The world's first audio processor with the new Audio Processor technology presented at AES convention LAC2022, achieving greater reach with surround sound.
So your radio can have the sound that your competition can't achieve.
The 542 never ages; on the contrary, it improves over time as its software is updated for free for 20 years with the push of a button, without interrupting on-air programming.
Its internal FM monitor analyzes 24 RF parameters and is the only one in the world that also analyzes sound quality (THD, S/N ratio, and stereo separation) automatically and without disturbing the listener.
Complies with ITU BS412 standard and Loudness ITU-R BS.1770 / EBU R128 standard.

FM Modulation Monitor & Analyzer

Data DisplayAll information is remotely read from studios or from any place in the world. You can use standard PCs, Tablets or even cell phones. Usually the first time 542 is on Air Solidyne reads from factory all 24 transmission parameters and adjust Modulation, Pilot tone, RDS signal, Stereo Separation and improves the lack of good separation due to SWR at antenna, coaxial cable and transmitter
On Air Measures during normal programThe 542 can do all the measures, including channel separation, audio distortion THD and background noise during the normal program of the radio station because it is not noticed by the audience
\nUsing an exclusive proprietary technology it works sending to the air very short (few milliseconds) test signals mixed with the voice or music of the program. The digital receiver of the 542 analyzes this brief information in order to convert it to valuable data.
Parameters measuredPercentage of FM modulation in real peak, Carrier frequency, Percentage of 19 kHz pilot tone, Percentage of RDS subcarrier, RF level input (dBuV), Multipath (%), L & R Audio level, L & R Stereo channel separation (dB) , Transmitter and aerial harmonic distortion (THD at 1 KHz), Carrier offset, Ultrasonic Noise (dB Ref carrier), SR at 200 KHz offset from carrier, High and Low side SR at 100 kHz deviation, RDS bit error%, RDS data RT , PS, PTY, PI
Full transmission parameters chartAll transmission parameters data is recorded at a TXT file that can be sent by mail to the engineering department or to the government control authority as a proof of the good transmission quality. Even small damages of coaxial cable or antenna dipoles after storms are detected by the reduction of stereo channel separation.
Radiated Power ChartThe range of a FM radio stations depend on the effective radiated power of the transmitter. The Modulation Analyzer creates continuously a chart of the radiated power. It can be seen at the PC that controls the 542.
\nUsing this unit in European countries it complies with ITU BS 412 standard of reduced RMS power to avoid interference with near frequency FM stations
Automatic mailing of troublesThe 542 internal FM modulation monitor can be settled to send to the station manager or engineer a mail to their PC or Cell Phone in order to inform them about over modulation or 3 sec silence
You will ever be sure about the correct performance of your FM station
