Also sometimes referred to as dBv, it is dB referenced to voltage. 0dB equals 0.775 volts.

Reasonably new to this. This question arises from my search for a new/new-to-me preamp to replace my mobilePre
(which, not surprisingly, doesn't provide tracks which stack particularly quietly).

I believe that I understand the concept of headroom (i.e. - how hot a (mic) signal can the preamp handle?),
but not the measurement units.

Hello,
I've recently purchased a dda interface console and am trying to figure out the best way to connect it to my 002r.
The direct outs and inserts on the dda are -2 dbu but the ins on my 002 and external adc are -10 or +4dbu.

I own a Soundcraft Ghost le24 which I use with an 8 track analog setup and I'm looking to upgrade to a 24 track hard disk but would like to know the following from a Soundcraft Ghost user like what's the deal do I have to ride the gain on the channel to +6 to get to +4dbu on my channel strip direct out?

I was trying recently to figure out why 2Vrms is 6.02 dBV instead of 3.01 dBv, and I learned that it is of course because the power in constant-load circuit is proportional to the square of the voltage. So,

dBV = 20 * log (Vmeas / 1V)

I'm going to buy a new soundcard. I am going to buy one that has balanced ins, but should I also sure that the balanced ins take +4dbu, or is -10dBV input okay? Will it even make a difference?

My preamp is a Mackie 1202, so I can send my output through either +4dBu or -10dBV.

Thanks in advance for the help.

Can someone please explain these terms to me? From what I understand, these are simply the LEVELs that a particular piece of gear is optimized to perform at (+4 dBu being at a much louder signal level than -10 dBV <- Is this correct?) .
