I bought a EMX312SC four years ago for use with an odd confederation of musicians who put on episodic jams at a local pub. The onstage line up is ever changing as people flow in and out out every configuration from solo to quintet to a "if you've got it, bring it on up" house jam. I thought that a powered mixer would keep things simple while giving me the flexibility I needed to produce a show of this sort, but I was wrong. My complaints include the following: 1The microphone preamps are of poor quality. I made a significant improvement in the sound early on by running everything into the power amp section of the Yamaha via an outboard mixer. 2)The SPX effects are about as cheesy as one would expect, and the effects bleed into other channels at time even when the effects knobs are at 0. 3)The feedback control locater feature are more distracting and alarming than helpful. The lights on any channel carrying heavy transients flash constantly, and at times even the mic or even unused channels light up 4)The whole unit seemed to lead to more feedback problems than I have had since going to separates. Positives include: 1)The power amp seems quite decent, considering. It is stable and reliable, and rarely clips even when driven hard. The sound is excellent when one eschews the onboard preamps and uses a good outboard mixer. 2)The speaker processing feature works surprisingly well, as does the graphic equalizer. 3)The ability to split the power section into main and monitor output is a really nice feature. One can run two 8 ohm mains and two 8 ohm monitors and get nice sound levels for both the audience and the performers. 4)The 312 works beautifully when dedicated to our drummer's Roland V set. He runs a Yamaha BR15 on the main channel and a BR12M on the monitor channel. The YSP feature contributes to some real lower end punch without phony boominess, and a bit of reverb lends a real sense of depth to the e drum sound. In conclusion, the 312 might be fine for relatively simple acts, and it works wonderfully well with the Roland V drumse;, however, the mediocre quality of the preamps is a significantly limiting factor. I'd recommend spending just a bit more on separates. One could buy a small Mackie mixer and a 200 or 300wt/ch QSC or Crown amp for about the same money and come out way ahead.
Very well built. I purchased one a few days ago and it has been amazing. I sing in a rock band and it pushes over the drums so well. Its clarity is quite phenomenal. I completely suggest this.
ive been using this for a while now and not really impressed. hard to dial in with a band. clips easily even low volumes. you can get it to sound great but its a chore doing so. the effects are good but not very strong so dont expect your dely's to stand out front either. you'll see if you get this. i hate this mixer. solo acts, it works fine. but i want something else. this thing sucks for band use.
