Hybrid ME's - which DAAD level calibration for analog hardware chain...?

Hey (hybrid ME) fellows,

what's your DAAD calibration level you're usually working with ?

Or: At which RMS level (dBFS or equalled VU /dBu) do enter your analog chain ?

Thanks for sharing !

I watch for peaks not to exceed -6dbfs .

I'm at 0VU = -18dBFS. Keeps the signal in the sweet spot of most gear without pushing too hard or sitting in the noise floor.

The hottest signal I hit on any of my HW units is approximately -6dBFS. I don’t have any HW units with built-in VU meters, but do have VU meters hanging on the master output, but those are seeing the full range signal and I calibrate that to various targets when mastering for digital, making premasters for vinyl, etc.

depends on the maximum analog i/o levels before clipping in dBu of the analog gear and adda converters: make sure they are matched!

Digital audio sines @ -14 dBFSD from the transfer D/A = 0.775 v RMS AC, here,
whereas 1 kHz @ - 12 dBFSD from the master panel of the DAW = 0 VU, on vintage, transfer path-decoupled, buffered, and damped Sifams.

Hello Uli, my calibration is around +14 - +18dBu.
Most of very good hardware can work up to +24dBu and more.
I set the level in a range were most of the Thresholds will work fine and especially how transformers sounds.

If you use an M/S matrix you have to be careful because of +6dB in the M-Signal (depends on your matrix).
So your right level depends on your hardware devices and their THD on high levels/peaks.

Cal. -14dBFS = +4dBU = 0VU = -14dBFS.

-18dbfs=0VU=+4dbu. Gives me +22dbu before clipping 0dbfs. Dangerous AD+ let’s me get all of that and a db or two while maintaining the integrity of the audio. Neve Master Buss Processor is first in analog chain and has a great analog output meter so I know analog level hitting downstream kit. Usually nothing gets more than 20dbu until last push into AD using the output amp from the Bettermaker Mastering Limiter which is last in the analog chain.

0VU = -18dBFS here as well.

The transfer console we use (MTC-1X) has +/- 10dB of gain for setting up how hard we want to hit various pieces of gear down the line, followed by +/- 10dB of output gain before the convertors. Gives a lot of options.

Using +0 dBm as the nominal signal level for the transfer console leaves 4 dB more headroom than using + 4 dBm. Using gear with low noise makes this a free lunch peak ceiling boost - suggested by A&M's DC.

exactly the same conditions here - gives a lot of options for a lot of different flavours!

As an aside, are users AHM and S_mask the same person?
