nextraCOM LHX-M8134B / LHX-M8134A - Line Amplifier
It is suitable for use in multi-class trunk signal transmission to compensate or strict distributing network. Adopt Motorola, Philips power double amplifier module. Its main indexes are all better than 34dB gain module obviously. Pre-class adopted low-noise microwave tube double-class push-pull amplifier insures enough gain. 1 input and 2 outputs have over-current protection (fuse plug-change). Branches or distributers at output can be plug-changed freely. Adopt fore-and-aft double equalizers to adjust flatness sensitive and convenient. Import double-layer PCB, a high reliable linearity power and a multi-strict anti-thunder system are set. All these insure long-life and safe work.

Cautions:
  • To insure long-distance transmission flatness and signal to noise ratio in low frequency band, please use fore-and-aft equalizers at the same time for a good effect. If there is a down-concave figure at about 80-200MHz, you may use aft-equalizer and pull out aft-equalizer switch (18).
  • Max gain is the gain when attenuator and equalizer is zero and output plug-in is branch main output.
  • If channel number or amplifiers continuous transmission class number is too many, in order to insure figure quality, decrease output level reasonably.
  • Must use power source with over-current protection. If use magnetism saturation power source, please measure voltage of it with a pointer multimeter, otherwise will cause an error.
  • Finishing installation, please examine whether the circuit is over-current. If you needn't the over-current circuit, pull out the fuse. If need, examine short circuit first with a multimeter.
  • Service: The product installed or maintained by professionals. Any technique consult, please contact MONDO PLAST.
  • BEFORE RUNNING, EARTHING FIRST!!!
  • INSTALL AMPLIFIER WITH INPUT AND OUTPUT CONNECTORS UP !! (HANGING DEVICES UP !!)- AS SHOWN IN PICTURES !
Amplifiers have at oposite side of hanging devices 2 small holes for eliminatig water and condense from the amplifier body. These 2 holes MUST BE UNDER the amplifier body.
