DSM-480LAN and DSM-240 are professional digital speaker management systems of high power capability with state-of-the-art DSP processors and digital converters.These systems combine active crossover network, parametric equalizer, delay, RMS compressor and peak limiter in one unit. Thus, they are powerful tools in order to control every important feature necessary for a perfect speaker management in PA applications or for developing active speaker systems. Every feature and adjustment can be edited directly at the unit or via the USB interface, RS-485 interface or LAN TCP/IP interface (DSM-480LAN only) on the PC by means of an intuitively operated graphical user interface and then be stored in individual presets.Digital speaker management system4 inputs and 8 outputs (XLR, balanced)2 x S/PDIF digital input, stereoDSP: 2 x DREAM SAM3716, 24 bits (data) x 96 bits (coeff.)Dynamic range: > 110 dBRouting matrix for routing the inputs to the outputs as desiredGraphical user interface, PC editing software (up to 32 x DSM-480LAN can be administered)24 user presets can be storedFlash card for reading and storing presetsIntegrated tone generator for pink noise and white noiseRemote control via USB, RS-485 or TCP/IP LAN.

A level limitation and smooth compression in each frequency range as well as fine adjustments of equalizers, special filters and the high-precision delay allow for a high-level tuning." Xound 01/2013"I must confess, it is quite tempting when you have the choice of so many high-performance tools. However, you should concentrate on the essential requirements. During practical applications, we used the high-pass filters and low-pass filters as an active crossover network in order to separate the top parts from the subwoofer. We adjusted the frequencies of each speaker component and set the compressor functions to allow for the speakers to provide a pleasant reproduction, even after turning up the volume. The limiter was used as a kind of emergency break, before the limiters of the power amplifiers became active. The complete performance was considerably enhanced and provided a far more transparent overall sound ... The result was amazing. Our test showed that the smart DSM-480LAN features enormous processing reserves which could be used for very flexible applications due to the open design with four inputs and eight outputs. In case you require more channels when using larger PA systems, further units can be cascaded. The investment is clearly worth it." tools4music 01/2013"This unit provides everything required from a professional controller, perfectly suitable for the ambitioned sound engineer.
