Product catalog summary

Introduction
ISOCAST is a high-performance FM digital modulator designed for professional isochronous and isomodulated applications. It utilizes advanced digital technologies to ensure high-quality and reproducible signal processing from low frequency to radio-frequency. The system supports direct to channel technology, generating composite signals from L & R audio inputs and accepting digital AES/EBU audio signals. It also functions as an RDS generator with a user-friendly web interface for real-time content updates.

Key Features
The ISOCAST includes balanced analog audio input/output on XLR connectors, unbalanced digital AES-EBU input/output on BNC connectors, and two MPX inputs for auxiliary sub-channels. It offers a digital delay feature, RDS Open Data Application, and supports Audio OverIP and Synch OverIP. The integrated GPS ensures signal synchronization and stability. The RF output is directly on channel 87.5 MHz to 108 MHz, with optional AES-EBU digital standard output. Remote management is facilitated through a web interface and various protocols including SNMP and UECP overIP.

Block Diagram
