Multipurpose USB mixer for live sound, recording, and production.

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 DuoPreTM 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 that employed in the successful GL series.

The USB audio interface, with its uniquely flexible capability, allows different signals to be sent to USB, from LR or from selected aux buses. The USB return signal can be routed straight to the LR 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.

Allen & Heath includes the excellent SONAR LE digital audio workstation software for Windows with The ZED-420 mixer. With audio and MIDI multi-track recording and mixing capability, effects plug-ins and editing features, SONAR LE enabes the ZED-420 4-Bus mixer to become a live recording or home recording mixer.

A great general-purpose live mixer

Comments about Allen & Heath ZED-420 Mixer:

If you've worked on an A&H GL2400 series board, the ZED-4 series will feel right at home. Same great build quality in a mixer dedicated to the live mixing role. All the features you'd expect of an Allen & Heath board: per-channel phantom power, per-channel pre/post switching of auxes 3 and 4 (so they can be used as monitor or recording mixes), L/R/M masters (the M is independently assignable by channel, making subwoofer or center feeds easy), PFL/AFL with an easy-to-read layout, and a host of other GL-inspired features.Two features I really like are the two-channel matrix and the USB output. If you need a feed from your live board to record to a laptop computer, this is your mixer. First of all, the matrix is a mini-mixer; you can mix any combination of the post-fade signals from L/R, M and each of the four groups. This allows you to boost those backline sources with heavy stage presence, such as drums, without making the live mix too heavy. Then, the USB port allows you to plug virtually any laptop directly into the board (no adapters needed) and record in crisp digital format from either the LR feeds, auxes or matrix.For the more advanced signal tweakers, inserts are available on each channel, aux and main feed to add compression, gating, EQ, and effects as necesary. Direct outs on all 16 mono channels also allow for interfacing with a multitrack recorder or recording mixer.While flexible, the mixer also requires some attention; this isn't your kiddie "set and forget" garage band board. A truly beautiful mix is possible if you know what you're doing, but the inverse is also true.

Comments about Allen & Heath ZED-420 Mixer:

I have used this at my church, its a great mixer but... I like to do computer recording and when I heard they had a new mixer I came into try it out. The only downside other than the price is that you can only get a left and right mixer out. I would have like to have the 4 aux's coming out but thats not going to happen....
