Hi, sorry for bad english, not native.
I have a DB elettronica PM300 , wich is great!
What i don't understand is if i can broadcast some RDS signal with it? what are the SCA for?
Do i have to broadcast in mono to have RDS? as i read about it in your help section?
Thanks much anyway for the VERY good software that i'm gonna buy VERY soon, when my setup will be optimal!
Edit : Here is what i found in the user's manual :
"The new modulator board SINTEL ’96 allows a high quality direct carrier modulation accepting a
composite stereo (MPX) or a mono input signal with up to 3 SCA subcarriers (for example RDS,
The mono input signal is filtered by a 7th order elliptic filter with a very flat response (20Hz to
15kHz with 0.25 dB) and an optimum out of band attenuation (>50 dB for frequencies higher
than 19 kHz), then the signal is amplified (or attenuated) and passed to the VCO oscillator for the
FM carrier modulation. The VCO is controlled by a digital PLL circuit with a high stability quartz
reference to obtain a very stable synthetized oscillation: the frequency setting is customizeable using
on board dip-switches (the minimum step size is 10 kHz).
The composite stereo signal and the SCA subcarriers are just amplified or attenuated by the correct
modulation depth adjustment before going through the VCO stage: the stereo performances of
SINTEL ’96 are excellent, (stereo separation >60 dB from 20Hz to 15 kHz, SNR > 80 dB).
Before the VCO stage, an adjustable and bypassable deviation limiter prevents the FM carrier from
an excessive modulation depth and adjacent channel interference according to all the international
standards (CCIR, FCC). Furthermore, an automatic locking circuit enables the output modulated
signal of SINTEL ’96 only when the internal PLL is locked properly, in order to avoid unwanted
