One of this mixer's innovations is Automix™ technology, an automatic mixing function provided on the first four channels. Once engaged, Automix monitors the levels on these channels and automatically turns down unused or low priority inputs to give dominance to the main microphone, minimizing ambient noise and feedback. The S-14 also includes a built-in Feedback Ferret® automatic digital feedback elimination system on the Main and Monitor 1 outputs. The Feedback Ferret applies a narrow notch filter on specific problem frequencies to eliminate feedback without sacrificing tonal quality. The device continuously checks and rechecks the designated problem frequencies and then releases the filter(s) when it no longer detects feedback.

Another feature unique to the S-14 is Mid-Morph equalization, which is actually two EQ controls in one. When the knob is cut, it pulls out low-mid frequencies that muddy the sound; when boosted, it shifts to an upper-mid frequency that brightens the vocal range. Every channel includes Mid-Morph EQ as well as normal low and high EQ.

The stereo line channels also accommodate split-accompaniment audio tracks. The accompaniment can be played to the main system in stereo or from the left or right inputs, while the Monitor Blend control allows any mix of vocals and accompaniment to be sent to the monitors.

In addition, the S-14 features digital reverb with four presets and a mute; vocal enhancer; compression; phantom power and much more.

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 EMX512SC 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!

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

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.

Durable, lightweight design
At only 22 pounds and equipped with conveniently located handles, the EMX512S is easy to transport. It's built to withstand the rigors of the road and deliver reliable performance, night after night.
