  1. Audio Processors for AM & FM • Our advanced technology has improved during 40 years, the sound of the Radio stations in 50 countries • Use arrow keys to change slides •   change slides

  2. We started at 1968 the manufacture of audio processors for radio stations… Our competition at 1968 were CBS Labs, RCA, Gates and Telefunken…. …All those companies disappears from the processor market… Now Solidyne with 40 years of continuous innovations is the world oldest company; then, only Solidyne is able to offer your the largest experience in this field ! 1968-1971 1980 1975 1995 1998 2005

  3. Our superior experience is a guarantee of the audio quality of our processors • The design and manufacture of audio processors is an Art and a Science… It is like manufacturing violins… • We spend many years of research and publication of many scientific papers. Our 40 years of full commitment will help your radio to sound better and to improve your coverage • Now we will show you a brief description of the psychoacoustics involved in audio processing technology

  4. The psychoacoustic process starts at the internal ear Nervous fibers goes to brain

  5. The basilar membrane is located at the internal ear The basilar membrane of 30 mm length, has many vibration cilias connected to about 30.000 nervous fibers

  6. The standing acoustic waves produces excitation of the cilias. The movement activates the nervous fibers • Each audio tone produces excitation according your audio frequency • According to the audio frequency, different zones will be activated 2 pure tones excitation 7 simultaneous tones

  7. In order to get the auditory sensation of strength and loudness, it is necessary the excitation of almost all the basilar membrane

  8. Unprocessed music and voice usually only gives excitation to a couple of bands f1 f2 Position occupied at Basilar membrane

  9. Multiband audio processors elevates the sound energy of all audio bands by individual compression and digital limiting Audio compression Band Filters 20-160 Hz SUM 160-2khz Audio Input OUT 2k- 6 khz Limiter 6k–15 khz

  10. After audio processing all audio bands has high excitation at the Basilar membrane High basilar membrane excitation = loudness sensation Position at basilar membrane

  11. Masking of audio bands Masking of audio due to 3 pure tones of 0,25, 1 & 4 Khz • Masking is the property of the ear to avoid the hearing of some tones due the presence of other tones at high level • This property of the ear allows the processor designers to use high compression ratios without loss of the audio quality • If you are interested in learning more, we recommend you the AES paper: “Multiband Audio Processing and Its Influence on the Coverage Area of FM Stereo Transmission”, by O.Bonello, Journal of the Audio Engineering Society, New York, March, 2007 (www.aes.org)

  12. A good audio processor improves the sensation of audio quality • We spend thousand of hours during 40 years, hearing on air AM & FM transmissions in order to get the best sound quality

  13. A good audio processor increases the coverage area of AM & FM Radio Stations • Audio processing increases the energy of the audio signal • The coverage area will increase between 50 to 80 % • Not convinced ? Please read a scientific demonstration at: • O.Bonello, “New Improvements in… “ JAES vol 24 Journal of the Audio Engineering Society (USA), June 1976 (www.aes.org) • O.Bonello, “Multiband Audio Processing…”, Journal of the Audio Engineering Society, New York, March, 2007 (www.aes.org)

  14. Now we will see the best audio processors… at a price you can afford

  15. Solidyne 562 DSPEvolution Digital Signal Processing • Evolution 562dsp is a five bands audio processor with dual display • Designed for the people that needs the best sound of the market

  16. Solidyne 562dspDigital Signal Processing Other competitive units have intermodulation distortion at high levels • 10 stages of audio processing with 30 preset memories • Option for digital AES-3 in/outs and for internal RDS coder • Advanced 48 bits processing gives the advantage of the bright digital sound, along with the smooth quality of analog sound • The IP models can be connected to Ethernet LAN to be managed remotely from Internet using TCP/IP Solidyne dsp processors cancels at all the IM !

  17. Solidyne 562 DSPDigital Signal Processing • 562 dsp is the only at market that has the excellent audio quality of the high end audiophile audio systems • Please hear our audio demos at Internet and compare…

  18. 562dsp is the world only broadcasting audio processor that includes the 3D sound of the SRS WOW license In 2006 Solidyne sign an agreement with SRS Labs, California, USA for using the SRS WOW special effects technology SRS LABS is a world leader in surround sound and its technology is widely used by the Hollywood Movie industry You can hear an audio demo in our website Using the 562dsp, your Radio station will sound like the Star Wars!

  19. Solidyne 562dsp y 462dspDigital Signal Processing Option TCP/IP IP models have direct connection to Ethernet LAN. You can control processing parameters from Internet When you open the MIC fader the 462 / 562 changes to a voice setting allowing you to get the best sound for your voices Using our exclusive VIRTUAL RACK software you can easily manage from PC all the settings for different musical styles

  20. Solidyne 562 DSPDigital Signal Processing • Adjustment is very easy including icons and block diagrams • It has many factory preset adjustments. You can go on air immediately !

  21. Our exclusive Virtual Rack technology offers you the best way to control a digital audio processor Connecting a PC via serial port or USB adapter, you can create and modify programs from a PC using the software Virtual Rack that comes with each 562dsp This unique system generates on your screen a rack of virtual audio processors to simplify the management of 562dsp. When using automation software, like Audicom, each time a song is reproduced the 562dsp changes its processing parameters according to the type of music Only Solidyne offers you this powerful system !

  22. Solidyne 562 DSPDigital Signal Processing The creation of an audio processor for excellence is based on how the human ear perceives the sounds Manufacturing processors is like to make violins…We do not have 200 years of experience ... but we are the most experienced audio processor factory, researching and manufacturing equipment since 1968
