Master ? PPIMV ? Atténuateur ? Son du HP ? Une réponse ici.

Here are some facts to consider when using an attenuator. Attenuators do work. They are not the cause of transformer failures. An attenuator can only simulate two out of the four components that are involved when you crank up an amp. The four components are #1 preamp tube distortion, #2 power tube distortion, #3 speaker distortion and #4 the physical movement of air that your speakers produce at high volumes. So the two components missing are speaker distortion and the physical movement of air and these are huge components! So if you’re playing at moderate volumes and just want to tame the amp down to get a bit of power tube breakup then an attenuator is a great tool, but do not expect to be able to dime your amp and then use any attenuator on the market to get the exact same sound from your amp at whisper quiet volumes. You can't get there from here. You would be better off with a one watt amp.

Merci! Même sans atténuateur, pas de souci que le HP reçoive trop de puissance alors...? Je n'atténue que via le ppimv, on s'est bien compris..?
Pour le volume, impossible d'abuser, même avec le ppimv a mi-course je ne pousse pas le volume: canaux en parallèle avec volume 1 à 1,5 (!) et le 2eme vers 4-4,5!
