ML4000 23 buss live sound VCA console 40 Mono and 2 Stereo

ML4000 sits squarely in the centre of the ML series, providing an ideal solution for those customers who need similar functionality to the ML5000 but who can't justify the size or expense.

The console boasts advanced VCA capability and our innovative LCRplus panning system. We even found a way to provide a similar level of show automation capability to ML5000, thanks to our archiver / snapshot PC software
