DSP
Proprietary algorithms are processed in a 32-bit floating point DSP engine at a 96 kHz sampling rate. A dedicated engineering approach combining IIR and FIR filters allows generating perfectly linearized phase curves and significantly improved impulse responses for an even more natural, transparent, and realistic sound experience. Two cascaded 24-bit A/D converters at the front-end yield a ground-breaking encoding dynamic of 130 dB.
The L-DRIVE protection system carries out a dual analysis of signal level in real-time and RMS. Under extreme conditions when component membranes reach the over-excursion zone or if the coil ensemble temperature reaches a critical point, L-DRIVE acts as a power regulator. As a result the amount of power delivered at any channel is adjusted to the dynamic and thermal capacity of each individual transducer. This optimizes the power resources while preserving the highest dynamic range.
With a complete preset library and the possibility of creating additional user presets, the engineer is offered fingertip access to all the usual L-ACOUSTICS® loudspeaker system configurations.
AMPLIFICATION
The four amplifier channels driven by two inputs provide optimum system flexibility. The LA4 and LA8 offer two specific power ranges (4 x 1000 watts into 4 ohms, and 4 x 1800 watts into 4 or 2.7 ohms, respectively) yielding perfect power matching to each individual L-ACOUSTICS® loudspeaker system.
The built-in technologies allow control of the very wide dynamic range found in live audio productions while the high-efficiency components offer superior reliability, all from a sleek ergonomic package with exceptional weight/size ratio.
USER INTERFACE
The front panel user interface features extremely fast access to edit the 2 input and 4 output settings. The encoder wheel gives instant access to the user menus and the LCD screen offers real time visualization of the system parameters.
Command access includes mute, gain, preset selection, plus delay and polarity settings. Navigation through the menu pages is fast and intuitive. Beside the standard on-board preset library, the engineer can design and store his own settings (initialized from a standard preset template) in one of the 10 available user locations.
