Description
STL10 Studio to Transmitter Link / Inter-city Relay is a VHF / UHF FM communications system providing a high quality broadcast audio channel with variety 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.

Features
 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 components 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’s in multi-hops networks without decreasing the audio quality.
 High sensitivity: it allows to reduce the STL’s antennas investment.
 Great RF immunity: allows to operate 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 front panel LCD displays.
 Integrated information display and protection controls: for all transmit parameter and protection for malfunction.
