Nobsound 3-IN-1-OUT XLR Audio Switch ; Balanced Audio Converter ; 3-Way Stereo Passive Audio Selector Switcher (MC103 Pro 3-in)

This is the perfect device for what was needed. It has been tested, and all three sets of inputs and the one set of outputs work as intended. Good design, good implementation. Sound coming out is completely transparent, as it should be. The form factor is just right, even if the cables do pull the device backward. The alternative of putting inputs and outputs on multiple sides has its own set of drawbacks, and I prefer this configuration. I have read detailed analyses that confirm what my ears tell me. No signal coloration and indiscernible crosstalk. The latter issue (crosstalk) has not been tested extensively in current setup, but I don't hear a thing. Downside: Amazon. It was clear to me as soon as I opened the device that it had been ... opened previously. Pretty sure this was a used device. There is a big Amazon sticker on the outside of the box and the item had been removed from its bag, inside. In addition, the box had an 'impact' indentation on one corner. Does any of this affect usage? Not that I can see. Time will tell. But what is clearly not right is charging full price when an item has been previously used. I'd love for Amazon to chime in and prove me wrong here. But all evidence points to being sold a used item, at new price. And that does not leave me a happy Amazon customer. Things are going the wrong direction, and long time customers notice.

Used for swapping between AV reveiver pre amp out and DAC streamer. Used in recording studio for A/B testing of streaming DACs. Performed as needed. No distortion added to signals. Also tested by audio engineer. Thumbs up. Recommended

Using the box to switch between two sets of XLR connectors to a headphone amplifier. Works great. Can't hear the sound being affected. Excellent value for money. Delivery faster than promised.

Some images of this product appear on the internet showing "Neutrik" XLR connectors. Note that this product offering does not claim Neutrik connectors. The unit I received sported only generic XLR's. If Neutriks had been utilized, the end product price would be a lot more than currently offered. Having clarified that, the components and assembly of this XLR switch are basic, but it will work fine in audiophile or even professional environments for casual, light duty applications. I used it for an A-B test of a new DAC vs. my previously utilized DAC. I felt there was some audio improvement with the new DAC but wanted to verify that in a matched-level A-B test. The switch box permits auditioning each sound with minimal delay for switching. Since the rotary switch on this box was reported to be the make-before-break type, I used only the "X" and "Z" inputs, so that the two DACs were always completely isolated from each other. Many other reviews, including a technical measurement review on a gear-oriented website, confirm that this box does not alter or detract from the sound. That also was my experience. Having completed my A-B test, this box will be handy to keep around for occasional future need.

We'll made but not rugged. This does what it's supposed to without introducing interference or noise. The case is thin and the device is light but it shouldn't fall apart if you don't abuse it. I use it in my editing suite at home and has been used several times a day to switch between various near field monitors. The switches have held up well and the unit is generally solid. Anchoring it to a work surface will help it's stability. Even just putting a book on top will do that. Overall very pleased with this. A little sad that it's so difficult to find this sort of gear made in the US but such is life. Keep that in mind because shipping can take weeks from China. They originally gave me a lead time of two to three months. Luckily it showed up in just over a month.

This thing is a godsend for home studios. I have a few sets of speakers, but only one with xlr connections through the active subs outputs, and since I don't use a patchbay I needed something to swap xlr inputs from 3 sources: a large format analog mixer, and 2 8 xlr input USB interfaces. As any recording enthusiast knows you want as many options as possible. This is a simple, effective, and affordable piece of gear that allows me to swap connections from 3 sources to one set of speakers.

This little box works exactly as well as you're hoping it does. Audio (and phantom power) passes through it very cleanly, without any distortion, coloration, or signal loss at all. My studio is close to some radio towers (I can hear NPR clearly through some of my guitar pedals), but this device does not seem to be at all susceptible to RFI, which was a huge relief. I tested it between a stereo pair of Neumann KM 184s and an Apollo Twin interface, and it sounded absolutely identical to running the mics directly into the Apollo Twin. The other source I tried (analog synths and a drum machine through a Mackie mixer into the switching box and then into the Apollo Twin) sounded perfect too. In case you're wondering why it looks a little different in my picture, I used gaffer's tape and a Sharpie to make the design even more minimalist.

Excellent Product. I'm using it to run my audio production setup and my hifi/listening setup out to one pair of active monitors. I notice no noise or signal degradation at all in my particular case. My one and only gripe is the weight of the product; it's very light, and if you're using very heavy XLR cables it will tilt backwards slightly, though I'm not deducting any stars for that as it doesn't effect functionality.

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.

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.

Using this for a high end HiFi set up where I need to switch between two sets of XLR’s into a high end headphone amp. My set up is very clear and detailed so was initially concerned about any potential negative impacts but fortunately no issues. So incredibly good value for performance and build quality.

Long story short, I wanted to get this product (and I still do). Trouble is that instead of 3-in-1out, I kept getting 3-out-1in. Not once, not twice, not three times, but FOUR times in a row. Customer Service at Amazon India was empathetic but unhelpful in helping me get the right product. The seller Douk India is unresponsive to messages. There is something broken in the Amazon CS system. But does anybody care to fix it? Nah!
