Hi FAB:
yes I know but this should not matter. I f I record with my Yamaha digital mixer 01v96 via ADAT into my RME interface I have round Zero on the meter Levels on my mixer AND in Cubase the same.
Zero is Zero, no matter what the device calculates or references with in the Background. I mean the interfacing between the devices must deal with this not the user.
You would get mad seeing on every device another “Zero”…

But thank you for your Statement what makes me think About the exact drop in volume… could be the 18 dB…. it is so weird

Hi Peterlanders,

I must say this stuff regarding USB recording an DBFS and DbU can lead to misunterstandigs. What I tried out then was the following (and I opened a ticket at A6H and will post the results of their Research here):

I have a PA System with an AES digital Input and analog XLR Inputs. I hooked up both from SQ6 main XLR Outs and SQ6 AES out.
I played back a song from an iPhone hooked on a Stereo in of the SQ6.
Then I switched AT MY PA-SYSTEM between analog and digital in and had a dramatic drop in loudness Level. I mean, if I drive my PA digitally I loose all the power. This cannot be cause the digital out an in must match.

If I hook up another digital out from another device to my PA, there is no drop between analog and digital in.

Hi New2SQ

I will test this. Interesting point. I come back with my results. THX

Hi Nicole,

first of all: it is amazing that you take care so quickly. I am glad being in the A&H SQ fandom 🙂

Regarding my PA System: It processes the digital inputs and the analog inputs thru the same DSP. In fact, I can switch on the fly between AES/EBU and ANALOG input. So I do not believe that is the problem with the PA.
Another fact is the following:
With the SQ6 mixer connected via AES/EBU to my soundcard it is the same drop of 14 to 15 dB…
Are there different Standards of AES/EBU specifications with different pp voltages or different 0dB levels?

Thank you so much for your support! I will log a ticket now. I knoq this things ( I am an IT guy who did a lot of support and without tickets you bust 😉

Cheerio and tajke care 🙂
