FM Radio

The FM Radio tab gives full control over the tuner, Audio Processing, RDS/RBDS mode
and the De-emphasis. These settings provide all the needed adjustments to the algorithm which
DB3010 demodulates and processes the signal.

Antenna RF Attenuator

Could be applied at the FM Input of DB3010, if need be. The available options are Auto, Off,
-10 dB, -20 dB, -30 dB.

RDS/RBDS Mode

Depending on the client's preferences, the deviation could be measured in % [RBDS] or in kHz
[RDS].

Tuner Frequency Step and De-emphasis

User defined frequency step and De-emphasis could also be set, where the default values are 50
kHz Frequency Step and 50 µs De-emphasis.

Audio Processing

If set to Auto, these settings depend on the quality of the received signal (RF Level, Multipath,
and etc.). If any changes in the signal are detected, the unit will automatically adjust to the correct
values.
Stereo Blend – reduces the stereo separation if the received signal is bad;
•
High Blend – applies low pass filter to the L-R audio levels;
•
High Cut – applies low pass filter to the L+R audio levels;
