Podrobný popis

Terra ma420 R82520 is a top class amplifier of FM, VHF, and UHF signals. The output signals can then be distributed in large MATV systems - in multifamily buildings, hotels, public buildings, etc. Its high gain (30 dB) and maximum output level of 118 dBuV allow for building very large systems.
The device has been designed for cooperation with at420 R82510 channel amplifiers and mt420 R82515 modulators.
Each path is equipped with a dedicated potentiometer for smooth gain reduction. Additionally, the output level of the signals in any of the three bands can be instantly reduced by 10 dB with an appropriate switch.
The amplifier can be powered with a 12 VDC power supply with minimum current capacity of 0.48 A (for one unit). In the case of a greater number of the units, the best choice is the dedicated power supply DR-60-12 R82532. The ma400 amplifier has the ability to power masthead preamplifiers (12 VDC, in each path, with total current consumption up to 100 mA).
The unit can be installed on a wall (with the wall mount), or placed on universal DIN rail R82538 in a 19" RACK cabinet.
Distinguishing features
  • Three independent paths (FM, VHF&DAB, UHF)
    • 3 separate inputs,
    • individual gain adjustment -15...0 dB,
    • individual attenuators -10/0 dB,
    • each path with preamplifier power option (12 VDC, 0.1 A max),
  • Max gain: 30 dB,
  • Max output level IMD3: VHF 116 dBuV; UHF 118 dBuV,
  • DIN rail mountable, also in 19" RACK cabinets.
