light is on and the screen is dark, the amplifier
is in standby mode and can be turned on by pressing the ON/OFF button while the LED goes off.
This LED (b) flashes – it’s an additional indication when one of the internal protection systems is activated..
Pressing the ON/OFF button will reset the protection.
c) There are six (6!) function buttons for manual (local) control of the amplifier. The function of each button
is displayed above it. Depending on the menu displayed, the buttons may have different functions.
d) The color display shows you the full information about PA work conditions.
3-3. Primary Power ”ON”
To start the amplifier, press the ON/OFF button on the front panel - after eight seconds (boot sequence),
the display will show you the main screen - figure 3-2 ,
The amplifier can be started from the standby mode either by the ON/OFF button or by remote control.
