Product Instruction:
- Install and connect the amplifier according to the equipment structure diagram, and turn on power supply. The power indicator of the amplifier should indicate normally;
- Balance adjustment (SLOPE ADJ): In order to compensate for the level difference between the high and low frequency bands caused by the transmission of cable television signals through a certain length of cable (45-750MHZ high and low frequency attenuation is about 4 times different, that is, when the 45MHZ frequency point is attenuated by 5dB, 750MHZ The frequency point is attenuated by 20dB), please adjust the equalization button to make the amplifier output signal flat;
- Gain adjustment (GAIN ADJ): Too low input level will cause the carrier-to-noise ratio (C/N) to degrade, and too high output level will cause medium to large nonlinear distortion. Adjust the gain button to make the amplifier output level Between 92-100 dBμV.

Uses And Characteristics:
1. When the image quality is not good, the snowflakes can be reduced after zooming in, and the image clarity can be improved.
2. When the signal strength of connecting multiple TVs is insufficient, use this amplifier to first amplify and then multi-channel branch distribution.
3. It can be used in homes, buildings, shopping malls, hotels and other places.
4. Professional device design, low noise and wide frequency band, not only suitable for the current standard of cable TV network transmission, supplementing TV signals, but also suitable for digital signals used in the future.
