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.
