This rack setup is called a “slave” rack. Each of this “slave” racks, power two LA12 (LA12C)
and two LAS 218 speaker systems. In order to process the signal, a NEXT LMS 240i digital
processor is added to the first rack of the system, intitled the “master” rack, and then the
processed signal is passed from “slave” to “slave” by an LA Rack Systems Interconnection cable
(AM002).
2.2 NEXT LMS240I DIGITAL PROCESSOR
The LMS240i Digital loudspeaker management system is designed to optimize the
performance of a wide range of NEXT loudspeakers. It is a cost effective, single-rack space,
processor with fully controllable configuration and signal processing functions. The processor
is equipped with an LCD display and buttons via which it is possible to load set-ups from
memory and to modify some of the parameters of the current set-up. The LMS240i PC-
software allows the user to configure all parameters of the controller, storing them to the
processor by means of a simple USB computer connection. Superb audio quality and noise-
free operation is achieved by carefully optimized double precision signal processing coupled
with a 40-bit internal data path ensures a dynamic range in excess of 117dB. The high
sampling rate means minimal filtering providing exceptional sonic purity.
