overcome the noise of the treble frequencies the Emphasis can be set to
Flat
,
50μs
or
70μs
.
Injection levels
The MPX signal is a combination of Audio, Pilot and RDS Signal. This option allows you to
adjust the amount of each signal included in the MPX. The recommended and default values are:
0dB
Audio gain
,
7.5kHz
Pilot
and

MPX limiter
Settings> MPX
The regulatory authorities, in some countries, require the total MPX Power not to exceed
0dBr
. Therefore, DB7001 has a built-in MPX ITU limiter that restrains the deviation below the
predefined threshold. The default threshold is
0dBr
.
