SDI Distribution Amplifier

The Best SDI Distribution Amplifiers (2021)

Last updated

This is a list of the SDI distribution amplifiers I recommend and use.

But first...

What Is A Distribution Amplifier?

SDI distribution amplifiers are a one to many solution.

A single video input is split, or distributed, to every output. And every output will appear exactly the same.

Let's get started.


Blackmagic Design Mini Converter SDI Distribution

Blackmagic Design Mini Converter SDI Distribution

NEW Top Pick For 2021!

This is about the best bang for the buck when you consider price per output.

Very popular and reliable choice for quite a few years.

Available in both HD (up to 3G-SDI) and 4K (up to 6G-SDI) versions.

Formats: Broadcast formats up to 1920 x 1080 at 60 fps (HD version) or 4096 x 2160 at 30 fps (4K version)

My Favorite Feature: Price

Apantac DA-2HD 1x2 Passive SDI Distribution Amplifier

Apantac DA-2HD

Passive 1x2

A sweet little 3G-SDI 1x2 distribution amplifier that doesn't require power.

This makes a handy splitter for situations where you just need a shorter SDI run split 2 ways.

If you only need 2 outputs, your cable runs are fairly short (less than 50% of the cable's maximum rated SDI transmission distance), and don't want to mess with power supplies, this is your answer.

Formats: Broadcast formats up to 1920 x 1080 at 60 fps

Inputs: 1 x 3G-SDI

Outputs: 2 x 3G-SDI

Re-Clocking: No

My Favorite Feature: Size? Weight? Cost? All 3? Yes.

Monoprice 3G-SDI 1x8 Splitter

Monoprice 3G-SDI 1x8 Splitter

Budget-Friendly 1x8

It has a power port, a single 3G-SDI input, and 8 3G-SDI outputs. That's it. No frills.

However, I would hesitate to call this a full "distribution amplifier".

The common complaints I have seen about this specific unit are related to dropped signals, which leads me to believe this probably does not re-clock the input signal before sending it to the outpus.

So with that in mind, if you just need a simple 1x8 to distribute some short runs or you want to use this in a situation that is not critical, this may be a decent fit.

Formats: Broadcast formats up to 1920 x 1080 at 60 fps

Inputs: 1 x 3G-SDI

Outputs: 8 x 3G-SDI

Re-Clocking: No (I have never been able to find a definitive answer to this question, not even from Monoprice, so this is my assumption.)

My Favorite Feature: Price

Decimator Design MD-HX HDMI/SDI Cross Converter with Scaling & Frame Rate Conversion

Decimator Design MD-HX

3G-SDI 1x4 And More

This has been the Swiss Army knife of HDMI/SDI conversion for many years, and it can easily be used as a simple 1x4 distribution amplifier.

The added HDMI/SDI conversion and scaling capabilities make this a super versatile box to have.

Formats: Broadcast formats up to 1920 x 1080 at 60 fps

Inputs: 1 x 3G-SDI

Outputs: 4 x 3G-SDI

Re-Clocking: Yes

My Favorite Feature: Versatility

Theatrixx xVision SDI DA 1x4

Theatrixx xVision

The Crème De La Crème

Wow! Theatrixx is taking video converters to a whole new level.

The integrated power supply (no external power bricks or wall warts), integrated AC outlet, protected ports, and clever mounting options are just a few of the tricks up Theatrixx's sleeves.

If you need tour grade durability, this is what you've been waiting for.

Formats: Broadcast formats up to 1920 x 1080 at 60 fps

Inputs: 1 x 3G-SDI

Decimator Design 12G-Cross
