High-Fidelity Audio Integration

The Datavideo DAC-91 is the essential tool for broadcasters and live producers who need to merge external analog audio with professional SDI video. Whether you are adding a dedicated microphone feed, a soundboard mix, or background music to your production, the DAC-91 embeds two channels of audio with crystal-clear 24-bit precision. Supporting resolutions up to 1080p60, it ensures your video remains broadcast-ready while your audio reaches its destination in perfect sync.

Flexible Connectivity for Any Source

Designed to bridge the gap between different audio environments, the DAC-91 provides both professional Mini XLR and consumer-standard RCA inputs. This dual-input design allows you to connect everything from high-end balanced field microphones to standard media players. The unit intelligently auto-sets compatible formats, ensuring that your external sound sources are perfectly scaled and embedded into the SDI output regardless of the incoming video resolution.

Broadcast-Grade Monitoring and Standards

In professional environments, maintaining correct audio levels is critical. The DAC-91 features a prominent LED audio level indicator, allowing operators to monitor signal presence and volume at a glance. It supports both SMPTE and EBU standards, making it a globally versatile solution for news, sports, and corporate events. Fine-tuning is made simple with physical DIP switches that allow for precise audio level adjustments directly on the hardware.

Rugged, 24/7 Reliability

Housed in Datavideo’s signature heavy-duty metal casing, the DAC-91 is engineered to perform in the "roughest conditions." Its durable chassis also acts as an efficient heat sink, allowing for long-period operation in standard ventilated environments without the risk of overheating. Compact enough for a field kit but robust enough for a permanent studio rack, the DAC-91 is a "set-and-forget" solution for any SDI-based workflow.
