L-Acoustics LA2Xi

System amplifier (class D) for installations, with an output power of 4 x 360 W RMS at 8 ohms, A/D converter and integrated DSP processor. Flexible 4 x 4 matrix with 4 inputs and 4 outputs. Outputs can be bridged in pairs with an output power of 2 x 1260 W at 8 ohms. All four output channels can be bridged into one high power output channel of 2550 W. Power supply via SMPS (Switched Mode Power Supply) with power factor correction (PFC). Phoenix terminals for input and output connections. Heat dissipation by temperature-controlled fans. Ethernet connections to pass AVB audio and for remote control and monitoring. Analog audio inputs and digital (AES/EBU) audio inputs with active links. The DSPs process IIR and FIR filters, enable real-time adjustments, contour filters and filters to compensate for air absorption. Protection against thermal overload and over-excursion. Built-in library with factory presets for all manufacturer's loudspeakers and 10 user memories.

Ethernet based control network with up to 1 Gbit/s. Support of digital audio signal transmission via the Milan AVB protocol with seamless redundancy. "Automatic fallback" options are also possible. Design of control networks with up to 253 controller power amplifiers in star, daisy chain or hybrid arrangement. The controller power amplifiers and computers in the network are connected via CAT5e U/FTP or higher, with standard RJ45 connectors. The network management software can be run on both Windows and Mac OS X and is designed to include component load, signal levels, limiter activity, overload, and fault messages. It is also used to manage presets, as well as to adjust input gain, mute, delay correction and filtering. Possible integration into higher-level media control systems by means of software modules.
