The MT-47 dual-band modulator has a microprocessor control - the selection of the output channel is made after removing the housing with two buttons, and its number (as well as each parameter described below, the value of which can be changed) is displayed on the LED display. The channel number and values ​​of other parameters are stored in the non-volatile memory. The use of a quartz stabilization system (PLL) provides almost zero frequency error. These modulators can be cascaded. They also enable the summation of the modulated signal with the terrestrial TV signal. It is possible to protect the modulator against accidental change of parameters.

Modulator Terra MT-47

The MT-47 modulator is monophonic. It has two audio inputs: for the left and right channels, however, they are added together.
It should be noted that compared to the previous series of modulators, Terra has implemented more variations of the PAL standard.

It is possible:
- vision carrier frequency regulation,
- changes in the depth of sound carrier modulation,
- changes in the distance between the audio carrier and the video carrier,
- adjustment of the input level and the deviation of the audio signal.
These modulators are the perfect solution both in domestic installations and in small collective installations. Extremely strict quality control at Terra makes these devices practically failure-free.
