Allen and Heath ZED420 20-Channel Mixer with USB Interface

The ZED 4-Bus series takes inspiration from different product lines within the A&H range, combining them with fresh new ideas to give stunning results in a neat and easy to use package.

The padless DuoPre mic/line pre-amplifier is the new design first implemented on the ZED14 and delivers a high-headroom, low-noise signal.

The 4 band, 2 sweep EQ, along with the low noise summing amps, is borrowed from the acclaimed GL2400, while the bus architecture is a simplified, but equally comprehensive, version of that employed in the successful GL series.
