Allen & Heath ZED-420 16-Channel Analog USB Mixer

This member from Allen & Heath's ZED 4 BUS roster is the ZED-420, ideal for bands, houses of worship, theatres or AV applications and other live sound and recording uses. The ZED-420 is graced with a truly professional feature set, which will fit any sound reinforcement application and professional PA hire stock. ZED-420 has Configurable USB audio in/out makes it easy to capture stereo recordings, 16 mic or line inputs plus 2 dual stereo inputs, 4-band EQ with MusiQ, 4 sub-groups, 6 auxiliary sends and a 7×2 matrix.

The USB audio flexibility means no clumsy efforts with soundcard inputs, only to find that the levels are all wrong and noisy. Just plug in a USB lead to your ZED, select the USB routing on the mixer and the device on your computer and that’s it! CD quality audio to and from your PC or Mac. The ZED-420 has a tuned 4-band EQ taken from the acclaimed A&H GL2200 mixer, utilizing MusiQ – with optimised slope (or Q factor) for equalising individual instruments.

And based on the proven pre-amps from the hugely successful PA series, ZED-420 has 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.
