L-Acoustics LA7.16i

System amplifier (class D) for installations, with an output power of 16 x 1300 at 8 ohms, A/D converter, and integrated DSP processor. Flexible 16 x 16 routing and summation matrix with 16 inputs and 16 outputs. Power supply via SMPS (Switched Mode Power Supply) with power factor correction (PFC) and 24V DC backup supply input. Advanced DSP algorithms optimize real-time performance from available SMPS and amplifier resources. Heat dissipation by DSP-controlled fans. Analog audio input and digital (AES/EBU) audio input with active links. Phoenix terminals for input, output, and GPIO connections. Ethernet connections to pass Milan-AVB audio and for remote control and monitoring. The DSPs process IIR and linear phase 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 manufacturers' 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. Integration into higher-level media control systems is possible by means of software modules.
