The Blackmagic Design Audio Monitor 12G G3 is a professional, rack-mountable audio monitoring and embedding unit designed for broadcast, post-production, and live production environments. It provides comprehensive audio level metering, monitoring, and manipulation for up to 16 channels of embedded SDI audio. The device allows engineers to visually monitor audio levels on a large, high-resolution color touchscreen, listen to any channel or mix via the built-in amplifier and speaker or headphone output, and make critical adjustments such as level control, phase inversion, and channel swapping.

A core function of the unit is its ability to de-embed audio from incoming 12G-SDI, 3G-SDI, or HD-SDI signals, and re-embed processed or new audio onto an SDI output. This makes it invaluable for fixing audio issues in a live signal path, embedding separate audio feeds, or ensuring correct audio channels are paired with video before distribution. The large 7-inch touchscreen displays detailed bar-graph meters with peak and loudness (LUFS) information for all channels simultaneously, alongside a configurable spectrum analyzer.

Housed in a 1RU rackmount chassis, the Audio Monitor 12G G3 is built for continuous operation in demanding broadcast facilities. It features multiple SDI inputs with loop-through outputs, ensuring minimal disruption to the video signal path. With its intuitive touch interface, powerful audio processing capabilities, and high-quality monitoring, this unit serves as an essential tool for quality control, audio sweetening, and signal management in any professional video workflow.
