Hello all,

 

I am looking to finally purchase the decimator, as an upcoming project is going to necessitate one. (Shooting on the epic, and I only have an SD monitor for now).

 

I am not 100% sure how the decimator works exactly, so I wanted to make sure I asked the right questions before jumping in. 

 

1. How does the unit receive power?

2. Should I purchase the decimator 2, or try to find a used model 1?

3. What is the standard way of mounting the decimator to the rig - just velcro?

4. Is it simply BNC to BNC?

5. Are there other devices I may want to consider that perform the same functions? (I have heard the black magic updowncross is an alternative)

 

 

Thank you all! 

- Kevin

Hi Kevin,

 

1.) DC „locking“ connector. You´ll have to get a custom cable which connects to your rig.

2.) Buy a new decimator 2. Maybe you´ll need the warranty, the decimator is not the most reliable tool.

3.) Velcro is fine if you got enough flat space on the back of your monitor.

4.) It´s BNC to BNC

5.) The problem with the Blackmagic is input voltage. The Blackmagic is made for 12 Volt. A fully charged LiIon outputs 16 Volts or more. The Decimator has a range of 5 to 22 Volts.

Klaus,

 

Thanks for your input. As I'm still fairly new to steadicam, could you elaborate more about the voltage?

The new Black Magic converters can handle unregulated power from a brick with no problem. They fixed that issue a couple years ago. I know this because I bought my black magic converter about two years ago. I plug it directly into 14.4 V bricks with no problems. You may also want to look into the Atomos Connect.

*Not ALL Blackmagic Mini Converters will take more than 12v* You can look on the website on the comparison page and it will tell you what the tolerances of each are.

 

The SDI to Analog Downconverter still wants just 12v.
