Telev├ęs reserves the right to modify the product.The product may be different than shown in the picture.

The modulator is equipped with two A/V analogue inputs (CVBS jack), where multiple devices can be connected, such as video cameras, satellite receivers, etc., and is capable of generating two independent output channels.

It modulates the input signals into an IF of 38.9 MHz. The modulated signal is converted into any frequency comprised between 46 MHz and 862 MHz; once filtered, the signal is amplified to reach an output level up to 105 dBμV.

HIGHLIGHTS

  • Two channel generation (Twin).
  • Simple or extended configuration of modulator parameters
  • Controllable both in local and in remote modes.

MAIN FEATURES

  • High C/N level (preserves signal quality in an attenuation range up to10 dB).
  • Response flatness below 1 dB, which allows preserving the relation between the audio and the video carriers.
  • High output level, up to 45 dBmV / 105 dBμV.
  • Preset channel table (CCIR).
  • Full bandwidth outputs, 46 MHz...862 MHz.
