nextraCOM LHX-M5134A/B - 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

Consumption VA 14
Dimension mm 270x200x75
   • 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.
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.
