ALC = Automatic Level Control
Esclusivo circuito controllato da microprocessore. Analizza e corregge, in modo continuo, variazioni di ampiezza del segnale di ingresso (50÷600mV) mantenendo costante il livello di amplificazione impostato.
ELS = Electronic Loop Separator
Sofisticato circuito con ingresso differenziale, elimina i disturbi derivanti da connessioni non ideali di GND.

Mi crea un problema di traduzione:
Audio Pre Out
rms
TDH
Vanno tradotte queste lettere? e se si, come ? (a cosa corrispondono?)

Grazie in anticipo per l'aiuto prezioso!

tu trouves tous ces sigles dans les sites de matériel stéréo etc.
Incapable de te dire ce que ça signifie, à part RMS...

RMS: Root Mean Square : valeur efficace d'une tension en Volts ou de la puissance d'un ampli (exprimée en Watts). Il ya une différence entre la puissance « instantanée » d'un amplificateur et sa puissance efficace car une partie de la puissance de l'amplificateur est dissipée sous forme de chaleur. ...

Peer comments on this answer (and responses from the answerer)
agree  Alfredo Tutino: pre OUT è l'uscita del preamplificatore, che fornisce 350 milliVolt RMS (una volta si preferiva scrivere in maiuscolo) e può servire p.e. per registrare; meglio verficare TDH con il cliente: dovrebbe essere un errore per THD - Total Harmonic Distortion
