Multibridge Extreme works with “Funkhausnorm”?
Hi Luke!
We would like to buy a “multibridge extreme”. This has analog audio outputs for the monitoring. Now your hardware works completely according to SMPTE standard. Thus “+24dbu = 0dbFS”. Here in Germany we work according to standard called “Funkhausnorm”. Thus -9dbFS = 0db (+6dbu). We get the record-tapes in such a way, equally we deliver so our master-tapes. In this case our analog audio output is completely overridden. We would like gladly that with -9dbFS in the timeline of finalcutpro our similar peak meter https://www.rtw.de/cgi-bin/rtw_data.pl?CatNo=1119G&LANGUAGE=en indicates 0db. Like that it would be correct. Please you that it gives apart from the SMPTE still different regional standards, understand DIN, British, Nordic thus for example.
Perhaps would a firmware update be possible for our analog/digital-digital/analog transformation common in Germany? Or an individual attitude in the PreferencePanes?Here times an illustration, which I sent already once in former times to you.

Yours sincerely,
Nico Sandhof

Hi Luke,
Look here that is in Germany importantly:
“Reference level +6 dBu @ -9 dB FS” – that is “Funkhausnorm” (Radio house standard 😉
https://www.rtw.de/cgi-bin/rtw_data.pl?CatNo=10-200&LANGUAGE=en -
very popular German manufacturer Behringer has 0 VU to +4dBu which corresponds to -20 dBFS for Sony VTR’s.
based on this, an analog signal of +24dBu would show +20VU, or 0dBFS.
This is an international standard, used by manufacturers in Europe, the US, Germany and Japan.
I can’t imagine any manufacturer changing this standard, and I am surprised that this -9dbFS = =6dBu in Germany. I do work with Siemens in Germany , and have never heard of this.

Isn’t this all academic anyway?
I do as well work with German Broadcasters all the time and for DigiBeta I put down -20 dB as reference tone and program peak at -10dB (and write this down on the ‘Maz-Karte’/Tape-Report). For Beta SP it’s -9dB ref and 0 dB program peak. I’m in Australia so my VTR’s are set to +4dB (against +6dB in Germany), BUT this has nothing to do with the signal on the tape , but only how the VTR inputs/outputs the signal (that’s at least what I understand from my techo).
So whatever signal comes out the Multibridge (or any capture card for that matter) is not important as such but you have to adjust the levels according to your recording device. If digital to DigiBeta it’s a one to one relationship (what you see on the computer meter will be the same on the VTR meter), If analogue you just have to set your output to the references requiert by German Broadcaster’s (-9dB ref/0dB peak). If somebody puts that tape into their machine in Germany it will have the exact same levels no matter of the VTR setup or Multibridge setup (if the VTR is calibrated correctly)
Thing of it as (forgive me techno savy people as this might be simplistic 🙂 that all this dB mumbo jumbo is only about how a say 1 volt signal on the video tape is converted to dB. On the tape its always 1 volt.
Hope that helps

Very interesting to it the following two official products:
https://www.rtw.de/cgi-bin/rtw_data.pl?CatNo=11519G&LANGUAGE=en
(Adjustable headroom marker from -6 dB to -15 dB in steps of 1 dB)https://www.rtw.de/cgi-bin/rtw_data.pl?CatNo=11519G-DIN&LANGUAGE=en
(Scale similar to the DIN 45406 scale (+5 dB to -50 dB).,
Usually corresponds here: “+6dbu = 9dbFS”)Something reading (German):
“FUNKHAUSNORM PEGEL
