1. Introduction
The digital signal controller LMS244 is a modern loudspeaker system controller designed for a
maximum of operational safety. 2 Inputs and 4 Outputs enable its use in 2-way stereo operation or for
the driving of 3 to 4-way combinations in mono operation.
Furthermore, the LMS244 offers totally unrestricted system configuration possibilities by means of the
Microsoft-Windows software supplied with the device.
Functions and characteristics of the LMS244:
• High-resolution 24-bit converters with 96Hz sampling frequency.
• Digital Input with sample rate converter.
• Mathematical standard filters with up to 48dB/octave, or in custom-mode, free filter parameter
definition up to 8th order.
• Internal summing of inputs A & B forming a third input signal.
• Input delay stage with six parametric EQ’s for individual tonal definition.
• Precise limiter function, with gain and noise gate features for each output.
• Each output combined with six, system correctional parametric EQ’s and a delay stage for run-time
adjustments of each loudspeaker.
• Import of measurement-data (ASCII) for complex equalization of the connected loudspeaker
systems.
The following are just some of the operations possible with the LMS244:
• 3- or 4-way PA mono processor
• 3-way PA mono processor with sub-bass output through Aux. send.
• 2-way stereo processor.
• 2-way stereo processor with mono sub-bass + Aux.
• 4-output distribution system.
• Stereo parametric equalizer.
• Stereo delay line with EQ.
• Stereo compressor/limiter.
The editing software (for Windows® 95/98/NT/2000/Me/XP) supplied with the unit is specifically
designed for the modification of all parameters of the controller. Please study this software instruction
manual carefully before attempting to alter or build set-up configurations.
Optimal configurations of some of Space Equipment´s loudspeaker systems, as well as free memory
space for user-configurations, have been loaded into the LMS244 prior to shipping. Using the LMS244
software, the user is able to modify or configure ALL parameters of the LMS244.
Subsequently, it is only possible to change the configuration and the parameters needed for the tuning
of a system to an installation situation from the device itself (delays, gains and polarities) whereas the
parameters that characterise the equipment (EQ, crossover and limiter) remain hidden from all but the
system engineer. This ensures that no unauthorised personnel can change important system settings,
greatly increasing equipment security. For more information about front panel adjustments please read
the instruction manual for the unit.
