Amplificator de canal programabil Telmor WWK-951

The digitally programmable multiband amplifier WWK-951 has been designed for distribution of analog (PAL) and digital (DVB-T) TV channels, as well as DAB and FM radio broadcasts. It is mainly used as the active component of MATV/shared antenna systems in detached houses, residences, hotels, boardinghouses/pensions, recreation centers, schools, hospitals etc.The amplifier is especially useful in places with difficult reception conditions where antennas receive signals from different directions, with disparate levels. The use of the amplifier allows for strengthening and equalizing the signals. The UHF 1 and UHF 2 inputs use five independent band filters (paths) with adjustable width, from 8 to 48 MHz (1...6 TV channels). This feature allows for flexible adjustment of the paths to actual reception conditions at the installation site. WWK-951 amplifier can be used as the basic component ("headend") of a small MATV system, or be used as a part of larger systems, e.g. SMATV systems based on multiswitches.The amplifier can only be installed indoors.In large (S)MATV / shared antenna systems and in very difficult reception conditions we recommend to use highly selective amplifiers Terra at420 R82510. Distinguishing features:amplifier intended for (S)MATV / shared antenna systems,five independent band filters (paths) with adjustable width in UHF band (for inputs UHF 1 and UHF 2),the bandwidth of the paths can be set from 8 to 48 MHz (1...6 TV channels),UHF 1 and UHF 2 inputs can power external preamplifiers,the power status of the inputs is indicated by LEDs,amplifier compatible with analog and DVB-T signals,low power consumption,simple installation and configuration.
