KatRuud Pira32 RDS, USB, Version 1.0

Discontinued Products.
Producten niet langer in productie.


This is a high performance RDS encoder module, based on the Pira32 RDS encoder design (http://pira.cz/rds/pira32.asp?p=PIRA32_RDS_Encoder_Module)
Ideal for embedding into FM transmitter. Comes fully assembled on a high Quality KatRuud PCB, tested and ready to use.
A High Quality RDS encoder for FM-Broadcast with professional performances.


General (source:Pira):

The PIRA32 RDS encoder is a result of more than 10 years experience collecting and meets requirements of most regional, local, RSL, LPFM and other medium- and small-coverage radio stations. It’s also highly suitable for service and development purposes. Fully digital concept and uniquely effective design ensures high reliability, excellent signal characteristics and gives the user many advanced features while maintaining low acquisition costs. We can say the PIRA32 brought new standard to this branch. It's not a random that couple of manufacturers around the world implement the PIRA32 in their transmission systems.


PIRA32 system features:

Fully dynamic stand-alone RDS encoder

Excellent spectral purity, direct digital RDS signal synthesis, oversampled; tested for broadcast standards compliance

NEW USB control, easy installation, Instructions included

Control software includes powerful Windows GUI application and HTML based system; remote control capability

Firmware updates for free

Addressing feature - independent or common control of up to 255 units in a network

Amazing text features

Advanced weekly scheduling

External TA and Program switch

Switchable MPX loop-through relay, high reliability

Internal real-time clock incl. backup battery, showing real-time also as PS

No special 19 kHz input needed - pilot tone carefully 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
