Salut amis two rock
Je viens de lire ça dans la section faq du site two rock à propos du câblage des cabs. Quelqu'un peut m'aider? J'avoue ne rien piger... Moi blonde !!
Care needs to be taken when installing new speakers or adding other manufactures cabinets to our amps. All of our amps that have reverb have a reverse phased output section. What this means is that the signal is in the negative swing as it leaves the amplifier. Traditional wiring of speakers takes the “+” positive terminal and connects it to the tip of the speaker jack, and the “-“ negative terminal and connects it to the sleeve of the speaker jack. When the speaker gets the signal in this configuration the speaker will push first and the pull. If the wiring of the cabinet is “Out of Phase” with the amp then the speaker will pull first and then push. We wire all our cabinets and combos that pair with our reverb amps with the “-“ speaker terminal going to the tip of the speaker jack and the “+” positive going to the sleeve. This way the signal that is in the negative swing as it leaves the amp see a negative polarity at the speaker. Causing it to push first and then pull. Making sure that the amplifier matches the cabinet will result in the amp/speakers working together. This will increase the dynamic range and tone of the system. It will not hurt the amp to have the speaker running in an opposite polarity then the amp. It will just sound slightly muffled and not have the headroom. Amplifiers that have no reverb will want to be wired in the traditional manner.
Merci de votre aide.
Alors, j'ai fait un nouveau câble HP ce soir: même référence de câble, même longueur.
Ça change effectivement pas mal la donne (j'ai un Port City 2x12 en Creamback G12M65):
- Le spectre semble plus large, en haut comme en bas.
- Le médiums est plus riche
- La magnifique reverb est bien mise en valeur.
- Il me semble que le son est plus droit, moins creusé dans les médiums.
Dans l'ensemble, c'est pas simple à expliquer.
J'ai pas pu tester à haut volume.
A bon entendeur!
