OVERVIEW

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.

FEATURES
  • Dual 300W amps
  • Power mode switch allows amps to function in stereo or as separate mono channels for mains and monitors
  • 16 SPX digital effects including reverb, echo, chorus, flanger, phaser, and distortion

  • 3-band EQ per input channel
  • 12 input channels: 4 for monaural microphone with phantom power or line input and 4 pairs that can function either as monaural mic inputs or stereo line inputs

I actually own the EMX512SC, but I am posting here in order to address some erroneous claims made by "Raider Eddie". First of all, you DO NOT need 4 ohm speakers in order to use this mixer properly!The "normal", "semi pro" setup, at least from my experience, would be 2 main/FOH speakers (8 ohms each; 4 when paralleled), along with 2 monitors (also 4 ohms when paralleled). So, in this case, the EMX series mixers are perfectly matched to the speakers.In addition, I have no idea where "Raider Eddie" got his specs, but here are the (RMS) power ratings from the user manual:EMX212S: 130/220 Watts (8/4 ohms)EMX312SC: 190/300 Watts (8/4 ohms)EMX512SC: 350/500 Watts (8/4 ohms)Note that these are not "peak" power ratings, which are used by many of Yamaha's competitors (Mackie, Behringer, etc.). So the EMX mixers are more powerful than other similar products that may appear, at first glance, to be equal in that respect.

I was really disappointed with this unit. I read a lot of good things and my expectations were that it was at least usable. I found the sound to be a little boxy, especially when using the built-in compression. But, that was not the deal breaker. Two things broke the deal for me. One, the FCL (Feedback Channel Locating) lamp lights up at any volume when using a microphone or acoustic guitar with a piezo PU. It even lit up when I was speaking into the mic with the LEVEL for that channel turned all the way down! When I was strumming my guitar on one channel, the FCL lit up for both the microphone and guitar channels! I'm using a dynamic mic (no phantom power), postioned a few feet behind the speaker (I also moved around with the mic to see if it was some acoustical node; not the case). I had the levels for the channels about 1 and the master volume about half (very low volume; not even loud enough for a gig in a small room). There is no trim pot, which suggests that the input is padded dynamically - and doing a very poor job. I'm an engineer who has designed and built my own amps and has studied architectural acoustics, so I can say with confidence that these things should not be happening. Something is clearly wrong. The second deal breaker is the built in echoes. I only use a slap back, so those are the only ones I tried. The Karaoke was better than the vocal echo, but both were unusable. The delay time and repeats are set (you can't tweek them). The delay time is far too long and the effect ends with a few repeats and a medium-long reverb. It might be OK for slow ballards, but nothing else. The unit's compact size and light weight don't trump bad effects or bizarre behavior.

      Comments about Yamaha EMX312SC Powered Mixer:

      Plenty of power to get vocals up over the drum level. We run the keyboard thru it and I mic my amp through it, too. I like the way you can tilt the unit--it makes it easy to see all the controls from the small folding table I sit it on. Good thing, too--the props they provide are kind of cheap and easy to lose (I've lost one already). It's really light compared to my last one, which was about ten years old. The built-in handle is sturdy and makes it easy to carry.
      The only minor complaint is the middle of the scale on all the dials is at 2 o'clock instead of 12. But I'm already used to that.

      Comments about Yamaha EMX312SC Powered Mixer:

      This is a great mixer. My band plays all types of venues. On really small gigs we split the amp and use 1/2 for monitors and 1/2 for mains. For outdoor performances we use the amp for mains, then patch out to another amp for monitors, and a Crown 1500 amp with additional speakers to obtain approx 1500 watts. Two things to know about this amp: 1) to obtain 300w a side you have to run 4 ohms. 2) Without a gain control per channel, when you turn up the volume you are also turning up the gain which might create feedback. Easy to use, convenient, light--great mixer.

      Very good unit. Well made. Typical Yamaha good quality. Might benefit from an extra speaker jack on the output, especially if using it to drive a pair for FOH, and a second pair for monitors.

      Works great for a one-man band!

      By Rodney Rasberry

      from Houston, TX

      Comments about Yamaha EMX312SC Powered Mixer:

      I am an older professional musician and I appreciate this board is so light and and provides quality sound. Hopefully it will give me a long lasting service like all my other Yamaha products.
      Separate main and monitor controls and EQ are outstanding. Compression feature is nice, too.
      Because I use smaller speakers ( 8" & 10") this board is more than adequate. May not be powerful enough for larger venues.
      Worth every penny.

      Small/Medium venue workhorse

      By Pablo Diablo

      from Wisconsin

      Comments about Yamaha EMX312SC Powered Mixer:

      I've been using this "P.A. in a Box" for about two years at a brewpub venue with no technical problems at all. With it's duel 300w channels, half goes to the main sound and half goes to monitors. It will cover up to some extremely loud acts...but without saying, if you're looking to book mostly rock acts, you should find something more powerful. It'd make a good practice P.A. for a rock band though.If you're a small venue like a coffee shop, small bar, this is probably a good pic. As a booking person, I have bands everyday out of the week and I'm not always there. The format of this P.A. is very straight forward, most people who have used a guitar amp or any other soundboard device can learn this P.A. in a minute or two. However, with very loud sound, you will need to know the room and how to deal with feed back, as with any other P.A. out there. I have developed a few tricks to make this thing run about as hot as it can get without feeding back. Some EQ tweaking might be needed...I suggest never pushing the Eq past a couple of clicks/6db over the 0 line, on the graphic eq. Mess around with the knob eqs as needed..I keep them around 0 most of the time, although some individual channel tweaking is needed at times.

      Fantastic for practice spaceQ

      By SherpaK

      from Boston

      Comments about Yamaha EMX312SC Powered Mixer:

      i initially bought this to power my FOH (Yamaha SM112)speakers and cheap Kustom monitors for vocals only. It did a marvelous job. As we grew, and added the Crown amps, Peavey mixer, JBL subs, and Yamaha s115, I decided to keep it as an on stage monitor amp mixer. It performs extremely well for this purpose also. We use it almost exclusively as our practice amp/mixer: it has more than adequate power for that purpose! You can not go wrong with thi unit!
