software

  • GSM hybrid control application:

    • GSM Hybrid Control is an application required to configure and control the GSM Hybrid. Input and output levels can be configured in the Settings menu. Making a call can be done with the dial pad window.

    • The application serves as an indicator for SIM card status, call status, and input and output level (PPM) meters.

  • Main window features:

    • The Main window displays the contents of the selected item in the Menu toolbar.

    • You can switch at any time from one view to another by clicking the icons in the Menu toolbar, even if there is an ongoing active call.

gsm_calling
  • Call control:

    • The Call Control section contains the 'call' and 'end call' buttons, colored green and red respectively.

    • Pressing the green call button dials the selected number in the dial pad window.

    • Pressing the red button will disconnect any active call or reject an incoming call.

    • Eight small quick call buttons are provided for calling a phone number stored under one of the memory locations 1 to 8.

gsm_phonebook
  • Phone book:

    • The phonebook stores all contact information in a SQLite database, represented as a single file.

    • The SEND meter indicates the audio level sent to the caller over the GSM network.

    • The meter has a PPM (Peak Program Meter) DIN scale with a fallback of 20dB/1.5sec.

    • The send signal is taken from the SEND XLR input on the rear panel.

    • Your mixing console should create the N-1 (clean feed) for this SEND input.

  • Receive meter:

    • The RECEIVE meter indicates the audio level received from the caller over the GSM network.

    • The meter has a PPM (Peak Program Meter) DIN scale with a fallback of 20dB/1.5sec.

    • The received signal is present at the RECEIVE XLR output on the rear panel.

    • This signal should be fed into a channel on your mixing console.

gsm_equalizer
