LA4 ( R2 ) L-ACOUSTICS AMPLIFIER AND PROCESSOR

LA4 - Amplified controller

The LA4 amplified controller belongs to the generation of high-end integrated controllers totally dedicated to controlling L-ACOUSTICS ® speaker systems. The LA4 combines in a 2U format the resources of a 2 x 4 DSP driving four amplification channels delivering up to 10 00 watts each, a complete factory preset library, an intuitive user interface, two Ethernet connection ports for driving network, a connection panel for audio inputs and speaker outputs, and a slot for an optional AES / EBU input card.

Complete steering system

• Factory presets for passive and active modes

• Flexible matrixing between the two inputs and the four amplified outputs

32-bit floating point DSP, 96 kHz sampling

• Cascaded 24-bit A / D converters, 130 dB dynamic range

• Combined IIR / FIR algorithms

• Adjustable entry and exit times

• Section dedicated to the equalization of systems, controllable from the LA NET WORK MANAGER software

• Real-time excursion and temperature control using the L-DRIVE process

• Fixed latency = 3.9 ms (or 3.4 ms with optional AES / EBU card)

4-channel amplification
