Overview

The Datavideo DAC-91 is a purpose-built audio embedder that lives in the gap between an analog audio source and an SDI video signal chain. It targets event videographers, multicam operators, and small live-production teams who need to fold microphone or line-level audio into an SDI feed without rebuilding their entire signal flow. With four analog inputs presented as two Mini XLR and two RCA jacks, the box accepts a wide range of source devices and embeds two channels into the outgoing SDI stream.

Build quality is geared for production reliability. The DAC-91 automatically detects 3G, HD, or SD-SDI signals on the input, which keeps it format-agnostic across mixed-resolution rigs. Power comes from an included 12V DC AD switch, and Datavideo bundles two Mini XLR to female XLR cables to bridge to standard XLR sources. The unit is covered by a two-year warranty when buyers register the product, otherwise defaulting to a one-year term. For productions that need a small, dedicated embedder rather than a full audio router, the DAC-91 fits the role with minimal fuss.

Pros & Cons

👍 Pros

  • Embeds two channels of analog audio directly into an SDI signal, simplifying camera-to-switcher runs that would otherwise need separate audio cabling
  • Automatic detection of 3G, HD, and SD-SDI signals removes a manual configuration step and reduces the chance of format mismatch on set
  • Four analog audio inputs across two Mini XLR and two RCA jacks accommodate both pro mic-level sources and consumer line-level gear
  • Ships with two Mini XLR to female XLR cables, lowering the cost of integrating standard XLR microphones or mixers out of the box
  • Backed by a Datavideo two-year warranty when registered, giving production teams added confidence for ongoing rental or rig duty

👎 Cons

  • Two channels of embedding will not be enough for productions that require four or eight channels of audio over a single SDI link
  • Analog inputs only means a digital AES feed has to be converted upstream before it can ride along with the SDI video signal
  • Reliance on a 12V DC power input adds another wall wart or distribution cable to plan for in a tightly packed rack or cart
  • Mini XLR connectors are sturdier than 3.5mm but still less robust than full-size XLR for repeated patching on a busy set
  • The two-year warranty period requires registration to unlock its second year, which is easy to overlook during a fast deployment

Frequently Asked Questions

It supports 3G, HD, and SD-SDI signals and detects the format automatically, so the same box can move between camera and switcher resolutions without reconfiguration.
Two channels. The four analog inputs let crews choose which sources feed those two channels, but it is not a four- or eight-channel embedder.
It accepts four analog inputs across two Mini XLR jacks and two RCA jacks, accommodating professional XLR sources and consumer line-level gear in the same chassis.
Yes. Datavideo includes two Mini XLR to female XLR cables in the box, so standard XLR mics or mixer outputs can plug in without additional adapters.
It runs on a 12V DC AD switch that is included with the unit, so production crews need to plan for one additional power outlet or distribution feed in the rig.
It carries a two-year limited warranty, structured as one year plus a second year that activates when the buyer registers the product with Datavideo.
