Mini Converter - Audio to SDI 2

The Blackmagic Mini Converter Audio to SDI 2 is a broadcast-grade audio embedder from Blackmagic Design, purpose-built for engineers who need to push 4-channel balanced analog or 8-channel AES/EBU digital audio into a live 3G-SDI signal. It slots cleanly into any workflow under Broadcast Converters & Switchers and delivers SD/HD/3G-SDI auto-switching, 48 kHz / 24-bit sampling, and BNC + 1/4" TRS I/O in a pocket-sized aluminum chassis (MPN CONVMCAUDS2).

Whether you are embedding wireless mic audio into a multi-camera SDI run at a Dhaka wedding, stitching AES/EBU audio from a mixing console into a broadcast truck feed, or feeding clean audio into an SDI switcher for a YouTube live stream, the Blackmagic Mini Converter Audio to SDI 2 removes the usual analog-to-digital handoff pain. It suits BD broadcast engineers whose audio chain is separate from the video chain.

How to Use Blackmagic Mini Converter Audio to SDI 2

Setup

Connect your SDI video source (camera, switcher output, or router feed) to the BNC SDI input on the chassis — the unit will auto-detect SD, HD, or level B 3G-SDI. Plug your balanced analog audio into the 4 × 1/4" TRS jacks, or connect an AES/EBU source to the same 1/4" connectors instead (up to 8 AES/EBU channels). Feed the SDI output to your next device — a switcher, monitor, recorder, or router. Power up via the bundled 12 V DC adapter and you're live.

For live streaming and broadcast

If you're pushing camera SDI into a switcher for a live YouTube, Facebook, or BTV-style broadcast, use the Audio to SDI 2 between your audio mixer and the switcher input. Embedded SDI audio means you only route one BNC cable per camera — no parallel XLR runs, no drift, no phase issues. A Blackmagic ATEM Mini Pro Switcher has HDMI inputs only, so it cannot take this SDI output directly; it needs an SDI to HDMI converter in between, and each of its HDMI inputs carries 2 embedded audio channels.

For multi-camera and wedding workflows

For wedding videographers in Dhaka running several cameras into a central SDI switcher, the Mini Converter Audio to SDI 2 lets you embed mixer audio into any one SDI feed — the clean master audio then travels through the switcher and into your recording output, synchronised frame-for-frame with the video. For converting your analog video alongside, you can add the Mini Converter Analog to SDI 2 to the same rig.

How It Compares: Audio to SDI 2 vs SDI to Audio 4K vs Audio to SDI 4K vs UpDownCross HD

The Blackmagic Mini Converter family covers every direction of audio/video conversion. Here's how the Audio to SDI 2 sits against its nearest siblings in the lineup — all listed in our Converters collection.

If you need a broadcast-rack, 12G-SDI variant for high-end master control, consider the Teranex Mini Audio to SDI 12G — for HD and level B 3G-SDI workflows, the Mini Converter Audio to SDI 2 covers the job. For an HDMI-to-SDI entry point into the same SDI ecosystem, see the Micro Converter HDMI to SDI 3G (with PSU).

Care and Storage

• Keep the chassis in a dust-free pouch when not racked.
• Humid season (বর্ষাকালে) storage: drop a silica gel pack into the gear bag to protect the BNC connectors from oxidation.
• Always power down before swapping SDI cables — hot-swapping 3G-SDI on a powered unit can stress the BNC contacts over time.
• Keep the 12 V DC adapter coiled, not folded sharply.
• Firmware: check Blackmagic Converters Setup every few months for updates.

Frequently Asked Questions

What is the Blackmagic Mini Converter Audio to SDI 2?

It's a dedicated audio embedder from Blackmagic Design that takes 4 channels of balanced analog audio (via 1/4" TRS) or 8 channels of AES/EBU digital audio (via the same 1/4" connectors) and embeds them into the SDI signal passing through it. Output is a single SDI BNC with SD/HD/level B 3G-SDI auto-switching. MPN is CONVMCAUDS2.

How many audio channels does the Mini Converter Audio to SDI 2 support?

Up to 4 channels of balanced analog audio at 48 kHz / 24-bit, or up to 8 channels of AES/EBU digital audio. You choose the input mode in Blackmagic Converters Setup — the unit does not mix analog and AES/EBU simultaneously; it switches between input types.

Does the Audio to SDI 2 support AES/EBU input?

Yes — 8 channels of AES/EBU on the 1/4" connectors. This is the preferred input mode when your audio console already outputs digital AES/EBU, since you skip a D/A-A/D round-trip.

Can I embed analog XLR audio into SDI with this converter?

Yes, with a passive XLR-to-TRS cable or adapter. The unit's analog inputs are balanced 1/4" TRS jacks, but XLR mixing consoles can feed them directly via an XLR (female) → 1/4" TRS cable. Keep runs short for cleanest signal.

Blackmagic Mini Converter Audio to SDI 2 কি 3G-SDI support করে?

হ্যাঁ, তবে 3G-SDI শুধু level B। SD-SDI, HD-SDI আর level B 3G-SDI তে auto-switch করে। আপনি HD switcher বা level B 3G-SDI camera connect করলে unit নিজে detect করে signal format এ lock করে নেয়।

Mini Converter Audio to SDI 2 এ কি power adapter আছে?

হ্যাঁ — box এ একটি 12 V DC international power adapter দেওয়া থাকে, interchangeable plug tips সহ। আলাদা PSU কিনতে হবে না।

Mini Converter Audio to SDI 2 কোথায় পাব Dhaka তে?

Momi Enterprise এর showroom এ — 83/A Bangabandhu National Stadium Market, Dhaka। Online order করলে same-city delivery বা courier এ সারা Bangladesh এ পাঠানো হয়। আসার আগে call করে availability জেনে নিন।

What is the difference between Audio to SDI 2 and SDI to Audio 4K?

They work in opposite directions. The Audio to SDI 2 embeds analog/AES-EBU audio into an SDI signal (3G-SDI max). The SDI to Audio 4K does the reverse — de-embeds audio out of an SDI signal (up to 6G / Ultra HD). Buyers running a 4K pipeline who need both ends may want the Audio to SDI 4K variant instead — see the comparison table above.

Is the Blackmagic Mini Converter Audio to SDI 2 good for live streaming?

Yes — it embeds mixer audio into a live-stream SDI workflow. Route your mixer's master out (TRS or AES/EBU) into the unit, feed the embedded SDI into an SDI switcher (or through an SDI to HDMI converter into an HDMI switcher such as the Blackmagic ATEM Mini Pro), and stream direct to YouTube/Facebook/RTMP. Zero audio-video drift because the audio travels inside the SDI packet.

Does the Mini Converter Audio to SDI 2 auto-detect SD, HD and 3G-SDI?

Yes — the SDI output re-clocker auto-switches between SD-SDI, HD-SDI, and level B 3G-SDI based on the source. You don't have to set the format manually; plug the video source in and the unit adapts.

How do I configure the Blackmagic Mini Converter Audio to SDI 2?

Connect the unit over USB to a macOS or Windows computer, launch Blackmagic Converters Setup (free download from Blackmagic Design), and change settings such as the input mode (analog vs AES/EBU); the mini switches on the unit do the same without a computer. Firmware updates also push through this utility.
