Allen & Heath ZED-18 Compact 18-Channel Analog Mixer with USB Connection


The Allen & Heath ZED-18 is a compact 18-channel analog mixer offering versatile I/O and a user-friendly workflow for use in home and project studio recording, houses of worship, and live sound reinforcement. The 10 mono channels feature Neutrik XLR mic and 1/4″ line inputs, DuoPre preamps with phantom power and bountiful gain, 1/4″ insert points, and 3-band EQ, while the four stereo channels have 1/4″ inputs and 2-band EQ. All channels are equipped with long-throw 100mm faders, solo and mute buttons, and independent aux send knobs.

The four aux sends are ideal for routing to floor monitors and outboard time-based effects. A USB 1.1 port delivers 2-channel send and return capabilities via a Mac or Windows computer. There are stereo and mono main outputs in addition to alt and headphone outputs, and dual 12-segment LED meters that clearly indicate your master output level. Patch additional stereo sources into the RCA stereo return and 2-track inputs, then route them to the stereo bus, or mix them into the stereo channels. The stereo RCA output is handy for recording your mix to an external device such as a cassette deck or computer soundcard.

10 Mono Inputs

There are 10 mono input channels with Neutrik connectors—XLR for balanced mic signals, and 1/4″ for balanced/unbalanced line-level sources

Four Stereo Inputs

The four stereo input channels feature 1/4″ connectors to accommodate stereo devices such as keyboards, synth modules, and external effects processors

Flexible EQ Section

All mono channels feature 3-band EQ with sweepable midrange, while the stereo channels offer 2-band EQ


Inserts on all mono channels and the stereo output provide easy integration of analog outboard gear such as hardware compressors and equalizers

Independent Aux Sends

Four mono aux sends with independent level controls allow versatile signal routing to floor monitors and external effects processors

USB Connection

A USB 1.1 port allows direct connection to Mac and Windows computers for stereo audio I/O

Flexible Outputs

The ZED-18 offers balanced XLR stereo main outputs, a 1/4″ mono main output, 1/4″ and 3.5mm stereo headphone outputs, and a source-selectable stereo alt output
