Overview

The MX2200 handles:
  • A conventional land line (POTS).
  • A mobile phone paired via Bluetooth.
The primary function of both lines is to serve as a backup link to 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 “On-Air” Phone Lines

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

Controls (Land Line (POTS) and Bluetooth)

The following controls apply both for adding calls to the local transmission and for using the lines as a studio link: Mx2200 Telco Pn
  1. PHONE/LINE IN
    • Switches between phone line and stereo line input.
    • With an Internet link, it is possible to operate with 4 microphones and 2 audio sources (LINE IN and USB).
    • If a call comes in on the land line (POTS), the HOLD button flashes. The operator can switch from LINE IN to PHONE and answer the call.
    When there is no Internet and the link is made via Bluetooth, it is not possible to add from PHONE LINE, neither the land line (POTS) nor LINE IN, as PHONE LINE is not added to the mix sent to Bluetooth.
    LINE IN can only be used from its own fader if there is no USB audio.
  2. Phone line / LINE IN level knob
    • Adjusts level in both CUE and PGM.
  3. TALK button (Land Line (POTS))
    • Allows talking in cue with the land line (POTS) using the built-in TALK microphone.
  4. HOLD
    • Indicates incoming call (flashes with the ring).
    • Allows answering and putting the line on hold or sending it to PGM.
  5. CUE/PGM
    • Switches the signal (telephone or LINE IN) between cue listen (CUE) and program output (PGM).
  6. Bluetooth mobile phone audio level control
  7. Bluetooth on/off

  8. Bluetooth CUE/PGM

  9. TALK button (Bluetooth)
    • Allows talking in cue with the Bluetooth line using the built-in TALK mic.
  10. Master headphone control
  11. PGM to Headphones
