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.

Highlights:

• Synthesized Agility. From 210 to 970 MHz (/3B, /4B, /GHz models) and from 1.35 to 2.5 GHz ( /2G models): the transmitted and received frequencies can be easily set by 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.

  • Meets or exceeds all FCC and CCIR requirements.
  • Low noise. The excellent signal to noise ratio either in mono or in stereo assures the perfect use of this STL 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 RF selective filtering.
  • Full metering:complete diagnostic and measurement of all the main parameters is available using front panel LCD display. Full remote control is available as WEB server and/or SNMP as option.
