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.

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!

This XLR switch worked perfectly at first. But soon it was making a scratching noise when you turned the dial. I took the box apart and sprayed WD-40 on the inner switch workings. Have had no problems with it ever since.

This Nobsound has excellent build quality, is very light, and is quite easy to use!

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 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.

The backplate is either on backward, or something else is going on here, but thank God the QC Pass sticker is on the unit!This is brand new, never used, never had a single cable plugged into it, etc.Not too happy to find this as nothing is arriving on time from Amazon (or anywhere else), and it's unlikely I'll have everything I need to set up my gear over the coming break. Additionally, I don't know if I want to just start plugging cables in or not to this.I've sent a message to the seller and will update this review once they respond. For now, this unit is DOA as far as I'm concerned. How they miss this is beyond me......UPDATE - While at first glance it just looks like the back panel is on upside down, if you look more closely you'll see that the entire board is upside down. You can tell, because the larger gaps between what are supposed to be the inputs (i.e. the two female connections) are on the wrong side of the unit. That means they've managed to assemble it not only with the board and panel upside down, but they've soldered the wrong connectors in the two outside positions.HOW IN THE WORLD DID THEY LET THIS GET THROUGH QC? This is not able to be used like this at all.
