Enterprise 12G-SDI 4K Audio Multiplexing & Demultiplexing

The FOR-A USF-101MDX4-12G is an advanced 12G-SDI audio multiplexer/demultiplexer card engineered for installation in FOR-A USF series universal system mainframes. Designed for high-density 4K UHD live production, master control switchers, and mobile OB broadcast vehicles, the card processes signal transfer rates from 1.5 Gbps (HD-SDI) up to 12 Gbps (12G-SDI), providing reliable insertion and extraction of multi-channel digital audio across 4K video infrastructure.

Flexible AES/EBU Audio Processing Engine

Equipped with 8 channels (4 pairs) of AES/EBU digital audio I/O, the USF-101MDX4-12G offers versatile audio management. In Multiplexer (MUX) mode, it maps up to 8 channels of external AES/EBU audio into 16-channel 4K SDI ancillary data spaces. In Demultiplexer (DEMUX) mode, it extracts 8 user-selected channels from incoming SDI feeds and outputs them as discrete AES/EBU digital audio. Built-in Sample Rate Converters (SRC) eliminate timing jitter when interfacing with asynchronous external audio gear.

Low-Latency Synchronization & Timecode Integration

To adapt to varying production latencies, the card offers four selectable synchronization modes: Frame, Line, AVDL, and Line (Min.). An onboard LTC port manages dedicated timecode input and output tracking, while full SNMP support ensures centralized system monitoring and health tracking within compatible USF modular mainframes.
