LINUS-10C

The controller output stage should deliver an output power of 4 x 2,200 watts RMS at 4 ohms. It should be optimally adapted to connected full-range loudspeaker systems, bass extensions and low bass extensions by providing loudspeaker presets. The DSP processing in the loudspeaker presets will take place in IIR and FIR filter technologies. Pre-calibrated contour filters, as well as real-time protection functions against thermal overload and excessive membrane deflection of the loudspeaker, as well as runtime and phase corrections. The DSP architecture will include four analog, four digital AES/EBU inputs and four outputs. The balanced ana- log inputs should have an input impedance of 16 kOhm. The four outputs should have a signal-to-noise ratio of <115 dB (A-weighted) when using the analog inputs, and <117 dB (A-weighted) when using the digital inputs. The attenuation factor should be >600 (at 1 kHz and 8 Ohm). The DSP with 32-bit floating point processing should operate at 96 kHz sampling rate and use cascaded A/D converters. The latency of the system should not exceed 0.6 ms with minimum processing. The TCP/IP network protocol for remote control of the controller output stage should operate at a speed of 100 Mbit/s and enable remote monitoring of up to 100 devices in a star-shaped, concatenated or hybrid arrangement. The electrical connection of the network is to be made via a rear RJ-45 input via CAT5e U/FTP (or higher) cable. Free remote control and monitoring software for Mac and PC will provide access to signal routing, polarity, muting and gain parameters, delay time and para meters of user specific filters. In addition, input and output levels and states, component loads, and network characteristics and noise should be displayed. An integrated XLR connector panel with all balanced analog signal inputs and all digital AES/EBU inputs (via RJ45 connectors) should be located on the rear panel. Two NL4 outputs and one NL8 output should be available for the loudspeaker outputs. For the power supply, a 32A PowerCon should be located on the rear panel. Its physical dimensions should be 483 mm in width, 88.9 mm in height and 453 mm in depth. It should be able to be mounted in 19" racks with the rack tubes provided for this purpose and use 2 height units. The weight of the controller output stage should be 14.3 kg. The manufacturer's warranty should be 5 years.
