Loudspeaker Management Systems
The concept of a Loudspeaker Management System is to provide all the processing
electronics you might need in one box. This typically includes crossover functions,
equalisation, limiters, delays and preset memories, that can store different set ups for
various applications. A loudspeaker management system offers better audio quality,
more precise control and loudspeaker protection because operating parameters can be
precisely matched to the individual loudspeaker components.
Digital processing enables steeper roll-offs through the crossover areas to be designed,
allowing more output from the speakers, as they are individually handling more
appropriate bandwidths. Also, the addition of delay to the LF signal to match the arrival
of the HF can help to make the image more intelligible. Therefore, it is much easier, and
more efficient, to manipulate audio digitally in low voltage electronics than in the passive
crossover networks found inside speakers.
The NuQ series has a choice of sub bass units (B15 or B18) that are designed to be used
actively with the NuQ-8, NuQ-10, NuQ-12 and NuQ-15 mid/top cabinets. The Turbosound
LMS-D24 and LMS-D26 loudspeaker management systems contain custom presets for all
the NuQ series models along with a world-class audio specification.
Turbosound LMS series loudspeaker management systems
The Turbosound LMS-D24 and LMS-D26 series are powerful DSP-based audio processing
units designed for use with Turbosound loudspeaker systems and associated bass
enclosures. The functions of multiple conventional products are combined in a compact
1U high 19” rack unit. They offer EQ, both for the room and the drivers, delay to align the
wave front, and limiters that can be set for each individual component to ensure against
damage and to protect the long term reliability of your speakers.
The LMS-D26 has two inputs and six outputs and the LMS-D24 has two inputs and four
outputs, all electronically balanced. The units are configured to provide specific
equalisation and crossover points aimed at optimizing the performance of these
Turbosound loudspeaker systems. In addition, limiters, delays, eq, gain, polarity, and
crossover filter controls are accessible to the user in order to match specific operation
environments. The LMS series crossovers are designed for quick setup and adjustment
via easy-to use front panel controls and, are ideally suited to both live sound and fixed
installation.
