LINUS14D
The controller output stage should deliver an output power of 4 x 3,500 watts RMS at 4 ohms. It should be optimally adapted to connected full-range loudspeaker systems, bass expansions and low bass expansions 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, eight digital AES/EBU and 4 digital DANTETM inputs, as well as four outputs. The balanced analog inputs should have an input impedance of 12 kOhm. The four outputs should have a signal-to-noise ratio of <111 dB (A-weighted) when using the analog inputs, and <119 dB (A-weighted) when using the digital inputs. The attenuation factor should be >10,000 (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. For each channel of the power electronics, an integrated capacitor for the use of sensor-controlled bass and deep bass expansions should be available. The special sensor subwoofers should be connected via two 5-pin XLR connection fields located on the rear panel. 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 two RJ-45 inputs and outputs on the rear 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 user specific filter parameters. It should also be possible to display input and output levels and states, component loads, and network characteristics and noise. An integrated XLR connector panel with all balanced analog signal inputs, all digital AES/EBU inputs (via RJ45 connectors), and a DANTETM input should be located on the rear panel. Two NL4 outputs and one NL8 output should be available for the speaker outputs. For the power supply, a 32A PowerCon should be located on the rear side. Its physical dimensions should be 483 mm in width, 88.9 mm in height and 453 mm in depth. It is to be able to be mounted in 19" racks with rack tubes provided for this purpose and use 2 height units. The weight of the controller output stage should be 14.75 kg. The manufacturer's warranty should be 5 years.
