Programmable Multiband Amplifier
TMB 200 & TMB 200S
The processing units in the TMB200 range are used to selectively filter digital and analogue UHF channels.
These units also couple and amplify VHF programmes according to the satellite band model (IF).
TMB200 units have 10 UHF filters, distributed over 3 inputs with programmable bandwidth from 1 to 7
channels (8 to 56 MHz), making it suitable for most situations.
An individual setting for each filter or frequency band, and automatic control of the UHF output level, for
aligning service plan levels. Input and interstage amplifiers could be individually set on/off to adapt the unit
gain to the available UHF input signal level.

Important: The unit should only be opened by a qualified technician.
• Disconnect the unit before carrying out any work on it, as some powered components are
dangerous (risk of electrical shock).
• To maintain the temperature of the unit within its normal operating range, ensure the free circulation
of air around the unit (avoid placing it in enclosed spaces). The ventilation grids must be free of any
obstruction.
• Ensure that no liquids can penetrate inside the unit (splashes and/or run off).
• Do not install the unit in a damp place. If there are traces of condensation on the unit, do not use it
until it has dried completely.
• The mains power cable and the HF connection cables must be in good condition and free to move
(neither crushed nor obstructed).
• The mains plug, easily accessible for the technician, must be out of reach of children.
Earthing the unit
• Your aerial installation must comply with the requirements specified by the European provisions EN
50083 (conformity of collective installations) and EN 60065 (standards in force for electrical
protection).
Replacing fuses
• Only a qualified technician can replace defective fuses.
Electromagnetic compatibility (EMC)
• Ensure that the screws on the box are properly tightened.
• Cables and connection terminals should show no signs of rust.
