+4 db

dBu, dBm, dBfs, dBVU... Read . Rail

No. It's a voltage thing... a way of rating the input or output. If the outputs are rated as "+4dBu" then zero on an analog-style meter for that equipment is what will produce +4dBu, or "nominal output". If you plug a "+4" output into a "+4" input on another piece of equipment, in general, zero on the meters should read the same. "-10dBV" is the other type of line input/output. It would be less confusing if we just called them something else, like "pro" and "consumer". The important thing is to just make sure that you connect +4 outs to +4 ins, and -10 outs to -10 ins. Here's another way to put it: Say you have a mixing board. When the meters read zero, any of the +4 outputs on the mixer are putting out "zero", and so are the -10 outs. Again, only if you are connecting these outputs to the same rated inputs of another piece of gear. But if you plug a +4 out into a -10 in, it'll be ~ +14dB too hot. A -10 out to a +4 in will be down -14dB. That's why they make +4 to -10 converter boxes.

they say +4 is pro and -10 is semi pro or (consumer) i guess.

Aloha, I think +4 dBu is 11.8 dB greater than -10 dBV... +4 dBu is not referenced to the same level as -10 dBV. You need to read about a gazillion articles on this topic before you can understand it...at least I had too...

EHAuehU funny post... Not Your question man.. The replies... HEHEE Have a good one..
