Recognizing that the working musician often works without a sound crew, Mackie's intuitive DFX series mixers provide all one needs for smaller live sound applications. The Mackie DFX-12 features 12 balanced 1/4" TRS line inputs. Channels 1-4 are mono inputs while 5 through 12 are stereo paired. Inserts on channels 1 through 4 are also provided. 6 Ultra Low Noise mic preamps provide a low noise floor and high dynamic range on input. The DFX-12 features an internal 32-bit EMAC effects processor complete with reverb, chorus, flanger, delay effects and more. A 5 band graphic EQ is featured on the main stereo bus.
