Description Specifications Inovonics 514 INOmini FM Multiplex Decoder/ Radio Broadcast. the Novonics INOmini 514, a standalone decoder designed specifically for FM-stereo multiplex signals. This versatile decoder takes a demodulated FM-baseband input and expertly decodes the signal into discrete left and right channel audio, providing users with high-quality stereo program output. The INOmini 514 offers multiple output options to suit various professional setups. The recovered stereo program is available as a professional line-level balanced output, ensuring optimal audio quality. Additionally, users have the option to access the stereo program as an AES digital audio signal, providing flexibility and compatibility with digital audio systems. Equipped with local alarm ‘tallies’ and selectable de-emphasis curves, the INOmini 514 is an indispensable tool for professionals in a wide range of applications. Whether in broadcasting, audio production, or telecommunications, this decoder provides precise monitoring and decoding capabilities wherever a stereo-baseband signal needs to be decoded and monitored. The inclusion of local alarm ‘tallies’ allows users to stay informed of critical events or signal conditions, ensuring prompt response and effective management of audio signals. Furthermore, the selectable de-emphasis curves enhance audio performance, delivering optimal sound quality tailored to specific requirements. Compact and easy to integrate into existing setups, the INOmini 514 is designed for seamless operation and reliability. Its standalone configuration eliminates the need for additional equipment, making it a cost-effective solution for decoding FM-stereo multiplex signals. Whether you’re monitoring radio broadcasts, conducting audio production tasks, or managing telecommunications systems, the Novonics INOmini 514 offers unmatched performance and versatility. With its precise decoding capabilities, flexible output options, and advanced features, the INOmini 514 is the ultimate choice for professionals seeking high-quality audio decoding solutions.
