Key Features
The Allen & Heath ML4000 is a large format VCA equipped dual function live sound console
providing many of the features of its larger brother the ML5000 . It can be quickly configured for
front-of-house (FOH) or stage monitor mixing. As one console suitable for both applications it is
equally well suited to installation, rental and touring. It offers an IO capability and feature set that
satisfies the latest trends in live sound engineering, in particular the growing number of inputs and
outputs for multi-speaker house and monitor systems, demands of stereo in-ear monitoring, 3
speaker LCR imaging, advanced grouping and automation. The design ensures on-the-road
durability, a clear layout for easy walk up and go operation, and no-compromise audio
performance.
