Audio professionals looking for a high-quality mixer with premium effects will be impressed with the Yamaha MG12X, a compact mixer capable of twelve simultaneous inputs that is ideal for performances, recordings lectures and more. The mixer features four mono mic/line combo input channels, two stereo line input channels that can also be used as mono mic or line inputs (XLR and stereo 1/4" inputs), and two stereo line inputs with 1/4" and RCA jacks.

Channels 1-8 are each equipped with D-Pre mic preamps, 3-band EQ, pan control and a high pass filter. The D-Pre mic preamps feature an inverted Darlington circuit and switchable 48V phantom power for use with dynamic and condenser microphones. Channels 1-4 each feature 26 dB attenuation switches for use with loud sound sources such as guitar amplifiers and drums. The MG12X mixer has XLR and TRS stereo outs for connecting to your PA system or monitor speakers. It also has a 1/4" headphone output with level control for personal monitoring, as well as additional TRS 1/4" stereo monitor outs for sending to powered speakers, amplifiers or devices such as digital recorders.

Each of the MG12X's channels feature a dedicated FX-bus-send level and there are 24 effect presets to choose from. The overall level of the FX bus is controlled by the dedicated FX-return level control. Providing reverbs, delays, phaser, flanger, chorus, tremolo, auto-wah, distortion, and more, these effects can be used to help vocals and instruments sit better in your mix.

Compression plays an essential role in just about any recording or sound reinforcement environment by altering the level of dynamics of an audio signal when you need livelier guitars, punchier bass lines, a tighter snare, or a cleaner vocal sound. However, it can take countless hours to master the complexities of even the most basic outboard compression units and use them effectively. Originally a Yamaha innovation, 1-knob compressors are now an industry standard that gives you instant access to optimized compression settings via a single rotary control.

There's nothing more useful than reliable equalization when you need nuanced management of your tone. The MG Series benefits from Yamaha's unparalleled experience in designing pro audio gear, featuring 3-band equalizers on all mono channels for precise control of your sound. High-pass filters allow you to eliminate unwanted low-frequency noise, for a smoother, cleaner mix.

MG Series mixers feature up to aux sends for expanding your sound reinforcement or recording setup, allowing you to incorporate additional effects, output to external recording devices, or feed to a monitoring system. Master send controls are also provided.

For musical and nonmusical applications alike, effect processing adds polish and professionalism to the mix. The MG12X features Yamaha's acclaimed SPX digital multi-effect processor, offering a comprehensive suite of 24 editable digital effects, perfect for enhancing your mix, whether adding depth to a speaking engagement or breathing new color and atmosphere into a live band performance. In particular, the high-quality reverb and delay expand the spatial quality of the sound with remarkable realism and naturalness. You can even connect an optional FC5 footswitch for effect on/off control.
