Premium A&H Sound Plus Easy USB!

Allen & Heath's ZED-420 sports all the essentials you need for flexible live mixing: 16 channels with smooth, long-throw faders, 4-band EQ with swept mids, six aux sends, and four sub groups. You also get a direct out on every channel and master level controls on all outs. It's an incredible amount of flexibility, at a awesome value, but Allen & Heath added another dimension of functionality to the ZED-420: USB connectivity! Now you can get clean, clear audio straight into and out of your computer with the ZED-420.

Allen & Heath ZED-420 at a Glance:

• Legacy
  
• Best of previous designs
  
• USB

Legacy
The ZED-420 has a fantastic pedigree which comes from nearly 40 years of making mixing desks for the pro sound community. The audio circuitry is based on years of continual development and refinement and the performance of all the elements within the mixer has been perfected to ensure the totally best sound quality possible.

Best of previous designs
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 really simple 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, plus the low noise summing amps, is borrowed from the renowned GL2400, while the bus architecture is a simplified, but equally comprehensive, version of that used in the successful GL series.

USB
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 simple 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. Allen & Heath 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.
