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

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.

Very happy with this for the price and quality. You can also configure it backwards for 1-IN-3-OUT per the manual.

Solves routing problems easily. Conveniently small and unobtrusive. Unique tool and this company makes the opposite. 1 in and three out. I’ve used twice so far on gigs. It is exactly what I needed and well manufactured. Contemplating buying the 1 in 3 out version too.

No frills, works decently

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.

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.

After upgrading a pair of powered studio monitors (Dynaudio BM5A) which only have balanced XLR inputs (which are better than RCA ports, which are unbalanced), I wanted to connect multiple sources to them but couldn't find any solution. There are many options that provide a single source connected to multiple monitors, but not multiple sources to a single set of monitors -- until I finally found this device. I now have it connected to a Pioneer FM tuner, an OPPO disk player, and a Logitech Bluetooth receiver (I used RCA to XLR cables for the tuner and the Bluetooth receiver, and Mogami XLR cables that I already had for the disk player). Selecting the different sources is very simple, and the sound quality is very good (although I use this system only for background music, so I confess haven't listened to it very closely). In short, this is a great tool for my need. At minimum, if you think it might be a good choice for you, it's worth a try -- you can always return it within 30 days if it's not as good as you had hoped.

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.

Bought to switch between two separate mixing desks at our small theatre. One is a small simple mixing desk used by outside groups, the other a larger more complicated digital mixing desk. I'm really pleased with it and there is no discernible cross talk/grounding issues. It silently switches and does exactly what we needed it to do. It could also be used to switch between different active speakers or anything with XLR connectors.

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!

Très bon produit
