Regolazione di questa unità

Comando del guadagno

La regolazione dei comandi del guadag- no A e B serve ad adeguare l’uscita dello stereo all’amplificatore Pioneer. Normalmente lasciare controllo l’aumento di totenza sulla posizione “NORMAL” (“normale”). Se l’uscita risulta bassa anche alzando il volume dello stereo, ruotare questi comandi in senso orario. Se si notano distorsioni nel suono quando si alza il volume dello stereo, ruotare i comandi in senso antiorario.

•Se si fa uso di una sola spina di ingresso, disporre i comandi del guadagno per le uscite degli altoparlanti A e B sulla stessa posizione.

•In caso di uso in combinazione con un car stereo dotato di presa di tipo RCA (uscita standard di 500 mV) porre questo coman- do sulla posizione NORMAL. In caso di uso in combinazione con un car stereo dotato di presa di tipo RCA con uscita massima di 4 V, o più, regolare il livello in modo che si adegui al livello di uscita del car stereo.

•In caso di percezione di eccessivo rumore durante l’uso dei terminali di ingresso degli altoparlanti, ruotare il comando del guadagno in senso antiorario.
