Installation instructions
1. Read the safety instructions first.
2. Mount the amplifier on the DIN rail or on the wall following the mounting instructions listed below.
3. Connections of the cables must be made according to the diagram in Figure 2. There are two ways for power supply
connection: 12 V DC voltage can be supplied through DC input terminal or units of the system can be joined together using
power distribution bus while only one of them connected to 12 V power supply unit.
4. Power supply can be connected only when all connections are finished.
Operating
Input mode can be selected using input mode switch (3). One or two inputs modes are available. The one input mode
offers input test feature, while the two inputs mode enables to summarize and amplify signals from both: RF input and auxilary
input. The amplifier offers wide range of attenuation. Attenuation interstage switch (1) allows to provide output signal level
attenuated by 10 dB. Fine tunning of the output level can be achieved using attenuation rotary switch (2), which broadens
attenuation range up to 15 dB with 1 dB steps adjustment.
