Allen & Heath Zed-420 16 Mic/line 20 Input Mixer
MULTIPURPOSE MIXER WITH USB: FOR LIVE SOUND, RECORDING AND PRODUCTION
The ZED-420 has a fantastic pedigree which comes from nearly 40 years of making mixing desks for the professional sound community. The audio circuitry is based on years of continual development and refinement and the performance of all the elements within the mixer is has been perfected to ensure the very best sound quality possible.
This is a mixer for anyone, from entry-level to professionals, who appreciates fantastic sound, rugged build quality and imaginative feature sets. It’ll be equally happy running your gig on stage, recording live or mixing down in your studio at home.
We’ve teamed up with major software supplier, Cakewalk, to bundle its SONAR LE music creation and audio production software with ZED, giving you a fantastic, high spec digital audio workstation.
What’s great about the ZED-420?
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 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. The connectors are placed on the top surface for easy plugging & patching, and the 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 mixers.
The ZED 4-bus series is available with either 16 mono inputs plus 2 dual stereo channels (ZED-420), 24+2 (ZED-428) or 32+2 (ZED-436).
Also included with ZED 4-Bus is the excellent SONAR LE digital audio workstation software for Windows, with audio and MIDI multi-track recording and mixing capability, effects plug-ins and editing features, enabling the ZED 4-Bus mixer to become a live recording or home recording mixer.
Inputs
One of the great things about the ZED series is the number and variety of things you can plug in. In addition to the sixteen mono channels there are two dual stereo channels, each with a main stereo input on jack sockets and with additional inputs on phono sockets. the USB return can be selected to one of the additional inputs so that it feeds either the main LR bus or the stereo channel.
DuoPre
Based on the proven pre-amps from the hugely successful PA series, the ZED series has new DuoPre pre-amps, which use a two stage design, with carefully controlled amounts of gain in each stage. When amplifying the signal from the XLR input, the gain range is huge – 69dB of range to be exact – and is very evenly distributed around the gain control, meaning better control of signal level. Most of the gain comes from the first stage, so unwanted noise is kept to a minimum. Line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket, which has the great advantage of less noise when using the line input.
EQ Section
ZED-420 features a responsive 4-band EQ taken from the acclaimed GL2400 mixer. The design utilises MusiQ – optimised slope (or Q factor) for equalising individual instruments.
Auxiliary Sends
6 aux sends are provided, of which 1 & 2 are prefade for foldback monitoring, and 3 & 4 are switched pre or post-fade for effects sends and 5 & 6 are post-fade. Au
