L'Altec 1567A est un mixeur 4 canaux \u00e0 lampes, mono, fabriqu\u00e9 au d\u00e9but des ann\u00e9es 60.<\/span><\/p>\n

Il dispose \u00e0 l'origine de 4 pr\u00e9amplis micros (MIX 1 \u00e0 4), avec entr\u00e9e sur le c\u00e9l\u00e8bre transformateur Peerless 4722, ainsi qu'une entr\u00e9e ligne (MIX 5), et une seule sortie, sur transformateur Peerless 15095.<\/span><\/p>\n

Les 4 pr\u00e9amplis sont de grande qualit\u00e9, avec beaucoup de gain et une \u00e9paisseur de son propre aux (bons) circuits \u00e0 lampes. Mais la sortie mono en rend l'utilisation limit\u00e9e avec le mat\u00e9riel moderne en obligeant \u00e0 n'utiliser qu'une tranche. <\/span><\/p>\n

Cette extension reprend le circuit de sortie, quadrupl\u00e9, avec une attention toute particuli\u00e8re au c\u00e2blage en vrai point \u00e0 point, lampes NOS, et transformateurs Peerless originaux. Elle permet ainsi de pouvoir utiliser s\u00e9par\u00e9ment les 4 pr\u00e9amplis micros pour alimenter 4 tranches de<\/span> carte son. Et chaque tranche est d\u00e9brayable pour conserver le fonctionnement initial du 1567A.<\/span><\/p>\n<\/div>\n<\/div><\/div><\/div><\/div>
