Please check our current RDS encoder offer.
The PIRA32 was introduced in 2004 and it was world first compact dynamic
RDS encoder. It was also implemented in many products of 3rd party manufacturers. With more than 15.000 devices and implementations overall it is still probably the most common FM broadcast RDS encoder.
- Fully dynamic stand-alone RDS encoder
- Direct digital RDS signal synthesis
- RS-232 control interface based on set of simple ASCII
commands or UECP protocol
- Control software includes a powerful Windows GUI application
- Text features include dynamic PS, parsing, scrolling,
fixed messages and scheduling
- Two switchable program sets (with optional DSN and
PSN setting)
- Bypass relay, high reliability
- External TA and Program switch
- Switchable MPX loopthrough
- Internal real-time clock incl. backup battery,
showing real-time also as PS
- No special 19 kHz input needed - pilot tone
internally recovered from MPX signal
- Digital 57 kHz phase locked loop - rock stable RDS
subcarrier in all cases, the PLL will never lock to a pilot frequency outside the
functional range
- Easy and fast set-up

| How to
connect the PIRA32 to a computer? |
The RDS encoder can be connected to a computer via
USB adapter cable or standard serial cable terminated by CANON D-SUB plugs.
As a next step, download or purchase appropriate Windows control software.
For more information and set-up details download the manual or see the Magic RDS help.
