General Description

The MX2200 handles:
  • One conventional landline telephone (POTS).
  • One mobile phone connected via Bluetooth.
The main function of both lines is to serve as a backup link for the Internet connection.
They can also be used:
  • As the main broadcast channel when Internet is not available.
  • As an audio source to add a call to the broadcast.

​
Using Lines “On Air”

  • Participants (reporters or interviewees) can be added to the broadcast.
  • This can be done with landline or Bluetooth mobile, even while the console is broadcasting via Internet.
  • The line can interact privately with the console operator, and also with the studios when sent to program (PGM).
  • The studio return signal (SIP) is injected into monitoring (CUE) and sent to both landline and Bluetooth.
  • The SIP link return level is adjusted from the screen, in SETUP → RX VOLUME.
Warning!
Conference between landline and Bluetooth mobile is not supported.
It is possible to put both lines on air, but they will not hear each other or be able to dialogue.
  • Once the call is established, the studios always receive the PGM mix through the telephone line.
  • In CUE position, the return signal sent by the Studio is heard only in monitoring. If the TALK button for that line is pressed, the talkback microphone is sent to the studios.
  • In PGM position, the Studio return is removed from CUE and added to PGM.
  • The line send is mix-minus: the Studio return is not added to the PGM being sent back, avoiding feedback.
  • In PGM position, the talkback microphone is not sent to the studio.
  • Therefore, when using the line as a link, it should always be set to PGM, preventing the TALK mic from accidentally going on air.
  • The studio return (audio from the other end) can be heard in headphones by mixing PGM with the telephone line (verify that PGM monitoring is enabled in CUE).
  • If return monitoring is not needed, keep the PGM knob closed.
