Tuner; Tuner Frequency Step And De-Emphasis; Rds/Rbds Mode; Audio Processing - DEVA Broadcast DB3011 Maintenance And Operation Instruction Manual

TUNER

The Tuner 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 DB3011
demodulates and processes the signal.

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 50µs De-emphasis.

RDS/RBDS Mode

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

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 Cut – applies low pass filter to the L+R audio levels;
•
Soft Mute – reduces the level of the audio if the RF level is too low.
