The Yamaha EMX312SC is a sturdy lightweight mixer with dual 300-Watt amps, 16 Yamaha SPX effects, built-in graphic EQs, one-knob compression on the mono input channels, and mucho 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.

The EMX312SC 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. 16 built-in Yamaha SPX effects let you add reverb, echo, chorus, flanging, phasing and even distortion to your mix and 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. The EMX312SC also includes one-knob compression on the mono input channels. The FCL Feedback Channel Locating system is an LED at the top of each channel that lights if the corresponding channel goes into feedback, allowing you to reduce the gain on the offending input channel.
