SoundCross-M consists of a few modules and uses the apt-X algorithm.
It transmits high-quality audio signals from a studio, and they are used for outdoor broadcasting and relay broadcasting connected to each broadcasting station.
It is a digital/analog multi-channel audio codec device which is connected to the 10 circuits of stereo digital audio signals or analog signals, condenses them into digital signals, and transmits the digital signals to a long-distance emitting device, and vice versa.
It is used for mono or Stereo of FM broadcasting, HD radio and DAB.

SoundCross-M Features

  • The bandwidth of its audio signals supports from 10Hz to 22.5kHz.
  • It uses two E1s.
  • The power unit and the trunk unit are duplicated.
  • It has a function of dual transmission routes.
  • It uses the analog signal or the AES/EBU signal, selectively.
  • In-band Management over E1
  • It can control or monitor a few devices using the Ethernet port.
  • It has a level marking function on its front panel.
  • It can control the receiving level at the analog receiver.
  • It has a function of test-tone emission.
  • It has a function of TPG emission.
  • It has a function of audio and Network loop test.
  • It has a function of generating audible signals.
