Yamaha has always strived to provide sound engineers with the purest possible signal instead of added processing or color to give it a 'signature' sound, and the MG Series is no exception. Embracing this philosophy of transparent sound, these mixing consoles deliver a level of sonic purity and sound quality that is unmatched in their class. This is where it all starts. Everything you do as a sound engineer is dependent on the quality of your preamps, which determines the direction your mix will take, and ultimately how good it is going to sound. MG Series mixing consoles feature Yamaha's studio-grade discrete class-A D-PRE preamps, which utilize an inverted Darlington circuit comprising two cascading transistors in a configuration that provides more power with lower impedance. Delivering fat, natural-sounding bass, and smooth, soaring highs, with very low distortion, D-PRE preamps possess an impressively wide frequency range that allows them to handle signals from any audio source without overly amplifying any specific elements of the sound. Having such a pure sonic platform to build on will ultimately save you time and effort by eliminating the need for excessive EQing or additional effects processing to 'fix' your mix.EQ and High-Pass FiltersThere'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. A high-pass filter allows you to eliminate unwanted low-frequency noise, for a smoother, cleaner mix.1-Knob CompressorsCompression 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.Built-in SPX Digital EffectsFor musical and non-musical applications, effects processing adds polish and professionalism to the mix. The MG X / XU models feature Yamaha's SPX digital multi-effect processor, offering a comprehensive suite of editable digital effects perfect for enhancing your mix, whether adding depth to a speaking engagement or breathing new color and atmosphere into a live performance.High-Quality Sound Op-AmpThe head amp determines sound quality, and op-amp integrated circuits are one of the most important parts of the head amp circuit. MG Series mixers feature new, high-quality, custom-made MG01 op-amps that we developed in cooperation with the semiconductor manufacturer. We worked directly with the semiconductor manufacturer to focus on sound quality first.D-PRE (Discrete Class-A Mic Preamps)This is where it all starts. Everything you do as a sound engineer is dependent on the quality of your preamps, which determines the direction your mix will take, and ultimately how good it is going to sound. MG Series mixing consoles feature Yamaha's studio-grade discrete class-A D-PRE preamps, which utilize an inverted Darlington circuit comprising two cascading transistors in a configuration that provides more power with lower impedance.
