These systems combine the components active crossover, parametric equalizer, delay, RMS compressor and peak limiter in one device. This makes them powerful tools for controlling all of the important functions that are necessary for optimal loudspeaker management in sound reinforcement technology or the development of active loudspeaker systems. All functions and settings can be edited directly on the device or using the intuitive graphical user interface on the PC via the USB, RS-485 or LAN-TCP/IP ( DSM-480LAN only) interface and saved in individual presets. Digital speaker management system 4 inputs and 8 outputs (XLR, balanced) 2 x S/PDIF digital input, stereo DSP: 2 x DREAM SAM3716, 24 bit (data) x 96 bit (coeff.) dynamic range > 110 dB routing matrix for arbitrary routing of the inputs to the outputs Graphical user interface, PC editor software (up to 32 DSM-480LAN manageable) 24 user presets can be saved Flash card for reading and saving presets Integrated tone generator for pink noise and white White Noise Remote control via USB, RS-485 or TCP/IP-LAN. With the optionally available USB/RS-485 converter DA-70157, a PC or notebook with a USB interface can be connected to the serial RS-485 interface and several interconnected devices can be addressed and configured. Dot matrix display with 2 x 24 characters VU meter with 7 LEDs per channel, optionally for level display or limiter 482 mm rack installation (19"), 1 U input (data per channel) gain Noise Gate 5 parametric equalizers with 17 Filter types (see graphic) delay switchable between time (ms) and distance (m): maximum 849 ms in steps of 22 µsec or maximum 288 m in 6.8 mm steps Output (data per channel) Crossover with Butterworth, Linkwitz -Riley and Bessel filters as well as individually adjustable filter types from 6-48 dB/oct 7 parametric equalizers 17 filter types per equalizer to choose from (see graphic) Routing matrix with routing mix for level adjustment Peak limiter and RMS compressor with ratio up to 32: 1 and adjustable soft/hard knee, threshold from 20 dBu to -10 dBu, release time from 0.1-3 s, attack time 5-200 ms peak limiter and RMS compressor with bypass function delay switchable between Time (ms) and distance (m): maximum 849 ms in steps of 22 µsec or maximum 288 m in 6.8 mm steps Phase switchable (180°) gain Tools4music 01/2013 "The ambitious sound engineer will find everything here one would expect from a professional controller. Distortion, noise, maximum input levels - the DSM-480LAN meets professional measurement requirements."
