## Description

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

Review: Sufficient for accurate home studio switching - This week I wanted to AB 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.
Review: A very flexible (and needed) device for switching/selecting different XLR components - 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!

## 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: Can this be used for a speaker selector (ie xlr out of mixer to: (a) pair of studio monitors or (b) pair of powered pa speakers?**
A: Hello. We don't recommend using it to connect speakers directly. The cable can only handle around 50W power. It may not be enough.

**Q: I have 2 pair of "active" or amplified speakers. I have a digital audio interface with line level balanced outs. Will this unit support this setup?**
A: Yes. I’m running Uaudio x8p analogue out to Nobsound 1 in 3 out to power 2 pairs Genelec active monitors. Works well so far.

**Q: What is the difference between this and the one with i/o on both sides with asin b07875kc4f ?**
A: One has three inputs. The selected input outputs to the one and only output. The other has one and only one input and is switched to one of three outputs.

### ⭐⭐⭐⭐ Nice switcher, but not transparent
*by C***E on June 28, 2023*

This is a well built unit. The case is made of aluminum and the knob and jacks are good quality. Yes, it is very light and will tip back with the weight of the cables unless you support them. The 1 in 3 out switcher is not completely transparent, unfortunately, which is why I am knocking off a star. When the switcher is in line between a preamp and an amplifier, music sounds slightly different and not in a positive or enhanced sort of way. Every so slightly dulled and less lively. It's *very* slight, but definitely there. I did a blind test with a friend, using the same 16 gauge high quality XLR cable for both input and output. Every time the switcher was in line, we called that listening session out as being less pleasant to listen to than if the preamp was hooked up to the amplifier directly. Great switch box for the money. However, if you want to use it to switch between powered monitors for critical listening, or to choose between different amps in a hi-fi system you should look elsewhere.
