LD SYSTEMS LECC DSP:
WHAT DOES LD SYSTEMS LECC DSP STAND FOR?
DSP is an acronym for Digital Signal Processing, and LECC stands for Limiter, EQ, Compressor and Crossover.
These functions are realised by a digital processor to attain perfect audio signal reproduction with maximum
definition and protect the system.
WHAT SPECIFICALLY DOES THE LECC DSP DO?
The Limiters protect the speakers and prevent distortion due to clipping. The bass, mid, and high frequency ran-
ges are each processed by a separate limiter that limits the signal if it exceeds a specific level that could have
negative consequences. Each limiter is optimized for its frequency band and seamless interaction with the other
ranges (multiband limiter). On the whole, this makes it possible to attain a higher sound level pressure, since
extreme signal peaks are limited automatically without having to reduce system volume.
The multiband EQ processes all frequency ranges. It is used for optimal tone control of the system.
The Compressor responds dynamically to provide a bass boost at low volumes for more punch. As volume
increases, the boost is reduced proportionally. The result is constantly controlled and perfectly adjusted bass
response.
The Crossovers control the separation of the frequency ranges to the individual speakers of the system, in other
words, the subwoofer and the mid-range speakers and tweeters of the coloumn. They are amplitude and low-
latency balanced to ensure that all frequencies are well-coordinated and reach listeners at the same time.
