Il tecnico mi ha risposto correttamente ?
Inviato: 7 set 2012, 11:32Ho collegato in loopback sulla mia scheda audio (RME Fireface 800) OUT 1 e IN 1, l'uscita (OUT 1) pilota correttamente il segnale, (è un segnale di una sinusoide da 1kHz @ -1db), in entrata (IN 1) però mi ritrovo -1.53dB anzichè l'atteso -1.0 dB, ho chiesto spiegazioni sul forum RME, un loro tecnico mi ha risposto in questa maniera :
---
Because both input and output stages have a small intentional offset to prevent overload. If in your example both levels would be set to match 100%, and the usual deviation during manufacturing causes a positive offset of only 0.1 dB, you would get overloads already. So better loose a little bit and stay on the safe side.
