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

## Questions & Answers

**Q: In xlr input - rca output setup, does it invert and sum up negative with positive signal(removing noise), and then only pass to rca?**
A: Using XLR at both ends gives a better sound, if using XLR at one end and the other end is RCA, the sound output will slightly lower down and need to increase the volume and there will be no sound distortion.

**Q: When output "A" is selected, are outputs "B" and "C" left floating or are they grounded, etc?**
A: Well this is a 3 IN 1 OUT switch. So only one out. As for the other inputs being grounded when not selected, I can’t answer that, but there is no noise from other inputs.

**Q: Does anyone know of a similar switch that supports an infrared remote control to select the input, as opposed to only the physical selector dial ?**
A: No. Have not scene one.

**Q: Balanced inputs without balanced internals?
one customer review claims as much, which defeats the purpose of using xlr cables. is this true?**
A: Hello. It is balanced in and out. This device won't change any characteristics. It is only a passive converter.

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.
