Highlights
  • Separate amplification minimizes intermodulation between bands and provides high output levels
  • Designed using Push-Pull technology, which guarantees levels in the 123 dBμV range for terrestrial signals.
  • Includes a high-performance low-power consumption switch-mode power supply
  • High-screening Zamak chassis The design facilitates appropriate cooling

Main features
  • Pre-equalization and equalization stages
  • Configurable gain for terrestrial band and return channel using two switches (high/low)
  • Intuitive front cover, including adjustments and block diagram
  • Output signal LED indicator

The Cable Equalizer allows to match the signal levels to be amplified at the internal stage of a broadband amplifier, thus preventing intermodulation at that stage. The Pre-equalizer generates an unbalance between high-frequency and low-frequency signals to compensate for the losses in the distribution network.
