Studio to transmitter audio link STL DTS–DRS
The DTS and DRS Series are the perfect solution for Studio-to-Transmitter audio links, matching the networking needs of international broadcasters. These products are designed to be frequency agile and to reach the higher audio modulation performances with a very intuitive and complete front panel LCD display control system.
The excellent characteristics make the DTS/DRS series one of the highest quality STL on the market.
Synthesized agility: from 210-970 MHz (3B, / 4B, / GHz models) and 1,35-2,5 GHz (2G models), the transmission and reception of frequencies can be easily set from the front panel LCD display.
Compact, simple, stable: The compact dimensions of the units, the smart internal design for easy maintenance, the very high frequency precision and stability thanks to the temperature compensated crystal are only a few key points for this STL Series.
Excellent stereo separation: A built-in group delay and amplitude precorrector guarantees a very low linear distortion and a great stereo separation in the whole 15kHz band.
Low noise: the excellent signal to noise ratio either in mono or in stereo allows the use of this STLs in multi hops networks without decreasing the audio quality.
High sensitivity: using ultra low noise receiving input amplifiers, selective filters and with a powerful demodulation circuit the obtained receivers sensitivity is very high, so allowing longer link distances with reduced antenna investment also in highly noisy RF environments.
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 channel filtering.
Full metering: complete diagnostic and measurement front panel displays are available. Full remote control is available as WEB server and/or SNMP as option.
Meets or exceeds all FCC and CCIR requirements.
