MPX SETTINGS SCREEN
MPX Source
– Set the preferred MPX Source. The following options are available:
•
[Raw MPX] – demodulated MPX received from the Main Station station;
•
[Stereo & RDS Gen] – MPX generated from the built-in Stereo and RDS Generator;
•
[Calibration Tone 400Hz] – single tone of 400Hz, used for calibrating of the inputs of the
devices connected to the MPX output.
NOTE:
Raw MPX is used only when Main Station is the current audio source. Stereo & RDS
Gen is used automatically for all other audio sources. Calibration Tone is active regardless of the
current audio source.

MPX ITU Limiter– The regulatory authorities, in some countries, require the total MPX Power
not to exceed 0dBr. Therefore, DB7007 has a built-in MPX ITU limiter that restrains the deviation
below the predefined threshold. The default
Threshold
is 0dBr.
