Just want to run this passed you guys, I keep having a brain space out.

I have two converters I am going to use, one ADAT'd to the other.


Converter A is 19dBU = 0dBFS

Converter B is 16dBU = 0dBFS

that would give (assuming +4du = 0VU) 15 and 12 db headroom respectively.

I want 20dB headroom.


I run test tone out of converter A at -20dBFS and set my VU meters (attached to this converter as well) to 0VU.

This means my level out of that converter is -1dBu = 0VU (instead of the normal +4dBu)


to achieve parity between the converters, level wise, is where my brain is spacing out. The only thing I can think of is, that 0VU on the second converter has to be -1dBu which means it will have to run it at 17dB head room.


summarise for clarity and less befuddlement

Converter A will have 20dB headroom and its 0VU point will be -1dbU

Converter B will have 17dB headroom and its 0VU point will also be -1dBU

I can see you've been left all alone with no answer to this.

From a quick look your maths seems correct.
