 ML4000 - Call for pricing - 23 Bus Live Sound VCA Console
Downloads
ML4000 sits squarely in the center 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 the innovative LCRplus panning system. Allen & Heath even found a way to provide a similar level of show automation capability to ML5000, thanks to their archiver/snapshot PC software.
The ML4000 is the ideal all-purpose solution for install, PA hire and touring applications, handling both front-of-house and stage monitor mixing with ease. With the intuitive layout, and the traditional British EQ and high-definition preamp, getting the right sound couldn’t be easier.
NEW: There is now a ‘B’ Option available with first 4 mono channels to the right of the master section replaced with 4 stereo channels.
