ZED-420 is a 4-bus live sound mixer with 16 mic/line channels, 4 sub groups, 6 aux sends, USB stereo interface and Allen & Heath's 4-band MusiQ EQ — designed for bands and venues who need serious analogue mixing power.
USB Interface
Flexible Stereo Recording
ZED-420 features a 2 in / 2 out USB audio interface with flexible send options — Main Mix L+R pre or post-fader, Auxes 1–2 or Auxes 3–4. The USB return comes back in on a dedicated stereo channel for playback and monitoring.
MusiQ
Powerful EQ
Allen & Heath's analogue engineers designed the MusiQ EQ especially for ZED mixers. ZED-420 features a responsive 4-band EQ with sweepable high and low mid frequencies — more surgical control than the ZED Mid range, ideal for demanding live environments.
Audio Quality
Clean, Quiet, and Plenty of Gain.
The preamps on ZED-420 provide a huge 69dB of gain — enough for low output dynamic microphones and quiet acoustic sources — while keeping noise and distortion to a minimum.
Gain is evenly distributed throughout the control for precision at all levels, whether you're running a ribbon mic or a hot line signal.
