This is a fairly thorough walkthrough of all the features of the Behringer Xenyx 302USB Mixer.

Things to Know

This is a USB mixer meaning you can hook it up to your computer. HOWEVER, it does not provide the option to record audio to separate tracks at the same time. All audio going through the mixer is sent to the computer as a SINGLE audio track.
This mixer provides Phantom Power to your microphone, however, I was unable to find a switch, so I assume it is always on. Therefore, I want to include the disclaimer BE CAREFUL IF YOU'RE USING A RIBBON MIC WITH THIS!

Performance / Featrures

The first thing that I really like about this mixer is that it provides latency free monitoring. It has a single XLR input with a 2 band eq and pan fader. It also has preamp gain and mic volume. I did notice that there was a bit of noise when I got the preamp above 50%.

The second channel consists of 2 options. 1) RCA Line in or 2) USB Input. The first option is fairly self explanatory, but with the click of the red button, the second one allows you to hear your computer is playing. Directly next to the red button, this option allows you to send channel 2's audio to the mix, or just to your headphones. This is perfect for recording. If you are recording vocals or guitar in a DAW, you just want your previously recorded tracks to go just to your headphones, you don't want that stuff re-recorded onto every track.

In the upper right hand side of the mixer are (2) 3.5mm jacks. One is for your headphones, and the other is for a microphone input. If you have a gaming headset that splits into (2) 3.5mm jacks, this will work. I do want to know that, this microphone input is controlled by the channel one faders & knobs. Therefore, I would only recommend using one or the other.

Lastly, it has an RCA main mix output, so you can send the audio to an amplifier and hear your mix/recording on bigger speakers.

Conclusion

I think this is a pretty cool little device. I wish I had it when I was just getting into recording. It sounds good. It makes recording very easy, and it provides more control over your sound than if you were to just plug into a USB audio adapter (like I do for all my videos). The one main issue I have with this device is that it is not easy to expand from. Basically, it's a great starters unit, but if you have a few extra bucks, I would recommend springing a more powerful version like the Q802USB or Q1202USB. These more powerful versions will provide you more room to expand and you won't have to upgrade too much.

If you have any questions about this Mixer, leave them in the comments down below or on youtube and I'll try to get to them ASAP. Thanks for reading & watching.
