+21 dBu max on input would be something you would see at line level, not mic level. Mic level signals never get that hot. So I assume the wanted to say “+21dBu on output”.

thekid777 said:Hi John, so I should look at my converters output impedance which feed the console then
and be sure it is 600 ohms, make sense!
It seems dBu was invented by Allan Hurst who worked with R.Neve back in the days.
Here's a quote from him:
"I invented the dBu term - measuring volts . 0dBu = 0.775V rms, whatever the impedance. Previously the industry used 0dBm where 0.775V is 1mW but only if dissipated in 600 ohms. In practice the various impedances in an audio chain vary enormously, so 1mW is a different voltage depending on the impedance. Confusing. My idea is much easier to interpret."
thekid777 said:Hmm, my idea was too be sure what maximum level out of my converter I could put into the console.
