1. INTRODUCTION
AH1916H is a 16 modular frequency fixed-channel modulator. It will be up to 16 audio and video signals into a road with 16 TV channels RF signals. The product is widely used in hotels, hospitals, schools, electronic teaching, factories, security monitoring, VOD video on demand and other places of entertainment, especially for digital TV analog conversion, and centralized monitoring system.
2. FEATURES
- Stable and reliable
- AH1916H of each channel is completely independent, channel configuration flexibility
- Image high frequency and RF local oscillator MCU technique are used, frequency stability and high accuracy
- The function of each integrated circuit chips are used, the whole high reliability
- High-quality power supply, 7x24 hour stability

A. Output test port
Video output test port,-20dB;
B. RF output
Multiplexer module modulated, after mixing the RF output;
C. RF output regulation
Knob, adjustable RF output level;
D. Power cascade output
Superposition of multiple modulators, you can cascade output therefrom to other power modulator to reduce power outlet occupation; careful not to cascade more than 5 to avoid excessive current.
