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

But...the Large knob which is the centerpiece of the unit is kind of plasticky-feeling and somewhat slippery; but not a deal breaker. The unit works well and does what it is supposed to deo, without electrical interference/noise. Solid housing as well. Good xlr connections.Recommended.

This week I wanted to A<=>B compare two power amplifiers fed alternately by a single DAC, hence the need for this 1-in-3 output selector for a single source. I am quite happy with the 3-in-1 output version of this device, which I used last year to compare several DACs fed to the same power amplifier. So it was a no-brainer to purchase this 1-in-3 output version this time around.These boxes are not full-on professional products. Such pro products would sport famous name parts, all metal construction, withstand rough handling, be rack-mountable, etc., and would cost far more. These Nobsound boxes use good parts and are well made in plastic and metal. In normal listening, I've never detected a degradation in the audio signal caused by these boxes.

I've been using the one little bear for about a week now to switch between two separate sets of studio monitors from my DAC. I think I have a very discerning ear and there is no sound coloration when using this switcher (which I was a bit afraid of before ordering). Switching is seamless with no audible "pops" when switching between both sets of speakers which is a huge plus for anyone who monitors loudly. The XLR connection points are pretty good with just a slight amount of wiggle. The box itself is made well and is made of fully enclosed metal. The box is indeed very light, but I haven't experienced any of the cabling pulling the box off of it's feet. The feel of the front dial is good (if that is important to you), however with my unit the dial is slightly off-centered so when I switch to the "Y" setting the dash indicator on the dial doesn't exactly line up with the "Y" lettering.As far as functionality is concerned, this is a 5 star unit. For QC purposes it gets 4 stars. But it's a solid box with only one or two competitors in the market for XLR connections so there aren't a lot of choices out there. This was a good choice though.

I purchased this item because I run multiple balanced headphones amps, both solid state and tube/valves. Depending on what I'm listing to and what headphones im using I had to manually switch my xlr cables from one device to the other. This became cumbersome and i worried that plugging in and removing the cables i might damage the cables or worse my amplifiers. This 3 way switcher is absolutely perfect for my needs, now I just have to turn the knob to the amp that I want. I never have to plug/unplug my cables again. Just make sure that you pay close attention to the product description because there are 2 different types. This is 1 in 3 out which is what I personally need for my setup, the other is 3 in 1 out the way it connect is different they both look the same from the front. The only way to tell is to look at the back and read the description closely. I know that this is supposed to just be a pass thru switcher, but i swear that the sound is louder than before, could be my mind playing tricks on me but to me it sounds loader. There is no added noise or static that i can hear just clean sound as it should be. Im glad i purchased this unit, very happy.

Let's face it, once you get into the "balanced" craze of using just balanced input devices, you soon realize that you wish you had one of these switchers. I'm using purely balanced power amplifiers now, along with a few balanced DAC units, and I got tired of having to first get up and pull out cables, then plugging them back into another device.This Nobsound XLR switcher is reasonably priced, and you can use it either way - that is, you can set it up to use one device going in and switching them between 3 different other devices (like amplifiers), or you can have 3 devices going in, and switch between them to one device going out.Additionally, this is a fantastic price for such a switcher, and you will certainly appreciate having one. I do wish I could find an XLR switcher that had the ability to connect 4 or 5 devices, but heck, those are impossible to find unless you have one custom-built.Sound-wise, I could hear no differences or audio drop-outs at all. The same quality balanced audio is maintained when you switch between devices. In my particular setup, I have one DAC connected to the one input, and I have 3 different balanced power amplifiers attached to the other end. This way I can compare and A/B several different amps to evaluate sound differences.So if you're into balanced audio devices, this is one device that you will need and once you get one, you will wonder why you hadn't acquired one previously.Highly recommended!

I use this XLR switch with my Ham Radios to use one microphone with 3 radios. Works well so far...and it's metal case is good for shielding in a high power radio environment.

This device is nice but unfortunately it misses the mark. They need to add more weight to the base. Once XLR cables are plugged in it tilts backwards and looks horrible. Also turning the knob shows how light the switch is also. Sure you could rig it yourself but I just returned it and will look for a more quality solution
