Tailored mixes
The Mackie HM-400 offers four independent input channels and a total of 12 headphone outputs, making it the perfect addition for any professional musician or recording engineer wishing to expand their current set-up.
Whether you're on stage or in the studio, solid headphone mixes are a necessity for inspiring musicians to achieve powerful performances. The flexibility and versatility of the Mackie HM-400 ensure that the performer has total control over their sound. Users will be able to apply an extremely musical two-band EQ to their headphone mix, giving them the ability to cut or boost bass and treble frequencies to taste.
Each channel can be set to one of two modes: stereo or two-channel. The stereo setting ensures that the width and depth of the mix are maintained across all headphones, whilst the two-channel option sums the signal to dual mono, allowing you to check phase coherency and ensuring consistent sound across all headphone types.
