This STL Studio Transmitter Link is a solid-state wideband FM Transmitter providing a continuously variable RF output form 0 to 25 watts into a 50 Ohm load at many frequency within the UHF/ VHF band in 10 kHz increments.

This STL Studio Transmitter Link receiver uses the same synthesised oscillator as the transmitter. A comb line bandpass filter ensures image-frequency rejection exceeding 60dB. The achieved sensitivity in mono is around 10mV per 60dB of SNR. low noise and distortion, and high interference rejection.

With full range universal power input and built-in active PFC function. Those STLs can operate on either 90 ~ 264VAC / 47~63Hz or 127 ~ 370VDC as mean power to suitable most of Countries in the world.

We have designed and manufactured broadcast equipment since its incorporation in 2000. Our product line has consistently applied the best in current technology to the specific needs of broadcasters.
