Allen & Heath ZED-420 Mixer

The Allen & Heath ZED-420 audio mixer with 16 mono inputs, plus 2 dual stereo channels, has a fantastic pedigree: nearly 40 years of making mixing desks for professional sound engineers. The ZED-420 mixer's audio circuitry is based on years of continual development and refinement. All the elements within the mixer have been perfected to insure the very best sound quality possible. The ZED series of 4-bus mixer's takes inspiration from other 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 ZED-14 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 the one employed in the successful GL series. The USB audio interface, with its uniquely flexible capability, allows different signals to be sent to USB, from L/R or from selected aux buses. The USB return signal can be routed straight to the L/R mix, or to a stereo channel. Connectors are on top for easy plugging and patching. Construction, with individual circuit boards firmly nutted to the top panel, is as rock solid as Allen & Heath's top-of-the-range ML Series audio mixers.
