Whether you need excellent sound for a live concert, house of worship, theater, sound reinforcement, or other AV application, the versatile ZED-428 24-Channel Mixer from Allen & Heath gives you the professionalism and quality you crave from both your live and recorded audio. Delivering the tools you need to take your audio project to the next level, this mixer boasts 4-band EQ, DuoPre amps, as well as 24 mic or line inputs plus 2 dual stereo inputs, 4 sub-groups, 6 auxiliary sends, and a 7×2 matrix.

Built into the ZED-428 is a responsive 4-band, swept mid-frequency EQ design at uses MusiQ. Its optimized slope (Q factor) allows you to precision-equalize individual instruments in your band.

The ZED-428 includes DuoPre pre-amplifiers that use a 2-stage design and carefully controlled gain in each stage. These preamps boast a gain range of 69dB and reliably-even gain control when amplifying a signal from the mixer’s XLR input. Most of the gain comes from the first stage, which keeps unwanted noise to a minimum. Plug line level signals into the preamp’s second stage using the line input jack socket, which results in less noise when using line input or when matching a higher input impedance.

The ZED-428 comes with configurable USB audio inputs and outputs. No need to install external soundcards—just plug in a USB lead and select USB routing on the mixer to get started right away at your recording. This feature gives you CD-quality audio to and from your Mac or PC, while switches and connections via the mixer’s jack socket terminals offer a variety of send/return options. Rounding out the ZED-428’s connectivity options are 2 stereo inputs for MP3/CD players or keyboards, as well as professional XLR stereo outputs and a versatile monitoring section that lets you plug in headphones and/or speakers.
