Modulator ISOCAST

ISOCAST is a FM digital modulator for isochronous and isomodulated professional applications. High-performances are obtained implementing the most advanced digital technologies that allow amplitude demodulation without the traditional analog approach. All signals from low frequency to composite MPX generation and radio-frequency, are completely realized in numerical mode, in order to ensure high-standard quality and reproducibility. ISOCAST uses direct to channel technology. It takes the L & R audio signals to realize the composite signal by generating the pilot frequency at 19 kHz. Moreover it accepts a digital AES/EBU audio signal in input. ISOCAST is also a RDS generator with selectable strings. All the standard message types are supported. User is able to change the RDS content on the fly via a user-friendly WEB interface and/or the standardized UECP serial protocol. ISOCAST foreseen two MPX separated inputs 0 ÷ 100 kHz. It is compatible with widespread HTTP and RTSP streaming protocols and Radiolink-to-FM, supporting PCM, MP3 and AAC codecs. ISOCAST contains a GPS receiver useful for synchronizations and tuning of all signals, ensuring stability at channel frequency as well as assuring the issues related to isomodulation for plants placed in overlapping areas. ISOCAST is an efficient modulation system. The ductility of applications both for isofrequential networks and FM modulators, allows a flexible use also through serial/IP based remotization, able to support UECP protocol, OverIP, SNMP and Web server. ISOCAST could be also used like supervisory control. A set of dry contact available on apparatus back allows remote controls.
