FAQ

Do you wanna a stereo FM transmitter in a professional quality? I know u can do that.

This FM stereo transmitter, using advance modulation system and Phase Lock Loop to control a steady frequency when transmitting. New invented low noise system is used to reduce the noise level during broadcasting time. A digital stereo system is used and control the stereo separation at great condition.with a high gain antenna ,it can easy broadcast anywhere you want, home, apartment, church, school, club, camping, backyard, resident village.This Broadcast Package is plug and Play design, very easy to use, as you could see you could use it at instant.so you really could enjoy the stereo transmitter!


Note:

* Connect antenna first before connecting transmitter to DC supply, otherwise, transmitter will be burned out.

* To set the transmit power, push the power button down and hold it then connect DC supply at the same time. When the LCD screen starts to display H or L, press "+" or "-" button to switch between H and L. "H" stands for 5w, L stands for 1W.
