Then you can use the 100Hz low cut control to keep your sound clean. Next, you can dial up to 60dB of gain before sending it through onboard compression and 3-band EQ. Every channel is equipped with FX level controls and a mute button. What's more, every mic input is equipped with 48V phantom power. Improved digital effects To make sure that you sound perfect, the Mackie ProFX22v3 has an onboard effects processor. The effects processor has a blend function, FX level control, and a quick mute switch. The GigFX effects engine offers up 24 different effects ranging from delays, reverbs, choruses, distortion, and even an auto-wah feature. All of these effects are accessed by a simple twist of the Presets knob. Exceptional build quality Mackie mixers have been a mainstay for studio and live sound for many reasons.
