• Integrated Solutions for Superior Live Sound

Experienced musicians, performers, speakers, and club operators know the importance of a high-quality sound system with the right features and performance to deliver their sound. Where portability and convenience are important criteria, a system based on a high-performance Yamaha EMXseries powered mixer is definitely the way to go. In one integrated, portable unit you have a mixer to combine and balance your microphone, instrument, and line sources, effects to refine and polish your sound, and power to drive the main speakers and even monitor speakers as well. But that's nowhere near the whole story - Yamaha EMX-series Powered Mixers offer a range of features that let you mix, process, and deliver your sound with maximum quality and creative control ... and, of course, that unrivalled Yamaha sound.
• Features for Superior Sound and Convenience

Great Yamaha Sound
Yamaha is a leader in the field of professional live sound for a very good reason: we deliver the sound and performance that the pros demand. The EMX-series powered mixers are no exception. They're built at the same standards of sonic performance and rugged reliability that makes Yamaha the first choice for live sound applications from schools to stadiums around the globe.
One-knob Compression on Mono Channels
All four monaural mic/line channels on the EMX512SC feature built-in compressors that can help to bring vocals to the front of the mix, give your guitars extra smoothness and presence, deliver more authoritative bass sound, and generally refine your mixes in a multitude of ways. These one-knob compressors are simple to use, too. There's no need to juggle multiple attack, threshold, makeup gain, and other controls - just set the COMP control for the amount of compression you need.
SPX Digital Effects
Features a selection of 16 top-quality Yamaha SPX effects - including reverb, echo, chorus, flanger, phaser, and even distortion - that can add the final touch to your live presentation. Yamaha SPX digital effects are widely recognized as being some of the finest available, and the effects provided in the EMX mixers live up to that reputation.
Built-in Graphic EQ
Graphic equalizers are provided for both the main and monitor channels, so you can effectively control feedback or tailor the sound to match the room and program material.
Stand-by Mode
When you're done with a set simply engage the stand-by mode to mute all mono channels while leaving the 2-track inputs active for background music playback while you're taking your break.
Feedback Channel Locating (FCL) System
FCL System indicator LEDs at the top of each channel light if the corresponding channel goes into feedback, so you won't have to fumble around searching for the channel that needs adjustment.
12 Inputs
Offers a total of 12 input channels - four for monaural microphone (incl. Phantom Power) or line input, plus four pairs that can function either as monaural microphone inputs or stereo line inputs - providing you with a versatile mix of input capabilities for a wide range of applications. If you need only microphone inputs you can use up to eight mic channels. Or if, for example, you want to play recorded background music during breaks (that's one stereo channel), and you have a keyboard player with a stereo-output keyboard (that's one more stereo channel), you still have six mic/line inputs. If you use all four stereo pairs to handle stereo line sources you have four channels available for mono mic or line input. This is a very versatile system that can adapt to your needs.
High Power For Main and Monitor Speakers
This powered mixer certainly don't skimp on power. Tthere's a power configuration to suit any application and venue. Also features a power mode switch that lets you use the two power channels as a stereo amplifier, or you can use one of the channels for the main speaker(s) and the other to drive monitors with a separate monitor mix set up via the channel MONITOR controls.
Yamaha Speaker Processing
Yamaha Club-series speakers are fine performers in their own right, but with Yamaha Speaker Processing you get extra-smooth highs and enhanced low-frequency output.
Durable, Lightweight Design
The EMX powered mixers offer the ideal combination of outstanding sound performance and easy handling. They're lightweight only 10 kilograms (22lbs.) and feature conveniently located handles for maximum carrying comfort. They're also built tough to withstand the rigors of use on the road.
