2.2.2 DSP architecture

The proprietary algorithms allow optimum performance and protection of each individual transducer of the

L-ACOUSTICS

systems for an even more natural, transparent and realistic sound experience.

 The DSP engine is a 32-bit floating point DSP at 96 kHz sampling rate providing an enhanced dynamic range since

it does not generate calculation clips like a fixed point DSP.

 A dedicated engineering approach combining IIR and FIR filters generates perfectly linearized phase curves and

significantly improved impulse responses.

 The 4 x 4 matrix architecture offers flexibility for various system configurations.

 A delay of up to 1000 ms can be set for each output channel.

 The L-DRIVE transducer protection system offers advanced protection by simultaneously monitoring the excursion

and the temperature of the transducer.

 With a complete factory preset library and the possibility to create additional user presets, the flash memory

provides a quick access to all the usual L-ACOUSTICS

speaker system configurations (refer to the PRESET

GUIDE).
