Behringer Xenyx 802 Premium 8-Input 2-Bus Mixer with Xenyx Mic Preamps and British EQs

The Behringer Xenyx 802 is a very nice control board for the price. It came promptly, and included a very nice manual in several languages. I had enough background knowledge to use this product out of the box, but for somebody who didn't, the manual could very easily explain it to them quickly and have them mixing in no time. The only real thing I noticed quickly is that the light signifying that it is on is obnoxiously bright, to the point where it is distracting. This was an easy fix, I taped a little piece of lighting gel over it and got it to a point where I liked it. I played with the mixing functions a little bit using several techniques and my results are recorded below:

The first test of this unit was simply trying it out with a few different medium quality speakers and seeing how it sounded. I attached an Mp3 player for input and hooked up several bases for output. Most of the controls worked flawlessly, the board didn't seem to be broken in any way. Distortion was pretty high, I messed with the gain a bit, and played with the various volumes and EQs until I got it how I liked. This would have been a bigger problem if I had been somebody whom had never operated a mixer before, it would've taken a lot longer to fix this using only the manual. The EQs worked nicely, the middle functioned particularly well, bass caused some distortion but nothing annoying; however, treble wasn't excellent, it made the high frequency audio sound a tad metallic and cut off some at the top.

My second test was also with an Mp3 player as input, but this time I used several different types of headphones as output. Distortion was higher this time, and with some songs I could not completely eliminate it. That said, the control room function worked nicely with a little less distortion, and I'm not quite sure why I would want headphones on one of the mains. The EQs did little to eliminate this distortion, as did the gain, but I could limit it using the various volumes.

My third test involved using the mixer as if it were mixing for an actual band. I had a Shure Sm58 wired on input 1, a Crown "Floor Mic" on input 2, a bass guitar and (cheap) electric guitar on input 3/4 , and a keyboard on input 5/6. The whole 3/4 and 5/6 inputs bugged me, as it really shouldn't have been considered 6 input. I ended up plugging the guitars and keyboards into the double amps because the doubles didn't have XLR which the microphones needed. That said, phantom power worked like a charm and the floor mic worked nicely. Distortion was considerably lower with my voice as the input, and I was unable to hit any notes high enough to sound bad (well...bad in comparison to my normal voice.) The Bass/guitar match up worked nicely, as the bass EQ barely affected the guitar and the treble EQ affected the bass. This allowed me some level of individuality, but not as much as I would have liked. Distortion was higher in both of the actual instruments in comparison to the microphones, but not in comparison to the mp3 players. This pleased me a little bit, but the lack of individual controls makes me wonder whether setting up this board to run a band would be a good idea.

My final test involved plugging it in to a full audio system in a real venue, and seeing how it sounded there. I tried out several different inputs and outputs, including but not limited to floor mics, sm58s (wired and otherwise), sm57s, a computer, and an mp3 player. The problems were approximately the same; however, with high power amplifiers I didn't need to use the amplification included in the board at all. Doing this, distortion was cut out almost completely.
