Shure X2u Reviews

Works as specified

I'll use this with an Audio-Technica wireless system to do a live streaming event at a high school reunion. Needed something that would provide a higher-quality audio source than the microphone in my DSLR, through my laptop and the Magewell USB Capture HDMI card into OBS Studio. You can also place a mixer ahead of this adapter, as it can accommodate a line level source with its volume control, so you can connect just about any audio source to it. Haven't detected any ADC noise so far. Very useful tool for the price.

good sound and simple setup

I bought this to simplify my mic setup for meetings. I was using my Zoom H6 as a XLR-to-USB interface but got tired of having to set it up every time I wanted to use it. This powers on with the USB bus and is ready to go right away. I cannot use the headphone jack, unfortunately, because this is plugged into the back of a microphone base and the headphone jack faces down to my desk. Other than that, this is working perfectly and the sound seems better than through the H6.

Highly recommend

The X2u Ain't Messing Around

Out of all the audio interfaces that you plug into the mic, the Shrue X2u is the best. It's built from the same material that was used to forge Thor's Hammer and not only can it take a beating, it's capable of delivering one too (in the case of self-defense). Also, unlike it's cheaper wannabe competitors, the sound on this is CLEAN and with minimal noise. Finally, its rectangular shape makes sure it doesn't roll of the table (though even if it fell, I doubt this tanky monster would even feel it). Highly recommended and worth the price. You get what you pay for, so pay for greatness and get the Shure X2u.

Penetrates Your Mic From Behind to Make You Happy

If you're looking for an ultra-portable audio interface that you can passionately jam into any XLR mic's behind to practice/record anywhere, anytime, this thing is it. It's the King, the Queen, the Godzilla, the best of the best. If you want quality, forget any other similar looking devices like Pyle, Polsen. Heck, even the similar looking device from MXL (which is decent) can't compare to this in the end. This thang is built like a premium Optimus Prime tank. Drop it and your floor will probably break before this does. Unlike its cheaper competitors, the sound quality is CLEAN and not noisy. Another thing I love is that it's rectangular, so it doesn't roll of your desk like them other circular-looking competitors. To conclude, yes this is pricey compared to its competitors, but that's because it's quality is an absolute 10/10. Highly recommended.

Flawless plug and play

Wanted to start content creation on my mac with an XLR microphone. The x2u was immediately recognized as a mic, no config needed. It came packaged (too) securely. It's built solid, which may be a concern if you're using a cheaper mic arm that cant take the extra weight. Headphone jack on the side is actually way more convenient than the back of my computer! Only wish the gain dial had levels marked on it so I could keep it consistent between adjustments.

I got this audio interface to pair with the Rode Podcaster mic so I could use it for zoom meetings. Listening back to the audio interface, even with the mic gain lowered all the way and the microphone unplugged, there's just a completely audible noise level that's very obvious, no matter which computer or USB port I use. I thought I just had a bad copy, so I RMA'd it and got a replacement, but I still have the issue in the new copy. In contrast, using a Zoom F6 in the same USB ports gives me an inky, inaudible noise floor. If you're using a really hot microphone, this could work because you could set the mic gain low and lower the gain on your computer to suppress the noise, but honestly I just don't think this has good preamps, despite what a lot of the reviews said.

Can this be used to import other instruments ...

Can this be used to import other instruments using a male XLR to female 1/4" adapter, or is this for microphone use only?
Asked by: Thomas
I think it is for microphone use only. I think you would want to use a 'direct box' between the instrument and the x2u. I have never tried this myself.

Does it works normally with a BLX wireless system?
Asked by: Ricardo M.
This provides phantom power to a mic. If you have an output from the wireless receiver that acts as a mic output, then it should work to convert that signal to digital and input it to a computer via USB. It will give you a gain control for the mic and a headphone out with volume control. Check the specs for what you need. This does 48khz at 16bit. That's great, but it is not 24bit, not 96khz. The headphone out also can include sound from the computer mixed in, so it may have some features you don't want just for bringing your wireless signal into the computer. But it is wonderfully small and the durability of this device is top notch.

Can the SM 57 microphone plug directly into my Canon HF 100 HD video camera with a 1/8 (3.5MM) cable?
Asked by: Bob K.
The Shure SM57 can be connected to the 3.5mm input of a camera. For the best sound, it is recommended to use a combination of XLR cable, and specially designed XLR to 3.5mm adapter. The Kopul LMT100 will match the low impedance output of the mic to the high impedance input of the camera. <a href= target= _blank ></a>
