Allen & Heath ZED-428 Live Audio Mixer


Allen & Heath ZED-4 series mixer has been carefully and lovingly designed in the beautiful county of Cornwall in the UK and is manufactured alongside a wide range of professional audio mixing consoles. Many of the components used in ZED are exactly the same as in the larger Allen & Heath products and the construction methods are also very similar ‚utilizing individual vertically mounted channel circuit boards with each rotary control fixed with a metal nut to the front panel. This provides a very robust product that will resist damage and give years of reliable use. It also makes servicing much easier should it be required, with the ability to remove one particular channel from the mixer at a time, or easily change a fader. The audio circuitry is based on years of continual development and refinement, the performance of all the elements within the
mixer scrutinized and perfected to ensure the very best sound quality possible.
Mic/Line Pre-amps:
Based on the pre-amps from the PA series, the ZED series pre-amps 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
irst stage, so unwanted noise is kept to a minimum. There is no “pad” switch, or pad circuit — line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket. This has the great advantage of lower noise when using the line input.
