MLA MINI    

USER GUIDE

CONFIGURATION OPTIONS

4 MLA Minis and one MSX can be rigged in four basic arrangements: two ground stacked, 
and two flown. The option chosen for any particular situation will be largely determined by the 
physical arrangements of the venue. Whichever arrangement is used, at least one factory preset 
is available for optimising the system’s performance in that configuration.

The rigging possibilities are illustrated below; see page 24 for full details of how to perform 
the actual physical rigging for each.
