Review: Je crois que j'avais déjà laissé un commentaire sur ce produit mais comme je viens d'en acheter un deuxième après plusieurs années d'utilisation du premier, j'en profite pour renouveler ma satisfaction. Bien sûr il faut avoir un câblage en symétrique pour lui trouver tout son intérêt, mais si c'est le cas, vous aurez du mal à lui trouver un compétiteur car il est à la fois solide, efficace et durable. J'utilise toujours celui que j'ai acheté en premier et il ne présente aucun défaut. Je rappelle que ce commutateur est purement passif, il n'introduit donc pas de distorsion ni de bruits électroniques, c'est purement parfait.
Review: Item received in good order… Well designed product

Robi to co ma robić. Przełącza sygnał z wielu źródeł. Ja wykorzystuje do niej beluga dwóch zespołów na salce prób. Dwa różne miksery podłączone pod jeden zestaw nagłośnieniowy dzięki temu urządzeniu. Wygląda porządnie. Działa też bez zarzutu.
