Why Choose STL-10 STL Transmitter and Receiver for FM Radio Station?

Why STL-10 Studio Transmitter Link Equipment?

STL10 Studio to Transmitter Link / Inter-city Relay is a VHF / UHF FM communications system providing a high-quality broadcast audio channel with a variety of optional bands. These systems offer greater rejection of interference, superior noise performance, much lower channel cross-talk, and greater redundancy than currently available composite STL systems.

What You Should Know About Studio Transmitter Link

A studio-transmitter link (or STL) sends a radio station’s or television station’s audio and video from the broadcast studio to a radio transmitter or television transmitter in another location.

This is often necessary because the best locations for an antenna are on top of a mountain, where a much shorter tower is required, but where a studio is completely impractical. Even in flat regions, the center of the station’s allowed coverage area may not be near the studio location or within a populated area where a transmitter would be frowned upon by the community, so the antenna must be placed several miles or kilometers away.

Depending on the locations that must be connected, a station may choose either a point-to-point (PTP) link on another special radiofrequency or a newer all-digital wired link via a dedicated T1 or E1 (or larger-capacity) line. Radio links can also be digital, or the older analog type, or a hybrid of the two. Even on older all-analog systems, multiple audio and data channels can be sent using subcarriers.

Benefits You Can Not Resist

  • Synthesized from 220 to 260MHz, 300 to 320MHz, 320 to 340MHz,400 to 420MHz and 450 to 490MHz
  • The transmitted and received frequency can be easily set by digital front panel
  • Suitable for digital audio. The subsonic over modulation and the low-frequency phase distortion are controlled by a feedback circuit in order to exalt the audio quality of the latest digital systems.
  • Low THD distortion: the THD value with stereo or mono demodulated and deemphasized signals is negligible.
  • Flat frequency response: due to the latest generation technology and the component's precision the flatness of frequency response is absolute.
  • Low noise: the excellent signal-to-noise ratio either in mono or in stereo allows the use of this STL¡ˉs in multi-hop networks without decreasing the audio quality.
  • High sensitivity: it allows to reduces the STL’s antenna investment.
  • Great RF immunity: allows operating in most hostile RF environments.
  • High adjacent channel rejection: obtained thanks to the excellent mechanical shielding and the precision of RF filtering.
  • High-frequency stability with the internal temperature compensated crystal reference.
  •  Integrated LCD Display: complete diagnostic and measurement of front panel LCD displays.
  • Integrated information display and protection controls: for all transmit parameters and protection for malfunction.
