Portable, convenient, and packed with power and effects!

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.

  • One could do better for about the same money

    As reviewed by Slant 6 on 5/12/2011

    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.

  • handy and practical

    As reviewed by Charles K. Hartman on 12/10/2010

    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.

  • Great Product

    As reviewed by Digital Djs on 10/22/2009

    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!
