About This Product

This device is a monitoring receiver that supports digital FM radio station monitoring. By applying the digital signal processing cultivated through our IP codec and digital FM exciter to FM reception processing, we have achieved overwhelmingly high SNR, low distortion, and separation compared to conventional models. This is a purely domestic surveillance receiver that eliminates individual differences and is ideal as a master monitor. Ideal for adjusting the sound quality of digital stereo modulators such as Orban. It has all the built-in features you need as today's on-air master monitor. Outputs on-air signals directly to AES/EBU and analog. Equipped as standard with silence detection function and stop detection (with a make contact for master alarm monitoring as standard), it achieves overwhelming performance.

■Features

・Ultra-compact: The configuration of a conventional analog device, line converter, and AES converter has been consolidated into a 1U size. - High performance: Digital processing ensures clean and pure received audio quality that can withstand broadcasting operations, free from proximity suppression, intermodulation, etc., even in the tight FM bands in today's metropolitan areas. - Versatile: Can be used in a variety of situations, including performance hall master monitoring, transmitting station monitoring, and broadcast wave relay reception. ・Relay station: Conventional broadcast wave relay required expensive RF filters (hardware) to prevent interference, but this unit eliminates these or can significantly reduce specifications, reducing equipment installation costs. Contribute to ・Small individual differences: Compared to conventional analog devices, this device significantly reduces the number of passive components such as capacitors and coils, eliminating model dependence and maintaining quality suitable for a master monitor. ・Startup time: Digitized broadcasting equipment has traditionally had a tendency to take longer to start up, but it is maintained at the same level as analog PLL equipment and can be updated smoothly. ・Quality control: In recent years, the master transmission equipment of commercial FM stations has been digitized, and the AES/EBU signal of the master out is FM modulated through Orban and other digital stereo modulators and exciters before being transmitted on air. . Receiver selection is extremely important for faithful sound quality adjustment and on-air quality control for FM broadcasting.
