Summary: DLC-GX series field bi-directional trunk amplifier is mainly used on bi-directional trunk transmission of TV signal including CATV video signal, digital TV signal and data (or compressed data) signal. The advanced design, scientific and reasonable structure, exquisite material and high performance ATC control circuit make them be the first choice of large or middle size CATV network construction. Characteristics: 1. Adopt Philips or Motorola imported module with low noise, high output level, well non-linearity. Reverse gate adopts Philips or Motorola return-pass unique amplifying module with low distortion and high S/N. 2. Insertion type double effect wave filter, fixed adjustable equalizer and attenuator, Insertion type output splitter or coupler. Scientific online inspecting port to facilitate engineering debug. 3. Aluminum casting waterproof shell, High reliable power switch and anti-thunder system fitting for safe steady work in worse weather.
