MLA MINI    

ADVANCED USER GUIDE

SYSTEM CONFIGURATION USING ON-BOARD PRESETS

An MLA Mini system can be rigged in a wide variety of ways, in both ground-stacked and flown 
configurations. The system size and rigging option to be used will generally be dictated by the 
venue’s size and physical restrictions.

To achieve the best performance from the system it should be optimised both physically and 
electronically. This optimisation can be achieved in two ways – by using internal factory Presets, 
or through the use of two software applications: 

Display 2.2

 and 

Vu-Net

.

The use of Presets greatly simplifies the system optimisation procedure, but note that the six 
Presets pre-loaded into the MSX sub are only applicable to the minimum MLA Mini configurations 
consisting of one MSX sub plus four MLA Mini cabinets (per side). For all larger configurations, 
the two software applications must be used.

The configuration options using Presets are discussed below. Configuring systems using Display 
2.2 follows at page 30.

Using Presets

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. In the manual section 
on Rigging, the Preset appropriate to each rigging configuration is indicated by an icon thus:

The rigging possibilities are illustrated below; see page 54 for full details of how to perform 
the actual physical rigging for each.
