AH-ZED428

The Allen & Heath ZED-428 is a professional 4-bus analog live sound mixer with 24 mic/line channels and a built-in 2-channel USB stereo interface — ideal for live venues, houses of worship, and installed AV environments that demand professional-grade audio with multi-channel flexibility.

From The Manufacturer

The ZED Max range features Allen & Heath's largest analogue live sound mixers, designed for bands and venues who need up to 36 input channels plus 4 groups and stereo recording. All ZED Max models feature a 2-channel USB interface with flexible send options including Main Mix L+R pre or post-fader, Auxes 1-2, or Auxes 3-4. The USB return comes back in on a stereo channel for playback and monitoring. The MusiQ EQ was designed by Allen & Heath's analogue engineers specifically for ZED mixers, carefully optimising curves and target frequencies for musical response that works equally well on stage or in the studio. ZED Max preamps deliver 69dB of gain — enough for low-output dynamic microphones and quiet acoustic sources — while keeping noise and distortion to a minimum.
