Standard for audio levels? () on lines
Frage von stonee:
I have in vain for information on the network audio level s.Chinch searched and XLR connectors.
For video it's quite simple: 0 dB are here 1Vss s.75 ohms or without the sync pulse 0.7 V s.75 ohms.
What about the sound? What voltage s.welchem resistance here correspond to 0 dB?
Ps: The sound pressure level does not interest me. I am only interested in the level on the lines.
Antwort von marmor78:
The normal level of 0 dB is 0.775 V RMS (at 600 Ohm conclusion, I think)
The ARD studio level is +6 dB according to 1,55 Volt, dH for devices from Ö.R. Radio will come out at full scale (0dB) 1.55 volts.
In live sound reinforcement stage is often worked with +4 dB.
Finally, there are mainly in old home HiFi (such devices with DIN connector) an output level of -10 dB (0.32 volts)
