G4NSJ – Audio Mixer Teyun A4 Behringer XENYX QX1204USB Shure MV7X Cloudlifter


I wanted a stereo pre-amp for a project and, while looking for bits and pieces on the internet, I came across this audio mixer. I decided that it would be better than a simple pre-amp and, as it was cheap, I thought I might as well give it a try. I have to say that I’m impressed. It only has two mono inputs and one stereo input so it’s nothing special. But it has built-in Bluetooth, a USB port, an MP3 player, a main output plus a recording output… and the sound quality is excellent for the price.

Also, I can plug a memory stick into the USB socket and listen to my music through the MP3 player. As seen in the photo, there are play and pause buttons as well as next or last track. It really is an amazing piece of kit. I’m using the mixer as part of my recording set up for my podcasts. You can listen to my podcasts here.

There’s an echo effect which, although I don’t use, works very well.

Below is my Cloudlifter CL-1. This boosts the signal from the Shure MV7X microphone by up to 25 dB before it enters the mixer.

I’ve now bought a Behringer XENYX mixer, see photo below. I needed something a little more professional so I went for this excellent mixer. I’m trying to get to grips with all the functions, which will take some time, but it’s worth the effort.
