If more than three additional acoustic enclosures per channel are required for a given application, 

it is sufficient to add a second 

flight case

, and so on successively until the required final number of 

acoustic enclosures has been obtained. In any case, 20 acoustic enclosures per flying column should 
not be exceeded, given the load capacity of the system. 

 

Please refer to section 5 for further information regarding BET ACOUSTICS MASS1015 line 

array configurations. 
 
 
4. ASSEMBLY AND CONNECTIONS 
 
 

The acoustic enclosures of the MASS1015 system have been carefully studied and designed for 

rapid, efficient and secure assembly, disassembly and storage of a line array: 
 



Handling and operation of the BET ACOUSTICS MASS1015 system is simple owing to the 4 
transport handles. 



All of the units can be stacked together, forming easily handled, stored and transported clusters. 



The reduced weight and compact size of each unit facilitates their handling. 



The configurations can be kept assembled after events, both for transport as well as storage. 



The flying system between enclosures contains only one type of connecting rod for easy 
disassembly of units. 



All fastenings are made with pins with magnetic heads for rapid handling. 



The elevation mechanism is easily disassembled. 



One single pin is used for all necessary functions as regards interconnection of units. 



The STACK OUT output of each enclosure allows parallel connection of up to four acoustic 
enclosures. 

 
TRANSPORT, STORAGE 
 

The most practical and usual way of transporting the BET ACOUSTICS MASS1015 system is in 

configured clusters of 3 or 2x3 units. In this way the configuration of the vertical coverage of the system 
can be maintained in addition to enabling transport of the iron elevation fittings installed in the same 
cluster. 
 
CALIBRATION OF VERTICAL COVERAGE 
 

The calibration of vertical coverage of the system is easily carried out prior to being flown. The 

positions of the pins are altered as indicated on the silk-screen print on the lateral, frontal iron fitting, the 
intervals of the positions being 1º. 
 

The positions of the pins of the rear laterals are not changed as the rear mechanism is only 

intended to serve as a hinge.
