The durable, lightweight Yamaha EMX312SC 12-Channel Powered Mixer has dual 300W amps, 16 Yamaha SPX effects, built-in graphic EQs, and loads of input options.

Flexible power
The power mode switch lets you use the dual power channels as a stereo amplifier or use one channel for the main speakers and one for the monitors, with separate monitor mix setup via the channel Monitor controls.

SPX digital effects
16 Yamaha SPX effects--including reverb, echo, chorus, flanger, phaser, and even distortion--let you add the finishing touches to your live presentation.

Graphic EQs
Graphic equalizers are provided for both the main and monitor power channels so you can effectively control feedback or tailor the sound to match the room and program material.

Input options
The Yamaha EMX312SC offers a total of 12 input channels--4 for monaural microphone (with phantom power) or line input, plus 4 pairs that can function either as monaural mic inputs or stereo line inputs--providing a versatile mix of input capabilities for a wide range of applications. If only mic inputs are needed, you can use up to 8 mic channels. If you want to play recorded background music during breaks using a stereo input and have a keyboard player with stereo outputs, you still have 6 mic/line inputs available. If all 4 stereo pairs are used to handle stereo line sources, you still have 4 channels available for mono mic or line input. It's a versatile system that can adapt to your needs with ease.

FCL (Feedback Channel Locator) system
The Yamaha FCL (Feedback Channel Locating) system makes locating and eliminating feedback easier than ever. FCL indicators provided on each input channel indicate which channel feedback is occurring in, so you can identify it visually and adjust levels or EQ as required. Another handy features is a Standby switch that mutes channels 1 through 8 so that, for example, after rehearsal or between sets you can mute performer's inputs 1 through 8 without having to change fader settings, while stereo inputs 9 through 12 remain active for background music playback.

Yamaha Speaker Processing
Yamaha Speaker Processing (YSP) provides optimized matching with speakers, for clean, solid reproduction that will deliver your music with maximum impact.

Durable, lightweight design
At only 22 pounds and equipped with conveniently located handles, the EMX312S is easy to transport. It's built to withstand the rigors of the road and deliver reliable performance, night after night.

handy and practical

By Charles K. Hartman

from Seekonk, MA

I bought this powered mixer to replace an old Soundcraft item. Our band (4-5 people) had used one of these for a couple of years with great success indoors and out. At this price point it offers plenty of power, low carrying weight and lots of practical features. It is easily deployed when at the venue and accommodates voices, keys and DI'ed instruments in various arrays. The feedback locater is a nice feature. That it has plenty of power for both mains and monitors is beneficial to a small band like ours. Yamaha quality is another plus. I play in three different small ensembles and often do events for our congregation. This is a versatile, handy and practical piece of equipment.

Do Not Regret Buying It

By Ernesto with Serano Entertainment

from Reno,NV

Now that I have about 12 yrs of mobile music experience I wish I could have started off with one of these. You get: a mixer, amp, effects, all connected together in one light case and lots of mic inputs for singers. I love the way you can separate the amp into two smaller ones to provide a main and monitor amp with separate EQ. I do a summer karaoke venue at an outdoor amphitheater which seats 300 and use 2 12" two-way spks for mains and 2 more for monitors from the top of the amphitheater angled down to the stage (with long cable runs)and it does the job. The only thing I recommend is to buy a small fan and secured it to the side vent of the amp to help cool it on an outdoor summer gig and even then have the unit in some shade. I push this amp at high volume and the sound is clear and the mic levels good. I will be selling my back up rack space amp in the future to buy another one of these. I went to WalMart & bought a rolling carry bag with a lot of outside pockets which I stuffed with padding to carry this mixer in and protect it.

Halfway to Heaven...

By No Clue

from Youngstown, Ohio

This mixer is truly great for any pro or semi-pro band. We don't mic Bass or drums (sometimes a single mic in front of bass drum is neccasarry) and no longer mic guitars, as we have monster combo amps now. We run 3 vocals and like I previously said, some drums, with no problem. The clearity is phenominal. We run through a set of Peavy 115s on 4 1/12 foot poles and our message gets across. The effects are a nice touch, however I rarely ever use more then the multiple "reverb" settings due to the fact we run vocals. I definately recamend. Can get vocals through a school gym, small clubs, outdoors and even an auditorium. NOTE: If you plan on running anything more then vocals I reccemend the 512 through Peavy 215s. Trust me on this. We originally pushed our limiters quite a bit when we used to mic our smaller amps. If youneedto run alot of instrument type stuff go with the EMX 512. It's the same set up only more wattage. Beleive it or not you can blow speakers more by UNDERpowering then OVERpowering. Other then that for our uses it's fantastic. Also note: Unless you run into a powered monnitor you can have major problems. As a result we don't use a monitor currently. Do look into before purchase. Thanks

Great Product

By Digital Djs

from Massillon, Ohio

We bought this almost 2 years ago. We pair it up with a set of Peavey PR15. It works great for a lot of the local bars we work at. Sometimes we hook it up to a set of Yamaha SV115. You will no be disappointed in it's performance. We ar looking into the 512 now!

Its better than I thought it would be

By Steve

from Chino

I bought this mixer hoping to give me a little kick, and then got worried that I wouldnt be able to drive bigger speakers. What a underestimate of power. The minute I hooked it up to some Peavy 115's, it drove them without a problem. In fact if playing in the Garage we can only turn the volume up half way. We play Classic Rock and like it loud and the EMX312 does what we need for now. I would purchase again in a heartbeat.

little giant

By pablo, proaudiosistem

from maracay, Venezuela

first time when i bought one of those little things, i was surprissed about the lightweight and i had some concern if this couldn̴��t make the job... once i hooked my Yamaha S115 i was amazed by the sound it has... clear and powerful for this size, better yet when i used in main-monitor configuration, i put 2 yamaha S115 for the mains and a pair of yamaha A12m stage monitor, and the mixer did the job whit no problem, I recomend this mixer for small-medium rooms, even in small venues, It will surprise you...

Great for your church

By P. Virtue

from NY

We are using this mixer in a church sanctuary that is about 100 x 50 with 12 foot flat ceilings. We had the 512 originally before it got stolen this year. We decided to buy this 312 to replace it and it still pumps out the power through two br-15 yamaha speakers. Only thing to watch out for. Had the same problem with the 512. When you hook up a cd recorder to the cd record outs the signal is very low and the record quality is so low you can barely hear it. We ended up running the record out of the Monitor output on the mixer and that seems to have alot more power output. Overall a great product.

not the best

By steve

from florida

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.
